1. FY09 GOES-R3 Project Proposal Title Page • Title: Nearcasts - Filling the gap between Observations and NWP using Dynamic Projections of GOES Moisture Products • Project Type: GOES Utilization Proposal – Application of GOES-R ABI • Status: Ongoing – Preparing for NWS Field evaluation • Duration: Reporting on 1st year of 3 year proposals • Leads: • Ralph Petersen (CIMSS), Bob Aune (NESDIS) • Other Participants: • NWS forecast offices, NWS Regional SSDs, NCEP AWC • Nearcasts – • Increasing the use of GOES data • -Filling the 4-5 hr information gap • between • Extrapolation based Nowcasts • (using primarily Radar Data) • and • NWP based Forecasts Filling the Gap 0-1 hr 6 hrs and beyond
2. Project Summary – Fundamentally unchanged from 2007 Review • The overall goal of this project is to provide forecasters with new tools to help identify areas where convection is and is not likely 3-6 hours in advance of storm development using moisture and temperature products from future GOES satellites. • Due to the perishability of the information, NearCasts requires numerical approaches that are extremely fast and notably different from those used in numerical weather prediction covering longer time periods. • The new Lagrangian approach to objective NearCasting optimizes the impact and retention of information provided by GOES satellites. • Designed to ingest and preserve extreme vertical and horizontal variations of moisture/temperature observed and updated by GOES • GOES data not currently used in NWP over land • Extremes are under-represented in conventional NWP analyses and forecasts. • Initial NearCasting products include 1-6 hour projections of the GOES multi-layer moisture observations, along with predictions of derived areas of convective destabilization. • Existing GOES sounder DPI products used as surrogate for GOES-R ABI • Discussions begun to test system using MeteoSat data • Being expanded to include other stability indices • Methodology directly transferable to GOES-R • Higher spatial/temporal resolution of ABI products will improve products further.
3. Motivation/Justification – Fundamentally unchanged from 2007 Review • Supports NOAA Mission Goals: Weather and Water, Commerce & Transportation, Homeland Security, Geostationary Orbiting Environmental Satellite Acquisitions • The Nearcasting System adds a short-range forecast component to GOES observations. • An area highlighted in the GOES-R3 program plan • According to the most recent version of the GOES-RRR Plan, Nowcasting applications developments (including the time-range of this project) was included throughout the life of the GOES-RRR program. • Although GOES multi-level DPI moisture observations have been shown to improve upon model first guesses and provide mesoscale detail not available from any other observing system, the data are not used over land in operational numerical forecast system. • As such, previous and ongoing investments in GOES satellites are being underutilized. • Uses the GOES moisture/temperature data at full resolution • The methodology used here is directly transferable to GOES-R ABI products • Although the value of GOES observations is eliminated after cloud formation occurs, the Nearcast System anticipates destabilization by dynamically projecting GOES multi-level products to future locations, independent of subsequent cloud development. • Provides evidence of need to support Geostationary Orbiting Environmental Satellite Acquisitions • The hourly-updated Nearcast output should help forecasters identify/isolate areas where severe convection is likely to occur 1-6 hours in advance. • Will reduce size of warning/watch areas, extend the lead time of watches/warnings, increase Probability of Detection and reduce False Alarms – Weather and Water and Homeland Security Goals • Especially useful for hard-to-forecast isolated summer-time convective events – Commerce and Transportation Goal (especially Aviation)
4. Methodology – Fundamentally unchanged (expanded) from 2007 Review How Lagrangian NearCasts work: An Example of “Convective Destabilization” Instead of interpolating randomly spaced moisture observations to a fixed grid (which smoothes the data) and then calculating moisture changes at the fixed grid points, the Lagrangian approach interpolated wind data to locations of GOES multi-layer moisture observations and then moves the full-resolution observed data to new locations, using the primitive equations to dynamically changing wind fields with ‘long’ (10 minute) time steps. . The moved moisture ‘obs’ values from each level are then both: 1) Transferred back to an ‘images’ for display and for use as ‘predicted DPIs’, and 2) Combined (subtracted) to identify meso-scale areas where Convective Instability will develop (where low-level moisture becomes capped by dry air aloft), even after convective clouds appear. Nearcast of Vertical Moisture Gradient (Convective Instability) (900-700 hPa GOES PW -700-500 hPa GOES PW) 3 Hour Nearcast : Valid 0000UTC 13 April 2006 – 2100 UTC 900-700 hPa GOES PW 0 Hour Ob Locations 13 April 2006 – 2100 UTC 900-700 hPa GOES PW 3 Hour Nearcast Image Verification Updated Hourly - Full-resolution 10 km data - 10 minute time steps
5. Summary of Previous Results – Expanded from 2007 Review • Efforts in previous years have used GOES-RRR Nowcasting and CIMSS resources to: • 1) In past years, • Developed and test the new Lagrangian-based dynamical Nearcasting Model, • Integrated GOES multi-layer DPI moisture data as a pre-curser for GOES-R ABI data, • 2) In current year, • Developed visualizations to depict predicted DPIs in formats identical to the observations. • This is critical for rapid assimilation of the Nearcast information during demanding forecasting situations • Efforts in current year include: indications of areas without data in past 6 hours, decreased confidence with time and revalidation as new data become available over time. • WFOs, NWS/CRH and NCEP/AWC agreed to participate in evaluations of the Nearcast products. • Validated need for this type of product and indicated areas for immediate application (especially AWC) • Evaluation sites prefer data in GRIB-II for use in AWIPS rather than as web-based imagery. • Required redirection of visualization efforts during past year to meet user requests. • Test Cases have demonstrated that: • Nearcasts expand the value of current and future GOES moisture products from observations to short-range forecasting tools • GOES DPI data can be inserted directly into model without “analysis smoothing’ • Nearcasts preserve observed data gradients, maxima and minima – image cycling maintains impact of past data • Stability information preserved as data projected into areas of subsequent cloud development • Nearcast Images agree well with lhe location and timing of storm formations and provide accurate/timely guidance, even after clouds have formed • System provides a fast, objective tool which increases the length of time that forecasters can make good use of detailed information from GOES products in their short range predictions • (vs. relying exclusively on smoother NWP output) Case of severe hail storm near Madison, WI Not predicted by operational NWP models
6. Expected Outcomes – Fundamentally unchanged from 2007 Review • If successful, WFO and NCEP Service Centers will improve their very-short-range forecasts and the GOES-R program office will have a series of examples showing how to maximize the benefit of temporal and spatial improvements available when GOES data are used effectively. 24 Hr Precip • Provide very-short-range, objective tools (NearCasts) to WFOs which will use existing DPI and future GOES-ABI products to: • Use projections of GOES multi-layer products to update NWP guidance • Identify areas of convective instability, even after cirrus outflow restricts the areas from being observed by GOES IR instruments. • Increase the length of time that forecasters can make good use of quality GOES observations which can supplement NWP guidance for their short range forecasts • Use GOES moisture/temperature products at full resolution • Preserve extreme horizontal and vertical gradients observed in GOES DPI products but missing in NWP • Improvements in spatial and temporal quality of GOES-R ABI will enhance products substantially • Hourly-updated NearCast output will help forecasters identify/isolate areas where severe convection is/is not likely to occur 1-6 hours in advance. • Products should be especially useful for hard-to-forecast isolated summer-time convective events – (especially important to Aviation operations) • Nearcasts of the pre-convective environment will allow forecasters to reduce the size of warning/watch areas, extend the lead time of watches/warnings, increase Probability of Detection and reduce False Alarms – (documented NWS Goals) • Nearcast products are scheduled to be tested initially in mid-western NWS/WFOs and AWC. • Based on positive tests and training, Nearcast Model products (and training materials) will be distributed to a broader set of NWS offices and made available to the private sector via the internet. 10 cm Hail Vertical Moisture Gradient (900-700 hPa - 700-500 hPa GOES PW) Forecast Information Lost under cirrus shield without NearCast
6. Expected Outcomes – Expanded from 2007 Review • Provide very-short-range, objective (nearcast) tools to WFOs which will use current and future GOES-ABI moisture/temperature products to: • Use projections of GOES multi-layer moisture/temperature products to update NWP guidance • Identify areas of convective potential, even after cirrus outflow restricts the areas from being observed by GOES IR instruments, using multiple Stability Parameters. • Increase the length of time that forecasters can make good use of quality observations which can supplement NWP guidance for their short range forecasts • Use GOES moisture/temperature products at full resolution • Preserve extreme horizontal and vertical gradients observed in GOES DPI products but missing in NWP Example of how forecasters will monitor, correct and locally enhance short-range NWP guidance for strong convection using projections of GOES moisture data which are available, even after the storms have begun. Nearcasts of GOES multi-layer moisture data show forecasters that NAM precip guidance: 1) Covers too much area, 2) Has major precip too far south, and 3) Shows no sign of local strong destabilization along WI-IL border, an area where major convection (4” hail) developed Case of severe hail storm near Madison, WI Not predicted by operational NWP models NAM 3 hour Precip Forecast valid 03 UTC 14 April 2006 - .2 cm interval color bands -

8. Funding Profile (K) – Unchanged from 2007 Review and Request • Summary of leveraged funding • Development phase funded in previous years through GOES-R Risk Reduction program, with NESDIS/ASPB supporting Bob Aune. • During evaluation phase, Bob Aune will continue to support this effort through NESDIS/ASPB and NWS evaluations will be support by individual WFOs • Nearcast methodology can be applied in NWS WFOs before launch of GOES-R – providing early benefit and enhancing utility of existing GOES satellites (as well as future GOES-R ABI products)

1. FY09 GOES-R3 Project Proposal Title Page • Title: Algorithm Development, Data Analysis and Visualization Capabilities for the GOES-R Program • Project Type: GOES utilization Proposal • Status: Ongoing • Duration: Year 2 of 3 years • Leads: • Tom Rink, Ray Garcia, • Other Participants: • Tom Whittaker, Mike Pavolonis, Tom Achtor, Bob Knuteson, Bruce Flynn
2. Project Summary • The intent of this proposal is to support the GOES-R program in the areas of algorithm development, data analysis and visualization by leveraging capability under development for the fifth generation McIDAS, an open source environment for scientists and application developers. • This proposal will transition new research and development concepts in visualization and high performance computing that have been funded at least in part by the NOAA Cooperative Agreement with CIMSS over the past several years into an integrated package that can be used by application developers and scientists working on the Risk Reduction and AWG teams. • The proposal is for a staged development of functionality that is of immediate benefit for the algorithm development and validation of the AWG development teams while building interfaces to the yet-to-be determined GOES-R ground system and GOES-R specific data types.
3. Motivation/Justification • Supports NOAA Mission Goal(s): Weather and Climate • This proposal addresses requirements outlined in the GOES-R Risk Reduction by providing NESDIS researchers and AWG developers • access to a broad spectrum of existing operational and research satellite data from both geostationary and polar orbiting platforms, • access to high performance computing environments for medium scale testing of algorithm performance of the large datasets planned for the GOES-R program, • access to external datasets for algorithm validation, • access to historical algorithms for algorithm verification and accuracy assessment, • access to state-of-the-art visualization tools built upon community standards. • The McIDAS-V platform is uniquely suited to algorithm testing and validation due to it’s ability to interface to the following critical datasets • the current GOES and POES sensor real-time and historical datasets (and algorithms) via ADDE and other servers and algorithms via the command line interface bridge to McIDAS-X, • the Proxy datasets for GOES-R derived from METEOSAT-SEVIRI and polar orbiting imagers and sounders (MODIS, AIRS and IASI), • simulated datasets of ABI and the future hyper-spectral sounder.
4. Methodology • The initial enhancements to the McIDAS-V open source development proposed for GOES-R risk reduction are • the custom integration of the CIMSS HYDRA visualization software package for use with GOES-R Proxy data and ABI simulation datasets, • the development of a command interface to NOAA’s GEOCAT algorithm development framework which is being used in the transition of algorithms from the AWG algorithm developers to the AWG Algorithm Integration Team. • This proposal falls into the Data Processing and Visualization category of the GOES-R risk reduction plan and as such will be managed as a software development project under the UW-SSEC quality assurance program.
5. Summary of Previous Results • The starting point of this proposal is a real, functional • McIDAS-V software package which integrates the visualization capabilities of the SSEC/CIMSS VisAD library as implemented by the Unidata Integrated Data Viewer (IDV) with a command line interface to the McIDAS-X system used for the current GOES program. • Current FY08 work: • The McIDAS-V/HYDRA integrated package has been extended to include data from the hyperspectral infrared IASI sounder on the operational polar platform METOP-A to facilitate Geo/Leo synergistic algorithm development. • Simulated ABI data from the AWG Proxy Team is now supported in the McIDAS-V/HYDRA environment. Examples follow.
6. Expected Outcomes • The HYDRA and GEOCAT integration into McIDAS-V will allow nearly anyone within the GOES-R program (scientists, researchers, software engineers, testers, and even managers) to easily find test datasets, run key algorithms, visually explore the results, and save the products in standard file formats for import into other applications; all accomplished from the users desktop. • GEOCAT running on a high performance computing cluster, via a customized McIDAS-V/GEOCAT interface will facilitate more interactive and experimental algorithm assessment with large datasets, and/or permutations of many single algorithm variations. • In the long term, this activity provides a clear transition path for NOAA NESDIS research and development from the very large code base developed over the past 30 years for the current GOES to new sensor data anticipated for GOES-R and beyond. A bridge from past to future is essential for training university students and re-training NOAA employees during the transition to the GOES-R era.
7. Major Milestones • FY08 • Integrate the HYDRA visualization package with McIDAS-V and test with GOES-R Proxy datasets (e.g. SEVIRI and MODIS) . • Release a distribution package for use with simulated ABI proxy datasets. • FY09 • Integrate a command interface to the GEOCAT application framework and develop the web service interface to cluster computing appropriate for taking advantage of distributed computing networks. • Release an updated distribution package which supports AWG algorithms • Support site installation of the enhanced McIDAS-V package for beta testing. • FY10 • Collect user feedback and priorities for future development. • Coordinate with the AWG teams on meeting their development needs. • Release an updated distribution package which addresses the user feedback information and supports additional AWG algorithms.
