A Super-Regional Modeling Testbed for Improving Forecasts of Environmental Processes for the U.S. Atlantic and Gulf of Mexico CoastsCyberinfrastructure
The ocean community needs a common cyberinfrastructure to access, analyze and display data from the different models: each model currently has their own standards and toolsets
Variety of Stretched
REST Request for catalog, can filter by time, geowindow, or parameter
PNG, or XML, or NetCDF
If Point Data, use ERDDAP base URL and allow users to see where points are, download data from all points for a time period, or select from a specific point to get data
If GRID Data, use Opendap URL or WMS to get images or time series data, or F-TDS to get regridded data or analysis.
JSON, CSV, XML, or other
*Web Client, Drupal, Matlab, ArcGIS, other…

Tropical Grids for Galveston Bay
Estuarine Hypoxia Chesapeake Bay
– 5 Hydrodynamic models
– 3 Biological (DO) models
– 2004 data from 28 CBP stations
– Comparing T, S, max (dS/dz), DO via target diagrams
2. Shelf: OBCs 5 hydrodynamic models
Models doing better on oxygen than stratification!
Shelf Hypoxia Gulf of MexicoHydrodynamic & biogeochemical hindcast comparisons of hypoxia model (stand alone) coupled to 3 different Gulf of Mexico hydrodynamics models
Evaluation of two shelf hypoxia formulations (NOAA & EPA)
Interactive Web Site
Web site where users can browse model results, view model grid data, side by side comparisons, extract time series, browse model and obs catalog, compare model and obs as time series
Unstructured Grid Support
Adding support for unstructured grids in the Java NetCDF libraries
Matlab-based toolbox to access the model data via njtoolbox and observation data
Matlab-based IMEDS toolbox to do “station” data comparisons for the inundation team.
Implement observation data as NetCDF on server connected to TDS and Catalog
Implementation of ERDDAP on server for different data delivery options .
Install and configure Ramadda for TDS harvesting
Implementation of F-TDS and LAS as services on the server for server-side model data regridding, analysis, and visualization.
Improvements to ncWMS for time-rounding, vectors.
Full view and detail of grid: eastward grid in red, northward grid in green. These are the original computation points on which the model outputs data.
Black diamonds are “Rho” grid points. Eastward points in red, northward points in green. Eastward and northward velocity model output have been translated to the RHO grid by the F/TDS script.
# Get the data from the F/TDS URL
# grab the rotated u,v and grid points. The grid
# is the same for both UBARROT and VBARROT
# Convert u and v to a complex for graphing
# plot the data
