Presentation Transcript

  1. The NOAA Weather and Climate Toolkit Steve Ansari, Chad Hutchins, Stephen Del Greco (NOAA / NCDC) Mark Phillips (UNC-Asheville / NEMAC) Nina Stroumentova (STG Inc.)

  2. Overview • Free, public domain source code • Desktop and command-line application • Simple visualization and data export • Platform independent (Java-based) • Leverages community tools and standards (NetCDF for Java, Common Data Model, etc…) • Successor to Java NEXRAD Tools

  3. Access • Data: • Raw data files on disk or remote location (URL, THREDDS, OPeNDAP, etc…) • Services: • Easy to use dialogs for remote services distributed over web services (REST, WMS, WFS, OPeNDAP, NetCDF Subset Service, etc…)

  4. Data Currently: • NEXRAD (Level-II and Level-III) • GOES Satellite Coming soon: • GRIB, GINI, Generic NetCDF: • Feature types of Grid, Swath, Radial, Time Series, Point, etc…

  5. Services Currently: • U.S. Drought Monitor Coming soon: • Severe Weather Data Inventory • NOMADS (Model Data) • Climate Data Online • NEXRAD Mosaic Archive (RIDGE) • Multi-Sensor Precipitation Totals

  6. Data Access NEXRAD Radar Data from NCDC: http://www.ncdc.noaa.gov/nexradinv/ Tutorials Available!

  7. Data Access GOES Satellite Data from NOAA CLASS System: http://www.class.ncdc.noaa.gov Tutorials Available!

  8. Visualization • Simple 2-D maps • Basic overlays included (states, counties, etc…) • Background images from any OGC WMS • Shaded Relief, Topo Maps, Landsat, ext… • Save images and animations to Animated GIF, AVI, KMZ (Google Earth)

  9. Visualization GOES Infrared with Blue Marble Web Map Service (WMS) background map

  10. Visualization Smoothed NEXRAD Reflectivity Data

  11. Visualization GOES Full Disk Infrared

  12. Visualization U.S. Drought Monitor service from NIDIS/NDMC (National Drought Mitigation Center)

  13. Data Export • “Bridge” between raw Weather and Climate data and multiple scientific user communities • Export Data to: Shapefile, Well-Known Text, Arc/Info ASCII GRID, Gridded and Raw NetCDF, GeoTIFF and KMZ (Google Earth)

  14. Applications Level-II NEXRAD Reflectivity data from Hurricane Charley in ESRI ArcScene. Data exported to a point Shapefile with an exaggerated height attribute.

  15. Applications GOES Satellite Imagery from Hurricane Rita landfall in Google Earth

  16. Applications GOES Satellite Imagery from Hurricane Rita landfall, exported as ASCII GRID, in ArcGIS

  17. Applications Command-line batch processing of data export

  18. Applications Public domain / open source API
