Weather Radar Data Services at NOAA's National Climatic Data Center
Stephen Del Greco, May 29, 2012
Radar Archives & Access• NCDC has been up to the WSR‐88D challenge (Tim’s words)
• Amount of “uncompressed” radar data at NCDC, available to users/requestors• Level 2: 2,099 TB or 2.1 PB• Level 3: 94.7 TB
• Amount of Level 3 data archived/yr has increased six‐fold from 2 TB in 2008 to 11.4 TB in 2012
• Level 2 and Level 3 data ordered/accessed more than doubled between 2011 and 2012• Level 2: 69 TB in 2011, 158 TB in 2012• Level 2: 41 TB in 2011, 108 TB in 2012
• Level 2 median retrieval latency ~6 min in 2011

Radar Archives & AccessRadar Data Services• Direct digital access to radar inventories, data, and visualization software are available
at no cost via the NCDC radar resources web page, (http://www.ncdc.noaa.gov/oa/radar/radarresources)

Weather and Climate Toolkit (WCT)• WCT is free, platform independent software distributed from NOAA’s NCDC. • The WCT allows the visualization and data export of weather and climate data,
including Radar, Satellite and Model data. • By leveraging the NetCDF for Java library and Common Data Model, the WCT is
scalable and capable of supporting many new datasets. • Gridded NetCDF files (using Climate-Forecast (CF) conventions) are supported,
along with many other formats. • The WCT provides tools for custom data overlays, Web Map Service (WMS)
background maps, animations and basic filtering.
Weather and Climate Toolkit (WCT)• The export of images and movies is provided in multiple formats.
• The WCT Data Export Wizard allows for data export in both vector polygon/point (Shapefile, Well‐Known Text) and raster (GeoTIFF, ESRI Grid, Gridded NetCDF) formats.
• These data export features promote the interoperability of weather and climate information with various scientific communities and common software packages such as ArcGIS, Google Earth, MatLAB, etc…
• The WCT also supports an embedded, integrated Google Earth instance.
• The Google Earth Browser Plug‐in allows seamless visualization of data on a native 3‐D Google Earth instance linked to the standard 2‐D map.
• Additional features include 3D rendering of Radar sweeps in Google Earth through the use of the COLLADA modeling technology
Networks Supported
NEXRAD, TDWR ( LVL III), Satellite, Model• Data Formats include:
• Gridded NetCDF, HDF and OPeNDAP• GRIB version 1 and 2• NEXRAD Level‐II• NEXRAD, TDWR Level‐III• GOES AREA Files• GINI• GEMPAK Grids• XMRG MPE
Applications• 3D Radar Sweeps in Google Earth:
– Drapes rendered image on COLLADA model
Applications• 3D Isosurfaces in Google Earth:
– Output of 3D Polygons to KMZ• Supported for Generic Radial, Level‐II NEXRAD and Gridded x, y, z datasets.

Summary
• Long way from archives of WSR‐57 and 74C 16mm screen captures • Advances in the amount and ease of access of real‐time and archive
WSR‐88D Level 2 and Level 3 data, then TDWR Level 3, have been steady and ongoing• Collaborative efforts with NEXRAD agencies, universities, private sector,
Unidata, and other organizations have leveraged resources and expertise• Continued support from Univ. of Oklahoma, Purdue Univ., Educational
Research Consortium of the Carolinas, and Unidata to make real‐time Level 2 data widely available
• NCDC • Tremendous partner in keeping pace with the amount and various types
of radar data• More data sets may be added • Superb customer service in reducing data access costs and time;
development of shareware for data display (Weather &Climate Toolkit)
