Top of Page Download Data From NCDC Archive

The Archive of WSR-88D NEXRAD Radar Data is stored on the NCDC Robotic Mass Storage System, commonly known as the Hierarchical Data Storage System (HDSS). Data is available from 1991 to 1 day from present. The data is easily accessable with the NEXRAD Inventory Search tool. This tool allows users to view the data completeness and download data. The ordered data is ready for use with the NCDC Java NEXRAD Viewer and Data Exporter. Each order may contain up to 24 hours of data at a time for a single site.

The data may also be ordered from the NCDC HDSS Access System (HAS) web page . This is a better option for users needing large amounts of data in the tar archive format. Up to a week of data for multiple sites may be ordered. A 5-Minute HAS Tutorial is available to guide users downloading nexrad data.

The NEXRAD sites may be viewed in 3D Earth browsers (such as Google Earth) using this KML file: nexrad.kmz (8KB)



Top of Page Visualize Radar Data

Downloaded Radar Data is in a unique digital binary format. Special software must be used to visualize the data. Several free visualization and analysis products are available for download.

NCDC Radar Software

The NCDC Java NEXRAD Viewer is Java(TM)-based software which visualizes WSR-88D Level-II and Level-III NEXRAD Radar data from the NCDC Archive. The Java NEXRAD Data Exporter allows the export of NEXRAD data to common scientific formats such as Shapefile, Arc/Info ASCII Grid and more.


Unidata Software

The Integrated Data Viewer (IDV) from Unidata is a Java(TM)-based software framework for analyzing and visualizing geoscience data. The IDV brings together the ability to display and work with satellite imagery, gridded data, surface observations, balloon soundings, NWS WSR-88D Level II and Level III Radar data, and NOAA National Profiler Network data, all within a unified interface.


NSSL/CIMMS Software

The Warning Decision Support System -- Integrated Information (WDSS-II) is the second generation of a suite of algorithms and displays for severe weather analysis, warnings and forecasting. Extensive C++ API, 3D analysis, data mining, real-time algorithms and storm tracking capabilities. Linux platform only.






Top of Page Real-Time Radar Data

Real-Time Level-III images and data are available from the National Weather Service.

Real-Time Level-III data may be downloaded from:
http://www.nws.noaa.gov/tg/rpccds.html.

Real-Time Level-III images are available at:
http://www.crh.noaa.gov/radar/national.html.

Other Real-Time Level-III Radar Images may be found at NCDC's List of External Radar Resources.

Level-II data is also available in real-time. Please read the NOAA Press Release for more information.



Top of Page Storm Events Database

The Storm Events Database provides descriptive information about severe weather events beginning in 1950. This tool can be used to search for severe weather events such as tornados, hurricanes, floods, lightning and hail. The Storm Events Database can aide in the search for interesting and/or event specific radar data.
