Visualization of NEXRAD Reflectivity sweeps and derived isosurfaces in Google Earth for the May 22, 2011 Joplin, MO tornado. The image was generated with the NOAA Weather and Climate Toolkit and Google Earth.
Radar, an acronym for radio detection and ranging, is an object detection system that uses radio waves to determine the range, altitude, direction of movement, and speed of objects. The antenna transmits pulses of radio waves or microwaves, which bounce off any object in their path. The object returns a tiny part of the wave's energy to a dish or antenna. For more information, please refer to the Introduction To Doppler Radar and Radar FAQ, produced by NOAA's National Weather Service.
NCEI's Radar Archive includes the Next Generation Weather Radar System (NEXRAD) and Terminal Doppler Weather Radar (TDWR) networks. The NOAA Radar Operations Center provides centralized meteorological, software, maintenance, and engineering support and documentation.
Download radar data at no cost from NCEI or order a hardcopy of radar maps for a small fee.

- Radar Data in the NOAA Big Data Project
All Level-2 NEXRAD Radar data is currently available in cloud infrastructures.
- Next Generation Weather Radar (NEXRAD)
Information on the NEXRAD network, history, documentation, base data, and derived products.
- Terminal Doppler Weather Radar (TDWR)
Information on the TDWR network, history, documentation, and derived products.
- Radar Display and Conversion Tools
Radar data is in a custom binary format. The visualization and decoding of the data requires specialized software.
- Interactive Radar Map Tool
Supplemental data in support of the radar archive, including historical five-minute reflectivity mosaics for the continental United States, radar coverage maps, and map-based site selection tools.
- Severe Weather Data
Several severe weather datasets exist including the Severe Weather Data Inventory (SWDI), Lightning Products and Services, Storm Data, and International Best Track Archive for Climate Stewardship. SWDI contains a database of the NEXRAD/TDWR tracked storm attributes, including storm structure, hail, mesocyclone, and tornado vortex signature.

Interactive Map Tool
Radar Geographic Information Systems (GIS) Interactive Map. Click on the map to view this tool.
The Interactive Radar Map Tool shows supplemental data in support of NCEI's Weather Radar Archive. The tool includes several unique features that will allow the user to select data from 1995 to present for individual or multiple stations at varying altitudes.
Historical Reflectivity Mosaics
The map tool utilizes the Reflectivity Mosaics products and web services provided by the Iowa Environmental Mesonet. Reflectivity is available from 1995 to near-real time in five-minute increments. The raw data are not available for download and are only accessible as images on this map or from the Iowa Environmental Mesonet.
This version requires the Flash browser plugin.
Range and Coverage of Radar Sites
The typical range of most radar products is 230 km from the radar site. However, mountains can block the lower sweeps of the radar beam in certain parts of the country. The Interactive Radar Map Tool provides map layers, which show the maximum distance (230 km), as well as maps derived from geospatial models, which determine areas where the mountains block the beam. The analysis, conducted by NOAA's Radar Operations Center, shows the availability of beam coverage at specified altitudes from the ground. The map tool includes layers at 4,000 (best coverage), 6,000 (better coverage), and 10,000 (fair coverage) feet.
Please contact NOAA's Radar Operations Center for more information on how the coverage products are calculated.
The map tool includes selection tools, which allow users to select individual or multiple sites and begin the ordering process for historical data in NCEI's Radar Data Archive.
MyRadar Weather Radar for Android
MyRadar is a very detailed application that presents radar maps brilliantly and processes quickly to give you on-demand results. Although some of the better features offered are only available for purchase, there are just enough options on hand to make this a helpful and easy-to-use program.
Prompt and reliable: We observed that all radar maps loaded within a few moments after navigating to a specific region, and the weather animations always played smoothly. We also experienced no stability issues, likely because the 3.0.10 update improved overall performance.
Uncomplicated usability: MyRadar's display is very clear-cut and does not contain many buttons, which is great because it presents you with a large map and few distractions. It's also helpful that all menus only present necessary information in a concise manner, making your experience much easier.
An assortment of features:Various settings, such as the Flight Plan display, are available to make a radar map customized just for you. The GPS tool, which was made more accurate in the latest update, always performed well, and the variety of fine-tuning options, such as cloud opacity, are small yet influential.
Lack of coverage: MyRadar only offers weather coverage for the continental United States, possibly because of a reliance on National Weather Service information, which fairly hinders overall effectiveness.
For general weather radar monitoring, MyRadar is an excellent application to use. Pilots and others that are interested in live weather radar should find this an effective and enjoyable program.
