How many WSR-88D radars are there?
How many WSR-88D radars are there?
160 WSR-88D radars
The Weather Surveillance Radar, 1988 Doppler (WSR-88D), also known as NEXRAD, is the most advanced operational weather radar in the world. The fleet of 160 WSR-88D radars operate 24/7 to support the weather warning and forecast missions of the National Weather Service, FAA and DoD.
How much does a WSR-88D radar cost?
It will cost over a million dollars to replace this WSR-88D. It costs over 20 million for a phased array radar.
What is the range of a nexrad WSR-88D when it transmits at 1304 Hz?
| Radar | PRF(pulses per sec) | Rmax(km) |
|---|---|---|
| WSR-57 | 164 or 545 | 915 or 275 |
| WSR-74C | 259 | 579 |
| WSR-88D | 318-1304 | 471-115 |
What is Level 3 radar data?
The Level 3 data consists of reduced resolution, low-bandwidth, base products as well as many derived, post-processed products. Level 3 products are recorded at most U.S. sites, though non-US sites do not have Level 3 products. There are over 40 Level 3 products available from the NCDC.
What is NEXRAD Level 2 radar?
Weather Radar (Level II) NEXRAD is a network of 160 high-resolution Doppler weather radars operated by the NOAA National Weather Service (NWS), the Federal Aviation Administration (FAA), and the U.S. Air Force (USAF).
How much does a NEXRAD radar cost?

What is Nexrad Level 2 radar?
How much is a Nexrad radar?
What is the difference between base and composite radar?
What is the difference between base and composite reflectivity? Base reflectivity only shows reflected energy at a single elevation scan of the radar. Composite reflectivity displays the highest reflectivity of ALL elevations scans.
How far can a Doppler radar reach?
The National Weather Service’s 148 WSR-88D Doppler radars can detect most precipitation within approximately 90 mi of the radar, and intense rain or snow within approximately 155 mi. However, light rain, light snow, or drizzle from shallow cloud weather systems are not necessarily detected.
What type of information can you learn from looking at Doppler radar images?
Information on the movement of objects either toward or away from the radar can be used to estimate the speed of the wind. This ability to “see” the wind is what enables the National Weather Service to detect the formation of tornados which, in turn, allows us to issue tornado warnings with more advanced notice.
How do I get NEXRAD data?
NEXRAD data can be accessed through the following data access services:
- NEXRAD Inventory. A search and discovery hub for NEXRAD data that hosts a variety of data access tools, statistics, and documentation.
- Climate Data Online. Use Climate Data Online (CDO) Search for data by county, city, and zip code.
- Radar Map.
