This dataset contains the Level-I (L1) raw radar event data recorded at Next Generation Radar (NEXRAD) sites and collected by the NOAA National Weather Service (NWS) Radar Operations Center (ROC) for specific radar case studies. It includes only the Level 1 data that has been used for algorithm development and verification by the ROC and its partne...
Level-II (L2) data are grouped into three meteorological base quantities: reflectivity, mean radial velocity, and spectrum width. Additional categories include dual-polarization base data of differential reflectivity, correlation coefficient, and differential phase. Data are stored in files that typically contain four, five, six, or ten minutes of ...
Over 75 Level-III (L3) products are routinely available from NCEI. Most L3 products are available as digital images, color hard copy, grayscale hard copy, or acetate overlay copy. Each copy includes state, county, and city background maps. Note:Missing L3 data for Hurricane Ian were recently reprocessed and restored to archive. See the disclaimer f...

A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal.
One of the best features on the 88d Doppler radar is its ability to detect motion. However, the only motion it can "see" is either directly toward or away from the radar. This is called radial velocity as it is the component of the target's motion that is along the direction of the radar beam.
Learn about the different scanning modes of the Radar here. The ability to detect the "shift in the phase" of the pulse of energy makes NEXRAD a Doppler radar. The phase of the returning signal typically changes based upon the motion of the raindrops (or bugs, dust, etc.).
