Products from elevation angles at or below 3.5 degrees are available, and select sites may also scan at an additional low elevation angle, as low as -0.2 degrees. The same as N*R products defined above, except data values are actual reflectivity values instead of categories, data extends to further range, and additional elevations are available. Digital Base Reflectivity (NXQ, NYQ, NZQ, N0Q, NAQ, N1Q, NBQ, N2Q, N3Q/94) Sixteen possible data levels are also available. Four low elevation angles are available, with specific elevation angles depending on the scanning mode of the Radar. Scientists use these products to detect precipitation, evaluate storm structure, locate boundaries, and determine hail potential. Product Descriptionsīase Reflectivity (N0R, N1R, N2R, N3R/19 and N0Z/20)Ī display of echo intensity measured in decibels relative to Z (dBZ). Each copy includes state, county, and city background maps.

Most 元 products are available as digital images, color hard copy, grayscale hard copy, or acetate overlay copy. Over 75 Level-III (元) products are routinely available from NCEI. A data file consists of a 24-byte volume scan header record followed by numerous 2,432-byte base data and message records. Data are stored in files that typically contain four, five, six, or ten minutes of base data depending on the volume coverage pattern. Additional categories include dual-polarization base data of differential reflectivity, correlation coefficient, and differential phase. Level-II (L2) data are grouped into three meteorological base quantities: reflectivity, mean radial velocity, and spectrum width.

Request Offline Data Data Types NEXRAD Level-II (Base) Data This dataset is not currently available for direct download from NCEI, but is available by request from the offline archive.

An inventory of events is available here. An event summary file with descriptive information is included for each case study.

The data files have been aggregated by event and by hour for the archive with a total data volume of approximately 20 TB. The data files are in the native compressed file format as Time Series (TS) Archive. The number of case studies per year ranges from 1 to 33, with an average of approximately 10 per year. The period of record is from 2008 to present with additional data years planned. NEXRAD operational sites and test sites are used.

It includes only the Level 1 data that has been used for algorithm development and verification by the ROC and its partners. Please consult your device documentation for instructions.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. On mobile devices, you can save the bookmark as an easy-access icon similar to other apps.

For example, if you select 'Weather for a location,' then select a location, the bookmark will return to your location on your next visit. You may bookmark the URL to return later to the same view with the selected settings.

The URL will automatically update as you select the view and settings. This view is similar to a radar application on a phone that provides radar, current weather, alerts and the forecast for a location. This view combines radar station products into a single layer called a mosaic and storm based alerts. This view provides specific radar products for a selected radar station and storm based alerts. This site is organized into views that provide relevant radar products and weather information for a common task or goal.
