In 1971, the National Weather Service (NWS) began The Digitized Radar Experiment (D/RADEX) to improve the operational use of radar data through computer processing. The primary purpose of D/RADEX was to demonstrate the utility of digital reflectivity data in weather forecasting operations; D-RADEX was programmed for automatic preparation of low level reflectivity and rainfall accumulation products. The early stages of D/RADEX involved four sites: Kansas City, MO; Oklahoma City, OK; Fort Worth, TX; and Monett, MO. Through its lifetime, many advanced meteorological and hydrological products were developed under D/RADEX including echo tops, vertically integrated liquid water content, severe weather probability, storm structure, and rainfall accumulation. In 1983, positive evaluation of the results of D/RADEX resulted in transferring the system to quasi-operational status and renaming it Radar Data Processor, version II (RADAP II). Data were collected from nine stations: Amarillo, TX, Wichita, KS, Charleston, WV, Garden City, KS, Limon, CO, Oklahoma city, OK, Pittsburgh, PA, Ruskin, FL and Monett, MO. The period of record began with April, 1985 data. The major data variables that make up this file are: station identification and time, elevation angle, range interval, merge data, elevation, type observation, rotational direction of original input data, ap indicator, snow indicator, number of data values, and number, mean, and standard deviation of non-zero DVIP values. This data file was collected and processed by the Oklahoma climatological survey of Norman, Oklahoma. To make a wide range of climatic data available to researchers and the public. completed DOC/NOAA/NESDIS/NCEI > National Centers for Environmental Information, NESDIS, NOAA, U.S. Department of Commerce Customer Engagement Branch 1-828-271-4800 1-828-271-4876 151 Patton Avenue Veach-Baley Federal Building, Room 468 Asheville NC 28801-5001 USA ncei.orders@noaa.gov https://www.ncei.noaa.gov HTTPS Web Browser NOAA National Centers for Environmental Information (NCEI) NCEI home page with information, data access and contact information. information 8:00 - 6:00 Eastern pointOfContact asNeeded Earth Science > Spectral/Engineering > Radar > Radar Reflectivity Earth Science > Atmosphere > Precipitation > Precipitation Amount Earth Science > Atmosphere > Precipitation > Solid Precipitation > Snow Earth Science > Atmosphere > Weather Events > Rain Storms Earth Science > Atmosphere > Precipitation > Liquid Precipitation > Rain Earth Science > Atmosphere > Precipitation > Solid Precipitation > Snow Earth Science > Atmosphere > Altitude > Station Height theme Global Change Master Directory (GCMD) Science Keywords 2018 revision Version 8.6 Global Change Data Center, Science and Exploration Directorate, Goddard Space Flight Center (GSFC) National Aeronautics and Space Administration (NASA) https://earthdata.nasa.gov/about/gcmd/global-change-master-directory-gcmd-keywords HTTPS Web Browser Global Change Master Directory (GCMD) Keywords The information provided on this page seeks to define how the GCMD Keywords are structured, used and accessed.

Each file contains one file of data for one RADAP II site. Each record has two logical parts representing one scan of data. Part 1 contains thirty-four 16 bit words of header parameters which describe the station and data characteristics for the scan (Table 2). Part 2 has a variable number of 16-bit words and contains the radial reflectivity category data for each scan in the form shown in Table 3. The RADAP II archive files can be read with a FAST FORTRAN I/O (FFIO) package subroutine called FFGET (BUF, N, L, &END, &ERR), where FFGET reads a record from FORTRAN unit "N" into contiguous locations starting at "BUF." The length of the record in bytes is returned in "L". At end-of-file (EOF), transfer will be made to statement number "END" and errors to statement number "ERR". Table 1 Nominal values of reflectivity thresholds for archived RADAP II data for base level scans for warm and cool seasons. The actual values used for a given archive scan are included in the header data for that scan. All tilt-sequence scans are archived with warm season category thresholds regardless of the season.
