This report contains a detailed description of a computer program that was developed for use with the Interdata 7/32 computer and the interfaced Nike Hercules radar systems located at the MTTR site at White Sands, New Mexico and the Poker Flat site in Alaska. The program can process in real-time a complete data reduction for an MRN rodketsonde or a list of 2 minute layer winds for a radiosonde. For a rocketsonde, the program utilizes the temperature telemetry data, the positional radar data, and the operator inputs of rocketsonde temperature calibration values and base level tie-in data from a radiosonde flight to produce an MRN(WDC-A) format listing of the following: 1 KM corrected and uncorrected winds; Significant level temperature data; 1 KM thermodynamic data; Significant level thermodynamic data; MRN 30 cards (image); Mandatory thermodynamic data; MRN 40 cards (image); and Printer plot of X and Y component winds and temperatures versus 1 KM altitudes. For a radiosonde, the program utilizes the positional radar data to produce a listing of two-minute layer winds at 1 minute intervals.
