SGP97: NWS High-Resolution Radiosonde Data
Summary
The Southern Great Plains 1997 (SGP97) 6-second National Weather Service (NWS) Soundings dataset contains high resolution sounding data extracted from NWS MicroART Sounding systems at 12 sites in the SGP97 domain. The dataset contains one sounding level every 6 seconds. These data have been extensively quality-controlled, with every sounding subjected to both computerized consistency checks and human visual review. This dataset includes pressure, temperature, dew point, relative humidity, wind speed, wind direction, and altitude. Please see the README for more details.
