GPM Ground Validation Advanced Vertical Atmospheric Profiling System (AVAPS) OLYMPEX V1

Published by NASA/MSFC/GHRC | National Aeronautics and Space Administration | Metadata Last Checked: August 10, 2025 | Last Modified: 2025-08-06
The GPM Ground Validation Advanced Vertical Atmospheric Profiling System (AVAPS) OLYMPEX dataset contains dropsonde vertical profiles of atmospheric pressure, air temperature, dew point temperature, relative humidity, wind direction and magnitude, and sensor location obtained during the Olympic Mountains Experiment (OLYMPEX). The AVAPS dropsondes were released during specific NASA DC-8 aircraft flights between November 12, 2015 and December 19, 2015. A total of 53 standard research dropsondes were launched in the Pacific ocean off the coast of Washington state collecting atmospheric profile observations. The AVAPS datasets are available in ASCII-eol text format.
