The DC-8 dropsonde system uses an integrated, highly accurate, GPS-located atmospheric profiling dropsonde, which measures and records current atmospheric conditions in a vertical column below the aircraft. The dropsonde instrument is ejected from a tube in the underside of the DC8 aircraft. As the dropsonde floats to the surface on a parachute, it continuously measures and transmits via a 400 MHz meteorological band telemetry link, pressure, temperature and relative humidity, as well as GPS-based wind formation data, to the receiving system onboard the aircraft. Data was collected for the GRIP campaign from 17 Aug 2010 to 22 Sep 2010. Version 2 was not public.


GRIP Dropsonde data has been removed due to a dry-bias error. Corrections have been made in V3. More information can be found at: https://ghrc.nsstc.nasa.gov/uso/ds_details/inactive_docs/gripdrop1/Tech_Note_Dropsonde_Dry_Bias_20160527_v1.3.pdf
