El Niño Rapid Response (ENRR) Field Campaign: Radiosonde Data (Level 2) from NOAA Ship Ronald H. Brown, 2016-02 to 2016-03 (NCEI Accession 0161527)

These "Level 2" data have been reprocessed using corrected surface observations as initial conditions and then subject to automatic, objective quality control checks. The radiosondes were launched 4 to 8 times per day while the ship sailed from Honolulu, Hawaii to the Tropical Atmosphere Ocean (TAO) buoys along 140°W and 125°W and then to San Diego, California.

The data resolution within each sounding is 1 s. The following variables are reported: time since release (UTC); geopotential_height (m); air_pressure (hPa); air_temperature (C); dew_point_temperature (C); relative_humidity (%); eastward_wind (m s-1); northward_wind (m s-1); wind_speed (m s-1); wind_from_direction (degree); latitude (degree_north); longitude (degree_east); altitude (m); upward_platform_speed_wrt_ground (m s-1); geopotential_height status_flag (); air_pressure status_flag (); air_temperature status_flag (); dew_point_temperature status_flag (); wind status_flag (); GPS status_flag ().
