Brown, collected 16 February to 16 March 2016. 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 (). During January through March 2016, scientists led by the NOAA/Earth System Research Laboratory's Physical Sciences Division conducted NOAA's El Niño Rapid Response (ENRR) Field Campaign. Its goal was to document the ongoing El Niño episode in great detail, and in ways that could help researchers better understand the ways in which this El Niño affected weather in the United States and the impact of various high-resolution observations on weather forecasts. Intensive observations were collected over the central and eastern Pacific ocean from land, ocean, and airborne platforms during the very strong 2015-2016 El Niño. These data provide a high-resolution view of tropospheric and lower stratospheric conditions over the heart of the warm tropical Pacific during the late stages of the 2015-2016 El Niño. They are intended for use in meteorological, oceanographic, and biological studies of the east-central tropical Pacific during strong El Niño conditions. completed historicalArchive NOAA National Centers for Environmental Information ncei.info@noaa.gov https://www.ncei.noaa.gov/contact HTTPS NCEI Contact Information Information for contacts at NCEI. information pointOfContact asNeeded https://www.ncei.noaa.gov/access/metadata/landing-page/bin/gfx?id=gov.noaa.nodc:0161527 Preview graphic PNG 0161527 NCEI ACCESSION NUMBER 2017-02-09 publication AIR TEMPERATURE BAROMETRIC PRESSURE dew point RELATIVE HUMIDITY WIND DIRECTION WIND SPEED Wind speed - east-west component (U) Wind speed - north-south component (V) theme NODC DATA TYPES THESAURUS meteorological theme NODC OBSERVATION TYPES THESAURUS NOAA Ship Ronald H.
