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 released 2 times per day from (2.01°N, 157.40°W). 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 near-equatorial waters during the late stages of the 2015-2016 El Niño. They are intended for use in meteorological, oceanographic, hydrologic, and biological studies of the central equatorial 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:0161525 Preview graphic PNG 0161525 NCEI ACCESSION NUMBER 2017-02-09 publication AIR TEMPERATURE 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 Earth System Research Laboratory dataCentre NODC COLLECTING INSTITUTION NAMES THESAURUS NOAA Earth System Research Laboratory dataCentre NODC SUBMITTING INSTITUTION NAMES THESAURUS meteorology oceanography theme WMO_CategoryCode 2012-09-15 publication DOC/NOAA/OAR/ESRL/PSL > Physical Sciences Laboratory, Earth System Research Laboratory, OAR, NOAA, U.S. Department of Commerce dataCentre Global Change Master Directory (GCMD) Data Center Keywords 2026 revision 24 Earth Science Data and Information System, Earth Science Projects Division, Goddard Space Flight Center (GSFC), National Aeronautics and Space Administration (NASA) Greenbelt MD https://forum.earthdata.nasa.gov/app.php/tag/GCMD%2BKeywords HTTPS GCMD Keyword Forum Page Global Change Master Directory (GCMD). 2025.
