MERRA-2 is a global atmospheric reanalysis produced by NASA's Global Modeling and Assimilation Office (GMAO) using the GEOS model. The dataset covers the period from 1980 to the present with a latency of approximately three weeks after the end of a month. It provides assimilated meteorological fields, such as temperature, wind, and water vapor, across 72 model layers at a 0.625 x 0.5-degree resolution every three hours.
MERRA-2 M2I3NPASM is an instantaneous 3-dimensional, 3-hourly meteorological assimilation dataset produced by NASA's Global Modeling and Assimilation Office (GMAO). It contains assimilated fields such as temperature, wind components, and water vapor across 42 pressure levels, covering the period from 1980 to the present with a latency of approximately three weeks. The data is generated using the Goddard Earth Observing System Model (GEOS) version 5.12.4.
M2I3NVAER (inst3_3d_aer_Nv) is a 3-dimensional, 3-hourly instantaneous data collection from NASA's MERRA-2 global atmospheric reanalysis. The dataset contains assimilations of aerosol mixing ratios for dust, sulphur dioxide, sea salt, black carbon, and organic carbon across 72 model layers. It is produced by NASA's Global Modeling and Assimilation Office (GMAO) using the GEOS model and covers the period from 1980 to the present.
NSIDCV0 provides land use classification data derived from Landsat 5 satellite imagery for the Soil Moisture Experiment 2003 (SMEX03). The dataset is focused on the Oklahoma study region. It was created for the 2003 experiment, with metadata updates recorded as recently as 2026.
Landsat 5 Thematic Mapper satellite imagery was processed for analyzing land cover features during the Soil Moisture Experiment 2003 (SMEX03) in Georgia, USA. The dataset is provided by the National Snow and Ice Data Center (NSIDCV0). Imagery was collected and processed around July 2003.
Radar backscatter measurements were collected over the Walnut Creek Watershed in Iowa during the Soil Moisture Experiments 2002 (SMEX02). The dataset contains airborne synthetic aperture radar (AIRSAR) data. It is provided by the NSIDC and was collected in 2002, with metadata last updated in 2006.
Browse images were acquired over Alabama, Georgia, and Oklahoma as part of the 2003 Soil Moisture Experiment. The dataset originates from the ENVISAT ASAR instrument and is provided by the NSIDCV0 organization. Data files are available in BIN, ISO, and HTML formats.
Arctic measurements of stratospheric composition were collected from November 1999 to March 2000. The Lidar Atmospheric Sensing Experiment (LASE) aboard NASA aircraft produced vertical profiles of aerosols and water vapor from 6-8 km down to the surface. This data was gathered by NASA during the SAGE III Ozone Loss and Validation Experiment (SOLVE) campaign to validate satellite measurements and study polar ozone processes.
2003 data provides brightness temperature measurements from the SSM/I sensor collected during the Soil Moisture Experiment 2003 (SMEX03) in Oklahoma. The dataset is managed by the National Snow and Ice Data Center (NSIDC). It supports research into soil moisture retrieval and land surface modeling.
ThetaProbe ML2 sensor data was collected for the Soil Moisture Experiment 2003 (SMEX03) in Alabama. The dataset is managed by the NSIDCV0 organization. It is available on multiple platforms, including NASA Earthdata and Data.gov.
February 1 to March 15, 1992 upper air data collected from surface and aircraft sites during the STORM-Fronts Experiment Systems Test. The dataset consists of quality-controlled soundings interpolated to 10 mb pressure levels, compiled by SCIOPS. Parameters include launch times, station location, pressure, temperature, humidity, wind components, altitude, and quality control flags.
Modeled snow water equivalent data for 10 mountain ranges in North America, simulated by the Weather Research and Forecasting regional climate model. The dataset is produced by the NSIDCV0 organization and is available across multiple data platforms, indicating established use. The most recent metadata update was recorded in March 2026.
Browse images from the ENVISAT Advanced Synthetic Aperture Radar (ASAR) instrument were collected over Alabama, Georgia, and Oklahoma as part of the 2003 Soil Moisture Experiment (SMEX03). The dataset is provided by the National Snow and Ice Data Center (NSIDC) and focuses on regional study areas in the United States. Data acquisition occurred during the 2003 experiment campaign.
SMEX03 ENVISAT ASAR browse images provide a visual index of radar backscatter data collected during the 2003 Soil Moisture Experiment. These geospatial images cover three distinct regional study areas in the southeastern and central United States. The dataset serves as a reference for locating and interpreting quantitative radar measurements of land surface conditions.
SMEX03 Site Photographs consist of images captured during the 2003 Soil Moisture Experiment (SMEX03) across regional study areas in Alabama, Georgia, and Oklahoma, USA. The dataset documents ground conditions for the NASA-led experiment. It is managed by the NSIDCV0 organization.
NOAA AVHRR satellite data provides landfast sea ice coverage and variability along the Adelie Land coast in East Antarctica. The dataset includes 881 cloud-free AVHRR images selected from 10,297 processed scans, covering the period from 1992 to 1999. AU_AADC compiled the data, derived from NOAA AVHRR and other satellite imagery.
Current meter components data were collected from fixed platforms in the Northeast Pacific Ocean from July 8, 1982, to October 1, 1985. The dataset contains time-series measurements of east-west (u) and north-south (v) current vector components, representing Eulerian flow measurements at specified sensor depths. Water temperature, pressure, and conductivity or salinity may also be reported at 10-15 minute intervals.
Rosenstiel School of Marine and Atmospheric Science collected these Eulerian current measurements from fixed moorings along the North American Coastline-South for over eight months in 1979. The data, processed into the NODC F015 standard format, likely contains time-series records of east-west (u) and north-south (v) current vector components, typically at 10-15 minute intervals. Position, sensor depth, and optional water temperature or salinity may also be reported for each station.
January 1982 to present monthly land surface parameters simulated by the Noah 3.6.1 model within the Famine Early Warning Systems Network (FEWS NET) Land Data Assimilation System (FLDAS). The data are at 0.10 degree resolution with global spatial coverage (60S, 180W, 90N, 180E). The simulation was forced by a combination of MERRA-2 and CHIRPS data and is produced by the National Aeronautics and Space Administration.
VIIRS, a 22-band radiometer on the Suomi NPP satellite launched in 2011, provides this global sea surface temperature dataset. The dataset offers near-daily coverage with a spatial resolution of 750 meters at nadir, constrained to no more than 1600 meters at the swath edge. Each netCDF file contains 768 x 3200 pixels of temperature data at a 1-meter depth, processed in compliance with GHRSST GDS version 2 specifications.
