Near real-time data from the Suomi-NPP satellite's VIIRS instrument provides global nighttime sea surface temperature (NSST) estimates. The dataset includes variables for sea surface temperature in degrees Celsius and associated quality flags. Nighttime observations are used to minimize diurnal warming and sun glint for detecting ocean fronts and supporting climate analyses.
VIIRS, the successor to MODIS on the Suomi-NPP satellite, provides sea surface temperature retrieved with a specialized triple-window thermal-infrared algorithm for improved atmospheric correction. The instrument's 22 spectral bands, including 16 moderate-resolution and 5 high-resolution imaging bands, support multi-disciplinary Earth observation. This Level-3 global mapped product specifically delivers SST data corrected for water-vapor effects using three atmospheric windows near 8.6 µm, 11 µm, and 12 µm.
Data collection from the TES instrument aboard NASA's Aura satellite, launched July 15, 2004, is complete. The Level 1B product contains radiometrically calibrated spectral radiances, noise equivalent spectral radiances (NESR), geolocation, and quality data from special observation modes. These calibrated spectra serve as the primary input for retrieving atmospheric species profiles, temperature, and surface parameters.
Aircraft in situ meteorology, navigation, and trace gas data collected during the NASA TRACE-A suborbital campaign. The dataset originates from 19 instruments aboard a NASA DC-8 aircraft, which flew missions over the Atlantic Ocean from September 21 to October 24, 1992. The campaign aimed to determine the source of high ozone concentrations between southern Africa and South America.
NASA's SOLVE campaign deployed a DC-8 aircraft to collect in-situ aerosol data for validating the SAGE III satellite. The dataset includes particle size spectra from instruments like the FSSP, PCASP, CNC, FCAS II, and N-MASS.

Global satellite observations from NASA's Aura spacecraft provide vertical profiles of deuterium oxide (heavy water vapor) in the troposphere. The data product contains retrieved species volume mixing ratios, temperature profiles, surface temperature, and associated diagnostic quantities like precision and vertical resolution for each of up to 3,200 retrievals per two-day global survey. Measurements were collected via the Tropospheric Emission Spectrometer (TES) instrument, which operated from its launch on July 15, 2004, until data collection was completed.
AVIRIS-NG imagery from 2021 was processed using linear spectral unmixing to estimate fractional cover of green vegetation, non-photosynthetic vegetation, and soil across the Atchafalaya and Terrebonne basins in Louisiana. The analysis combined airborne hyperspectral data with in situ field spectra from the USGS Spectral Library (v7) and ground-level GoPro images. Outputs provide pixel-level fractional composition values scaled from 0 to 1.
NASA's FLEXPART Influence Functions dataset contains Lagrangian particle dispersion simulations quantifying carbon dioxide source-receptor relationships. The data were generated for five ACT-America airborne campaign deployments over the eastern United States between 2016 and 2019. Simulations track 5,000 particles backward from flight track intervals, driven by 27-km WRF-Chem or ERA-Interim meteorology.
A dataset analyzing national attention to climate change using the Google Trends search intensity index for the terms 'climate change' and 'global warming'. The data is structured at the state-month-year level for Australia between 2008 and 2020, following extreme weather events identified via the Australian Disaster Resilience Knowledge Hub. It was created by Christopher Crellin and is available under a CC-BY-4.0 license.
Particle size spectra data were collected to validate satellite observations for the Global Precipitation Measurement mission. The National Aeronautics and Space Administration gathered measurements from the Cloud spectrometer and impactor and a 2D-S probe aboard the University of Wyoming King Air aircraft. The dataset covers a campaign in Finland from August to October 2010.
