The CAR BRDF datasets have received additional processing beyond the L1C products, and include data for bidirectional reflectance factors at the full range of zenith and azimuth angles and the estimated surface-atmosphere albedo. Data and documentation is currently available for the following NASA CAR missions:


NASA's Global Hydrometeorology Resource Center Distributed Active Archive Center (GHRC DAAC) published two datasets from the Global Precipitation Measurement Ground Validation (GPM-GV) Iowa Flood Studies (IFloodS) field campaign, that took place from April 23, 2013 through June 30, 2013. The IFloodS field campaign was a ground measurement campaign that took place in eastern Iowa. The goals of the campaign were to collect detailed measurements of precipitation at the Earth’s surface using ground instruments and advanced weather radars and to simultaneously collect data from satellites passing overhead.

  • GPM0GV Naval Research Laboratory (NRL) Near Real-Time Rain Rates IFloodS was produced using the Probability Matching Method with rain gauge, Defense Meteorological Satellite Program (DMSP) F15 Special Sensor Microwave/Imager (SSM/I), and DMSP F16 Special Sensor Microwave Imager/Sounder (SSMIS) data. This data product includes rain rate estimates and files are available in netCDF-4 and binary formats, as well as corresponding browse imagery in JPG format.
  • GPM-GV Goddard Profiling Algorithm (GPROF) 2014 IFloodS dataset consists of precipitation data derived from microwave radiometers and sounders located on multiple satellites, including the DMSP F16-18, the Global Change Observation Mission – Water "Shizuku" (GCOM-W1), the European Space Agency's (ESA’s) Meteorological Operational satellite programme (MetOp) series, and NOAA's Polar Operational Environmental Satellites (POES) series. These data were specially produced by the Precipitation Measurement Missions (PMM) for IFloodS, using consistent processing and calibration. The GPROF 2014 data files are available from March 31 to July 2, 2013 in HDF-5 format.

NASA's Global Hydrology Resource Center Distributed Active Archive Center (GHRC DAAC) published the Tropical Cyclone Intensity (TCI) Hurricane Imaging Radiometer (HIRAD) dataset. This dataset was created for the TCI field campaign from August 30, 2015 through October 23, 2015. The goal of the TCI field campaign was to improve the prediction of tropical cyclone (TC) intensity and structure change. The specific focus was to have an improved understanding of TC upper-level outflow layer processes and dynamics. These HIRAD data were obtained from the instrument aboard the NASA WB-57 aircraft flow on specific dates during the campaign. The data files include brightness temperature, rain rate, wind speed, and sea surface temperature estimates in netCDF-3 format, with corresponding browse imagery in PNG format.

NASA's National Snow and Ice Data Center DAAC (NSIDC DAAC) has published the dataset IceBridge Narrow Swath ATM Level 1B (L1B) Elevation and Return Strength with Waveforms. This dataset contains spot elevation measurements with corresponding waveforms of Antarctic sea ice. The data were acquired by NASA's Airborne Topographic Mapper (ATM) narrow-swath instrumentation between 29 October 2017 to 22 November 2017 as part of aircraft survey campaigns funded by Operation IceBridge.

NASA's National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) released nine datasets, including:


NASA's Oak Ridge National Laboratory DAAC (ORNL DAAC) published the Atmospheric Tomography Mission (ATom) dataset, ATom: Aircraft Flight Track and Navigational Data. This dataset provides flight track and aircraft navigation data from ATom. Flight track information is available for the four ATom campaigns. Each ATom campaign consists of multiple individual flights and flight navigational information is recorded in 10-second intervals. Data available for each flight includes research flight number, date, and start and stop time of each 10-second interval. In addition, latitude, longitude, altitude, pressure and temperature is included at each 10-second interval. The ATom campaign deploys an extensive gas and aerosol payload on NASA's DC-8 aircraft for systematic, global-scale sampling of the atmosphere, profiling continuously from 0.2 to 12 km altitude. ATom establishes a single, contiguous, global-scale dataset. One intended use of this flight track data is to facilitate to mapping model results from global models onto the precise ATom flight tracks for comparison.

NASA's Oak Ridge National Laboratory DAAC (ORNL DAAC) published the Arctic-Boreal Vulnerability Experiment (ABoVE) dataset, ABoVE: Directory of Field Sites Associated with 2017 ABoVE Airborne Campaign. This dataset provides a listing of the approximately 6,700 field sites used in planning the ABoVE Airborne Campaign (AAC) for 2017. The sites included point, polygon, and line locations that were used in determining the 2017 AAC flight paths. We intend this compilation to assist investigators in understanding the flight line choices and as a method for investigators to identify ground locations used in the airborne campaign. Data users may also search for the underlying data available at each of these locations. Site descriptors include name, coordinates, principal investigators with emails, data types, long-term archive locations, and links to project descriptions.

ORNL DAAC published the ABoVE dataset, ABoVE: Permafrost Measurements and Distribution Across the Y-K Delta, Alaska, 2016. This dataset provides field observations of thaw depth and dominant vegetation types, a lidar-derived elevation map, and permafrost distribution and probability maps for an area on the coastal plain of the Yukon-Kuskokwim Delta (YKD), in western Alaska, USA. Field data were collected during July 8-17, 2016, to parameterize and to validate the derived permafrost maps. These high-resolution permafrost maps support landscape change analyses and assessments of the impacts of climate change on permafrost in this region of high biological productivity, critical wildlife habitats, and subsistence-based human economy.

ORNL DAAC published the North American Carbon Program (NACP) dataset, Stocks of Surface Soil Organic Carbon Fractions, Great Plains Region, USA, 2007-2010. This dataset provides estimates of total organic soil carbon (SOC), pyrogenic (PyC), particulate (POC), and other organic soil carbon (OOC) fractions in 473 surface layer soil samples collected from stratified-sampling locations in Colorado, Kansas, New Mexico, and Wyoming, USA. Terrain, climate, soil, fire, and land cover data used to predict and map SOC, PyC, POC, and OOC at 1 km resolution throughout the study region are also included. The estimates were derived using a best random forest regression model and cover the period 2007-05-01 to 2010-10-01.

ORNL DAAC published the Atmospheric Tomography Mission (ATom) dataset, ATom: Nucleation Mode Aerosol Size Spectrometer Calibration and Performance Data. This dataset provides extensive calibration and in-flight performance data for two nucleation mode aerosol size spectrometer (NMASS) instruments utilized in ATom. Each NMASS has five condensation particle counters (CPCs) that detect particles above a different minimum size, determined by the maximum vapor supersaturation encountered by the particles. Operated in parallel, the CPCs provide continuous concentrations of particles in different cumulative size classes between 3 and 60 nm. Data provided include: NMASS counting efficiencies and diameters of calibration aerosols, inverted particle size distributions; comparisons of NMASS and Scanning Mobility Particle Sizer (SMPS) results; and performance at flows, temperatures, and pressures measured by both NMASSs and comparison with Ultra-High Sensitivity Aerosol Spectrometer (UHSAS) concentrations collected aboard NASA's DC-8 aircraft during an ATom flight in February 2017.

ORNL DAAC published the ATom dataset, ATom: Black Carbon Mass Mixing Ratios from ATom-1 Flights. This dataset provides black carbon (BC) mass mixing ratios (in units of ng BC / kg air) measured during the ATom-1 flight campaign during July and August 2016. The BC-core masses of BC-containing aerosol particles were measured using a Single Particle Soot Photometer (SP2). Conversion to mass mixing ratio (MMR) is achieved by monitoring sample flow. Influences in air mass composition were determined using the Particle Analysis by Laser Mass Spectrometry (PALMS) instruments. Also included here are data from the Cloud, Aerosol and Precipitation Spectrometer (CAPS) instrument which are used to identify measurements taken while in clouds. Finally, the associated latitude, longitude, altitude, and the timestamp of each measurement are included. All data are at ten seconds resolution. ATom-1 flights originated from the Armstrong Flight Research Center in Palmdale, California, fly north to the western Arctic, south to the South Pacific, east to the Atlantic, north to Greenland, and return to California across central North America.
