Definition

  • The Langley Research Center Distributed Active Archive Center (LARC DAAC), Hampton, Virginia, is one of several Earth science data centers comprising the Earth Science Data and Information System (ESDIS). The ESDIS program is a segment of the Earth Observing System (EOS), NASA's contribution to the Global Change Research Program. The LARC DAAC is responsible for archiving and distributing NASA science data in the areas of radiation budget, clouds, aerosols, and tropospheric chemistry. This DAAC will also archive some of the data sets which result from the EOS program and other elements of Mission to Planet Earth. Data Sets 1) ERBE - Earth Radiation Budget Experiment. Data are collected from three satellites (ERBS, NOAA-9, NOAA-10) carrying two ERBE instruments (scanner, nonscanner). The objective is to measure global albedo, fluxes, and solar incidence. The ERBE data comes in various data sets and formats. Some of the data are stored in HDF and are available via FTP. 2) ISCCP - International Satellite Cloud Climatology Project. ISCCP focuses on the study of the distribution and variation of cloud radiative properties. The objective is to improve the understanding and modeling of the effects of clouds on climate and also to elucidate the role of clouds in the radiation balance and improve our knowledge of the long-term global hydrologic cycle. The ISCCP data come in various data sets and formats. Some of the data are available on CD-ROM and via FTP. 3) SAGE - Stratospheric Aerosol and Gas Experiment. SAGE I gathered data concerning the spatial distribution of stratospheric aerosols, ozone, and nitrogen dioxide on a global scale. The goals of SAGE II are to determine the spatial distributions of stratospheric aerosols, ozone, nitrogen dioxide, water vapor, and cloud occurrence by mapping vertical profiles and calculating monthly averages of each. The SAGE data are available via FTP. 4) SRB - Surface Radiation Budget. The SRB data sets were calculated using data from ISCCP and ERBE. They are designed to give global daily and monthly averages of the albedo, irradiance, cloud properties, and meteorology. These data are available via FTP and CD-ROM. 5) FIRE - First ISCCP Regional Experiment. This series of experiments includes aircraft, satellite, and surface-based measurements of Cirrus and Marine Stratocumulus cloud parameters. The purpose of this program is to validate and improve ISCCP data products and cloud/radiation parameterizations used in general circulation models (GCMs). These data are available via FTP. 6) GTE - Global Tropospheric Experiment. Data are collected primarily from aircraft and ground-based instruments from a variety of areas such as the Amazon Rain Forest and the Northern tundra and boreal forest. Many parameters were measured including ozone, methane, PAN, CO, NO, nitrogen dioxide, carbon dioxide, and aerosols. The data are available via FTP and CD-ROM. 7) SAM II - Stratospheric Aerosol Measurement. This instrument was flown onboard the Nimbus-7 satellite and consisted of a one-spectral channel sun photometer, centered at 1.0 um, which viewed a small portion of the sun through the Earth's atmosphere during spacecraft sunrise and sunset. The data obtained from this instrument were used to determine the vertical distribution of stratospheric aerosols in the polar regions of both hemispheres. These data are available via FTP and CD-ROM.
