This core-mission data product contains 24 hours of instantaneous Level-1b CERES data for a single scanner instrument. It contains instantaneous radiance measurements recorded every 0.01-second for views of space, internal calibration, solar calibration and Earth and it is primarily used as input to the Level 2 CERES data products.
This core-mission data product provides a continuation of the ERBE record of S-8 radiative fluxes at the TOA, analyzed using the same algorithms that produced the ERBE data. The ES-8 product contains 24 hours of instantaneous unfiltered radiances and radiative fluxes for a single scanner instrument determined with a scene identification algorithm and Angular Distribution Models (ADMs) which are “like” those used for ERBE.
This core-mission data product provides a continuation of the ERBE record of S-9 radiative fluxes at the TOA, analyzed using the same algorithms that produced the ERBE data. The ES-9 product contains a month of space and time averaged CERES data on a 2.5-degree grid for a single scanner instrument as well as for combinations of scanner instruments.
This core-mission data product provides a continuation of the ERBE record of S-4 radiative fluxes at the TOA, analyzed using the same algorithms that produced the ERBE data. Daily average, hourly average over the month, and overall monthly average TOA radiative fluxes are given in 2.5-, nested 5- and nested 10° regions. Zonal and global monthly average fluxes and albedos are also included.
This core-mission data product contains one hour of instantaneous CERES data for a single scanner instrument. The SSF merges instantaneous CERES radiative fluxes with cloud and aerosol information from MODIS on Terra or Aqua and meteorological parameters from the GMAO GEOS-DAS V4.0.3 product. Radiative fluxes are inferred from measured radiances using new CERES Angular Disitrbution Models (ADMs) developed from two years of rotating azimuth plan scan CERES measurements.
The is an enhanced data product that is a fusion of measurements from CERES, MISR, and MODIS. The MISR Level 1B2 Ellipsoid and Terrain radiances are identified with CERES Terra measurements reported in the SSF product for days the CERES instruments (FM1 and FM2) are in along-track scanning mode. Each CERES footprint contains multiangle and multispectral MISR radiances at nine angles and cloud, aerosol and radiation parameters from the SSF.
CERES Monthly gridded TOA/Surface fluxes and clouds (SFC)
This archival data product is a core-mission data product that contains hourly single satellite flux and cloud parameters averaged over regions in a 1.0-degree nested grid, processed and written in local time. Input to the SFC subsystem is the SSF archival data product. Each SFC covers a single month swath from a single CERES instrument mounted on one satellite.
This core-mission product contains daily and monthly 1° regional, zonal and global averages of the clear and all-sky TOA LW and SW fluxes together with the associated MODIS-derived cloud and aerosol properties, and GMAO meteorological properties. Temporal averaging assumes constant meteorology between observation times to complete the diurnal cycle.
This core-mission data product contains one hour of instantaneous data for a single scanner instrument. For each CERES FOV on the SSF, the CRS provides Fu-Liou radiative transfer modeled vertical flux profiles evaluated at five levels in the atmosphere (the surface, 500 hPa, 200 hPa, 70 hPa, and TOA), and aerosol and cloud forcing data at the surface and TOA. The computations use MODIS cloud and aerosol properties as input and are constrained at the TOA by CERES fluxes.
This archival data product is a core-mission data product that contains hourly single satellite flux and cloud parameters averaged over 1° regions. Input to the FSW subsystem is the CRS archival data product. Each FSW covers a single month swath from a single CERES instrument mounted on one satellite.
CERES and GEO-Enhanced TOA/Within-Atmosphere/Surface Fluxes and Clouds (SYN1deg -3Hour, -Month; -M3hour)
This is a core mission product that contains surface, within-atmosphere Fu-Liou radiative transfer modeled fluxes and both computed and observed TOA fluxes together with the associated MODIS cloud, aerosol and GMAO meteorological input data. Also included are aerosol and cloud forcing data at the surface and TOA, and surface photosynthically active radiation and UV. Computed hourly, inputs are from a merged CERES/MODIS Terra, Aqua and GEO cloud and flux data-stream. Temporal averaging relies on geostationary observations to complete the diurnal cycle between Terra and Aqua observation times. These data are provided at 3-hourly, daily, monthly and monthly 3-hourly levels at the CERES 1° grid resolution as well as 1° zonal and global scales.
This product contains all-sky Top-of-Atmosphere fluxes that have been optimally adjusted within their uncertainty to be consistent with our best estimate of the global net flux based upon in-situ ocean heat content measurements. It also includes spatially interpolated clear-sky fluxes derived at the sub-CERES footprint scale from combined CERES/MODIS data. EBAF is intended for climate model evaluation, estimating the Earth’s global mean energy budget and to infer meridional heat transport. EBAF is derived from the SYN1deg-Month data product which uses the diurnally complete temporal averaging from GEO. These data are provided at the monthly level at the CERES 1° grid resolution as well as 1° zonal and global scales.
These data products were designed to emulate the NASA-GISS ISCCP-D2like formatted products, so that they meet the needs of the climate community and can easily be incorporated into GCMs with ISCCP simulators. They contain the MODIS and geostationary cloud properties retrieved by CERES stratified by pressure level, optical depth and cloud phase. The “-day” product provides the daytime MODIS cloud properties, the “-nit” product provides the corresponding nighttime clouds, and the “-geo” product provides daytime 3-hourly geostationary cloud retrievals. They also include MODIS derived ice and liquid particles sizes and IR emissivity. These data products are provided at the monthly 3-hourly level and monthly mean averages, at the CERES 1° grid resolution.
