ERBE_S4G_WFOV_NF_N10_1 is the Earth Radiation Budget Experiment (ERBE) S-4G Nonscanner,Wide Field of View (WFOV) Numerical Filter (NF) 5 degree nested to 10 degree Regional Averages data set. It is in HDF format. Data collection for this data set is complete. ERBE was a multi-satellite system designed to measure the Earth's radiation budget. The ERBE instruments flew on a mid-inclination National Aeronautics and Space Administration (NASA) Earth Radiation Budget Satellite (ERBS) and two sun-synchronous National Oceanic and Atmospheric Administration (NOAA) satellites, NOAA-9 and NOAA-10. NOAA-9 and NOAA-10 provided global coverage and the ERBS provided coverage between 67.5 degrees north and south latitude. Each satellite carried both a scanner and a non-scanner instrument package. The scanner instrument package contained three detectors to measure shortwave (0.2 to 5 microns), longwave (5 to 50 microns) and total waveband radiation (.2 to 50 microns). Each detector normally scanned the Earth perpendicular to the satellite ground-track from horizon-to-horizon. The detectors were thermistors which used space views on every scan as a reference point to guard against drift. They were located at the focal point of a f/1.84 Cassegrain telescope, whose aluminum-coated mirrors were overcoated to enhance ultraviolet reflectivity. The total channel had no filter; therefore it absorbed all wavelengths. The shortwave channel was a fused silica filter which transmitted only shortwave radiation. The longwave channel was a multilayer filter on a diamond substrate to reject shortwave energy and accept longwave. To enhance the spectral flatness of the detectors, each thermistor chip was coated with a thin layer of black paint. The effective field of view of the scanner was 3 degrees. The ERBE S-4G product contained averages of radiant flux and albedo on regional, zonal, and global scales. The data for the S-4G product were arranged by parameter values. The various combinations of the satellites reflected the actual duration of the scanners.

ERBE_S10_WFOV_NF_NAT_1 is the Earth Radiation Budget Experiment (ERBE) S-10 Wide Field of View (WFOV) Numerical Filter (NF) Earth Flux and Albedo data product. Data collection for this product is complete. It is available in the Native (NAT) Format. ERBE was a multi-satellite system designed to measure the Earth's radiation budget. The ERBE instruments flew on a mid-inclination National Aeronautics and Space Administration (NASA) Earth Radiation Budget Satellite (ERBS) and two sun-synchronous National Oceanic and Atmospheric Administration (NOAA) satellites (NOAA-9 and NOAA-10). Each satellite carried both a scanner and a non-scanner instrument package. The non-scanner instrument package contained four Earth-viewing channels and a solar monitor. The Earth-viewing channels had two spatial resolutions: a horizon-to-horizon view of the Earth, and a field-of-view limited to about 1000 km in diameter. The former was called WFOV and the latter the medium field-of-view (MFOV) channels. The solar monitor was a direct descendant of the Solar Maximum Mission's Active Cavity Radiometer Irradiance Monitor detector. Due to the concern for spectral flatness and high accuracy, all five of the channels were active cavity radiometers. The MFOV (medium-field-of-view) SF (shape factor) S-10 contained inverted daily, monthly hourly, and monthly averages of shortwave and long-wave radiant fluxes at the top-of-the-atmosphere for one month. This data set was produced for each of the satellites (ERBS and NOAA-9) and the combination of satellites, which were operational during the data month. The values for this data set were derived using the shape factor technique (Smith et al. 1986). As described in the Earth Radiant Fluxes and Albedo, Scanner S-9, Non-scanner S-10/S-10N User's Guide, the data contains a 30 byte header, 67 scale factors which were used to scale the data in the first record, and 26 scale factors which were used to scale the data in the second record. The data set also contained two records for each processed region. The first record was of fixed length (990 words) and contained averaged data. The second record was of variable length and contained individual hour box estimates. The length of the second record, in words, was calculated by multiplying the number of hour boxes (978th word of record one) by the number of values stored for each hour box (38 for the non-scanner).

ERBE_S4G_WFOV_SF_1 is the Earth Radiation Budget Experiment (ERBE) S-4G Non-scanner, Wide Field of View (WFOV) Shape Factor (SF) 10 degree Regional Averages in HDF data product. Data collection for this product is complete. The data set consists of non-scanner, wide field-of-view data, processed using the shape factor data reduction technique and averaged to a 10.0 degree grid scale. Monthly (day), monthly (hour), daily, and monthly hourly averages were determined for each region. The data are represented as 8-bit, 16-bit, and 32-bit integers. Earth Radiation Budget Experiment (ERBE) was a multi-satellite system designed to measure the Earth's radiation budget.

The former was called the wide field-of-view (WFOV) and the latter the medium field of view (MFOV) channels. For each of the two fields of view, there was a total spectral channel which is sensitive to all wavelengths and a shortwave channel which used a high purity, fused silica filter dome to transmit only the shortwave radiation from 0.2 to 5 microns. Because of the concern for spectral flatness and high accuracy, all five channels on the non-scanner package were active cavity radiometers. The ERBE S-4G product contained averages of radiant flux and albedo on regional, zonal, and global scales. The data for the S-4G product were arranged by parameter values. The ERBE S-4G WFOV product was available as a combination of all operational spacecraft. Products have been archived from November 1984 - January 1985 and June 1989 - February 1990 for ERBS; February 1985 - October 1986 for ERBS/NOAA-9; November 1986 - January 1987 for ERBS/NOAA-9/NOAA-10; and February 1987 - May 1989 for ERBS/NOAA-10. The various combinations of the satellites reflected the actual duration of the scanners.

ERBE_S7_NAT_1 is the Earth Radiation Budget Experiment (ERBE) S-7 Monthly Medium-Wide Data Tape (MWDT) data set, which is in Native (NAT) format. The MWDT (S-7) product contains a condensed version of the non-scanner data that were found on a monthly set of Processed Archival Tapes (PAT), except that the shortwave estimates of the radiant exitance at the top-of-atmosphere (TOA) were based on the mostly cloudy over ocean bidirectional model. The MWDT product then provided a consistent data set of non-scanner TOA estimates which were not dependent on the operational status of the ERBE scanner instrument. ERBE was a multi-satellite system designed to measure the Earth's radiation budget. ERBE instruments flew on a mid-inclination National Aeronautics and Space Administration (NASA) Earth Radiation Budget Satellite (ERBS) and two sun-synchronous National Oceanic and Atmospheric Administration (NOAA) satellites (NOAA-9 and NOAA-10). Each satellite carried both a scanner and a non-scanner instrument package. The S-8 contained all satellite and viewing geometry, and all scanner and non-scanner radiometric measurements in engineering units with flags defining their validity. It also contained quantities such as scanner measurements corrected to flat spectral responses, the scene identified for each scanner pixel, the estimate of radiant flux at the top-of-the-atmosphere (TOA) for each scanner pixel, and the estimates of the radiant fluxes from the non-scanner measurements. The data were for a 24-hour period and one satellite. If all three satellites were operational on the same day, three separate S-8s were required for a full set of ERBE data. The data period started at Greenwich midnight (zero Universal Time) and continued for 24 hours and the period was divided into 16-second intervals.

ERBE_S10N_WFOV_SF_ERBS_Regional is the Earth Radiation Budget Experiment (ERBE) through Earth Radiation Budget Satellite (ERBS) Wide-field-of-view Nonscanner Observations Edition 4.1 data product. Understanding the mean and variability of the Earth's radiation budget (ERB) at the Top-of-Atmosphere (TOA) and surface is a fundamental quantity governing climate variability and, for that reason, NASA has been making concerted efforts to observe the ERB since1984 through two projects: ERBE and Clouds and the Earth's Radiant Energy System (CERES), that span nearly 30 years to date. The ERBE MEaSUREs project uses knowledge gained in the last 10 years through CERES data analyses and applies the knowledge to existing data to develop long-term (nearly 30 years) consistent and calibrated data product (TOA irradiances at the same radiometric scale) from multiple missions (ERBS and CERES). This project proposes to produce level 3 surface irradiance products that are consistent with observed TOA irradiances in a framework of 1D radiative transfer theory. Based on these TOA and surface irradiance products, a data product will be developed which contains the contribution of atmospheric and cloud property variability to TOA and surface irradiance variability. All algorithms used in the process are based on existing CERES algorithms. All data sets produced by this project will be available from the Atmospheric Science Data Center.
