ERBE team released ERBS WFOV Nonscanner Observations Edition 4.0 data product

Release of Level 3 Edition4 TOA Radiation Budget dataset from ERBS WFOV Nonscanner Observations

The ERBE team announces the release of Level 3 Edition4 top-of-atmosphere (TOA) irradiance data products from Earth Radiation Budget Satellite (ERBS) wide-field-of-view (WFOV) nonscanner observations. The Edition4 dataset is available from January 1985 to December 1998. This task is made possible by the NASA Making Earth Science Data Records for Use in Research Environments (MEaSUREs) program. NASA has been making concerted efforts to observe the Earth radiation budget (ERB) since 1984 through two projects: Earth Radiation Budget Experiment (ERBE) and Clouds and the Earth’s Radiant Energy System (CERES). However, the past ERB dataset from ERBS has shown higher uncertainties in the later period and is not at the same radiometric scale as CERES. The recently released new Edition4 dataset uses improved algorithms to reprocess ERBS WFOV nonscanner observations based on lesson learned from CERES. In addition, these datasets are calibrated with CERES-derived irradiances and the spatial coverage is extended to global from 60N to 60S latitudes. The release of Edition4 ERBS datasets combined with that provided by CERES generates a long-term consistent TOA radiation budget, that spans nearly 30 years to date.

The dataset is distributed by NASA Langley Atmospheric Science Data Center (ASDC) and is available at https://eosweb.larc.nasa.gov/project/measures/long-term-toa-m
