Huang, Shortwave TOA cloud radiative forcing derived from a long-term (1980-present) record of satellite UV reflectivity and CERES measurements , Journal of Climate 09/2015; DOI:10.1175/JCLI-D-14-00551.1 · 4.44, 2015.https://doi.org/10.1175/JCLI-D-14-00551.1http://hdl.handle.net/11603/26822A 34-yr record of shortwave top-of-atmosphere (TOA) radiative cloud forcing is derived from UV Lambertian equivalent reflectivity (LER) data constructed using measured upwelling radiances from the Nimbus-7 Solar Backscatter Ultraviolet (SBUV) and from seven NOAA SBUV/2 instruments on polar-orbiting satellites. The approach is to scale the dimensionless UV LER data to match the CERES shortwave cloud radiative forcing when they are concurrent (2000–13). The underlying trends of this new longer-term CERES-like data record are solely based on the UV LER record. The good agreement between trends and anomalies of the CERES-like and CERES shortwave cloud forcing records during the overlapping data period supports using this new dataset for extended climate studies. The estimated linear trend for the shortwave TOA radiative forcing due to clouds from 608S to 608N is 11.47W m⁻² with a 0.11 uncertainty at the 95% confidence level over the 34-yr period 1980–2013.16 pagesen-US© Copyright 01 Dec, 2015 American Meteorological Society (AMS).
