Reconstructions of the radiation fluxes at the top of the atmosphere and net surface energy flux over 1985-2017 - DEEP-C Version 4.0

Abstract

In order to study the energy flow in the climate system, the radiative fluxes (OLR, ASR and NET) at the top of atmosphere (TOA) prior to the CERES period have been reconstructed using satellite observations of CERES v4.1 and ERBS WFOF v3.0, atmospheric reanalysis (ERA5) and AMIP6 model simulations. The new approach using the mass-corrected atmospheric energy divergencies (transports) and consistent enthalpy treatment of water substances is employed to estimate the net surface energy fluxes. This is the version 4.0 of DEEP-C dataset created in September 2020. CERES version 4.1 and ERBS WFOV version 3.0 are used. The TOA flux anomaly is constrained by WFOV anomaly in each 10 degree x 10 degree grid box. The atmospheric energy transport is based on the new enthalpy treatment of water substances (Mayer et al. 2017).
