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

There is a more recent version of this item available.

Description

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).

Additional details Additional details Project Name: Diagnosing Earth's Energy Pathways in the Climate system (DEEP-C) Funders: Natural Environment Research Council (NE/K005480/1) Resource Language: English Collection period: From 1 January 1985 To 30 November 2017 Temporal coverage: From 1 January 1985 To 30 November 2017 Geographic coverage: global Data collection method: See publication references. Data processing and preparation activities: All files are in netcdf format. The downward net fluxes are defined as positive. The TOA radiation fluxes are from January 1985 to June 2019. The surface energy flux is the net energy flux from January 1985 to November 2017. Geodetic weighting can be found at https://ceres.larc.nasa.gov/science_information.php?page=GeodeticWeights. DEEPC_Fmass_v04_198501-201711.nc : as in version 3.0, the excess/deficit land surface fluxes are redistributed to the oceans zonally (using normal distribution weight in latitude direction).
