Introduction
This page describes how to access the offline version of the new ECMWF radiation scheme "ECRAD". ECRAD is used in ECMWF Integrated Forecasting System from Cycle 43R3. It is 30-35% faster than the McRad scheme used in earlier cycles, and its modular design allows the spectral resolution, the description of cloud and aerosol optical properties, and the solver, to be changed independently of one another.
Documentation
- The new scheme is described in the ECMWF Technical Memorandum by Hogan and Bozzo (2016).
- Three solvers are available: McICA (Pincus et al. 2003), Tripleclouds (Hogan and Shonk 2008) and SPARTACUS (Hogan et al. 2016).
- Gas optical properties are provided by the RRTM-G model from Atmospheric and Environmental Research (AER).
- Radiation is documented in Part IV, Chapter 2 of the IFS Documentation.
