Overview of the Meso-NH model version 5.4 and its applications (2018, methodology): “The main differences from the original code concern the implementation of the SW version of RRTM with 14 bands and 112 g points (Morcrette et al., 2008) and some modifications regarding the treatment of unresolved cloud horizontal heterogeneities.”
The ERA5 global reanalysis (2020, methodology): “The radiation scheme used in ERA5, McRad, described by Morcrette et al. (2008), is a major upgrade from the scheme used by ERA-Interim.”
ERA‐20CM: a twentieth‐century atmospheric model ensemble (2015, methodology): “The IFS radiation is based on the McRad scheme (Morcrette et al., 2008).”
Comparison between meteorological re-analyses from ERA-Interim and MERRA and measurements of daily solar irradiation at surface (2015, methodology): “It can be noted that the radiative scheme used at ECMWF for forecasts has changed from that used in ERA-Interim for a better one in June 2007 (cycle 32R2 at the ECMWF Integrated Forecasting System) [21,23].”
Advances in simulating atmospheric variability with the ECMWF model: From synoptic to decadal time‐scales (2008, methodology): “…to give an overview of the performance of Cy32r3 compared to previous model cycles, in particular Cy32r2 that had received a substantial upgrade to the radiation scheme with a new shortwave code and the introduction of McICA (Monte Carlo Independent Column Approximation) (Morcrette et al., 2008).”
Radiative forcing by long‐lived greenhouse gases: Calculations with the AER radiative transfer models (2008, methodology): “This includes the operational use of RRTMG_LW or SW in the ECMWF weather forecast system [ Morcrette et al., 2008 ], the NCEP global forecast system (GFS) model, the Weather Research and Forecasting (WRF) model, and the ECHAM5 climate model [Wild and Roeckner, 2006] among other applications.”
SEAS5: the new ECMWF seasonal forecast system (2018, methodology): “Cloud–radiation interactions are taken into account using the McICA (Monte Carlo Independent Column Approximation) method (Morcrette et al., 2008).”
Introduction to the SPARC Reanalysis Intercomparison Project (S-RIP) and overview of the reanalysis systems (2016, methodology): “ERA-20C replaces the Fouquart and Bonnel (1980) shortwave scheme with a modified version of the RRTM (Morcrette et al., 2008) and is the first ECMWF reanalysis to use the Monte Carlo Independent Column Approximation (McICA) for representing the radiative effects of clouds.”
A Flexible and Efficient Radiation Scheme for the ECMWF Model (2018, background): “The Morcrette (1991)schemewasusedinthe1990s,andthedevelopmentsmadeinthatdecadewereoutlinedbyMorcrette, Barker, et al. (2008).”
