abstract = "This work evaluates the performance of two radiation
parameterization schemes in 30-day clear-sky runs of the Eta model
over a region in Southeast Brazil. Two versions of the Eta model
are compared: a version using the radiation scheme developed by
the Geophysical Fluid Dynamics Laboratory (GFDL) and a recently
developed version using the Rapid Radiative Transfer Model for GCM
(RRTMG). These simulations are compared against CMSAF satellite
data and surface station data. The simulation using RRTMG produced
downward surface shortwave radiation fluxes closer to observations
and reduced the systematic positive bias of the Eta simulation
using the GFDL scheme. The 2-m temperature negative bias found in
the Eta-GFDL simulations is reduced in the Eta-RRTMG simulations,
which results from a larger net total radiation in the Eta-RRTMG
simulations. The new version has better accuracy than the Eta
using the GFDL scheme for most of the evaluated variables,
particularly for clear-sky conditions.",
