abstract = "South America has a large diversity of vegetation cover which
imposes substantial control on the hydrological and diurnal cycles
of several meteorological quantities. This paper presents the
integration and validation of the regional Eta Model coupled with
the Simplified Simple Biosphere Model (SSiB). The regional
atmospheric model was configured with 80-km resolution in the
horizontal and 38 layers. One-month continuous integrations were
performed for November 1997 (El Nino year) and November 1998 (La
Nina year). NCEP analyses were used as initial and lateral
boundary conditions, the latter updated every 6 hours. Observed
sea surface temperature, climatological soil moisture and surface
albedo were used as lower boundary conditions. The present work
focuses on the diurnal cycle of surface temperature, radiative
fluxes, sensible and latent heat fluxes, and relative humidity.
Four sites with different surface covers are chosen for the
evaluation. The vegetation types are: (i) tropical forest; (ii)
savannah; (iii) cultivation; and (iv) bare soil. A comparison of
model simulated diurnal cycle amplitude with observations and NCEP
analyses is shown.",
