  abstract = {{A simple parameterization of the hydrologic exchanges between the
soil-vegetation system and the atmosphere (SECHIBA) has been developed
for use within atmospheric general circulation models (AGCM).For each
grid box of the model, eight land surface types (bare soil plus seven
vegetation classes) are defined, each of them covering a fractional area
of the grid box and allowed to be found simultaneously. Over each of
these covers the transfers are computed: evaporation from soil,
transpiration from plants through a resistance defined by the concepts
of stomatal resistance and architectural resistance, and interception
loss from the water reservoir over the canopy. These fluxes are then
averaged over the grid box to derive the total amount of water vapor
that is transferred to the first atmospheric level of the AGCM.
Parameterization of soil water allows for the moistening of an upper
layer, of variable depth, during a rainfall event.This new scheme is
quite simple and requires prescription of a restricted number of
parameters: seven for each class of vegetation and four for the soil.
Nevertheless, it is demonstrated that the latent heat fluxes it
simulates are quite comparable to the ones simulated by the
Biosphere-Atmosphere Transfer Scheme or calculated by Shuttleworth over
the tropical rainforest of the Reserva Ducke (Amazon), with no tuning
