meteorologists, hydrologists, biologists and ecologists can be brought together
with applications specialists concerned with the management of water, agricul-
tural and industrial resources and public health.
Important points in this chapter
Purpose of SVATS
: is to specify the lower boundary conditions in atmospheric
models, the upper boundary conditions in hydrological models, or provide
the interface between land surfaces and the atmosphere in coupled models.
●
Function of SVATS
: is to calculate the exchange of energy, water, and carbon
dioxide and perhaps also other trace gases between land surfaces and the
atmosphere, and sometimes also components of the surface water balance
from 'forcing data' that comprises frequently sampled (either modeled or
measured) values of near-surface weather variables.
