3. Introduc4on
The
hydrological
and
meteorological
community
have
recently
converged
toward
a
new
integrated
simula5on
paradigm.
Holis5c
and
physically-‐based
view
of
the
energy,
water,
and
ma=er
cycle
across
a
range
of
spa5al
and
temporal
scales.
New
opportuni5es
and
grand
challenges:
Integrated
diagnosis
of
the
catchment-‐scale
energy
and
water
cycle
using
fully-‐coupled
simula5ons
and
observa5ons.
Mo#va#ons
of
the
work:
• Powerful
tools
to
test
scien5fic
hypothesis.
• Integrated
assessment
of
the
water
cycle
for
long-‐term
climate
projec5ons
and
short-‐
and
medium-‐term
weather
forecasts.
• Improved
monitoring
networks
(e.g.,
mul5ple
co-‐located
measurements)
that
cover
the
SVA
con5nuum.
