Intro. to data assimilation: a toy example
¥ Assume we
have an object, a stone in space
¥ We want to
estimate its temperature T
(oK)
accurately
by measuring the radiance y
(W/m2)
that it emits. We have an observation model:
¥ We also have
a forecast model for the temperature
¥ We will
derive the data assim eqs (KF and Var) for this toy
system (easy to understand!)
¥ Will compare
the toy and the real
huge vector/matrix equations: they are the
same!
