The Kalman Filter Sensitivity method is used to compute the sensitive areas that are defined as follows.
Case A: Lead-time is 42h, optimization is 24h.
Case B: Lead-time is 54h, optimization is 18h.
Case C: Lead-time is 66h, optimization is (...)

The CONCORDIASI experiment is part of the International Polar Year (IPY 2007-2008).
Its primary objective is to study the assimilation of raw radiances collected by the
IASI instrument (onboard the polar satellite MetOp-1)
above the icy surface of Antarctica. To this end, (...)
