- | Starting with ATOVS in 1999, the use of sounder data has become widespread with many NWP centres reporting strong positive impact, especially when directly assimilating the radiances. | + | Starting with ATOVS in 1999, the use of sounder data has become widespread with many NWP centres reporting strong positive impact, especially when directly assimilating the radiances. |
Adjoint-based sensitivity studies have shown that the impact of satellite sounding data is far larger than for any other observation type within a variational analysis system. Observing system experiments (OSEs) also show that the impact of observations, | Adjoint-based sensitivity studies have shown that the impact of satellite sounding data is far larger than for any other observation type within a variational analysis system.
