  3. Project goal • Improve model performance by assimilating remotely sensed (AMSR-E) soil moisture into the Bureau’s numerical weather prediction models. • Develop a soil moisture product from AMSR-E observations • Assimilate this into LAPS, and investigate the impact on forecast skill 3

  4. Verification of AMSR-E derived soil moisture products in an Australian context • Near surface soil moisture • Spatial scale similar to AMSR-E (~50 x 50 km) • Sampling frequency close to daily • Understanding of finer spatial variation, diurnal cycle, and soil moisture profile dynamics 4

  5. Verification of 1-D LAPS simulation for NAFE region, with and without AMSR data: • Latent and sensible heat flux, atmospheric temperature, rainfall, soil moisture • Spatial scale similar to AMSR-E (~50 x 50 km) • High sampling frequency (hourly) 5
