Satellite observation is one of the most impactful sources of observations assimilated into weather prediction models. Satellite data provide spatially and temporally uniform information of the atmosphere and are especially valuable over locations with limited traditional observations. However, the use of satellite observations is limited by their relatively lower vertical resolution, difficulties in handling clouds and precipitations, and uncertainties in Earth surface contribution to radiation.

This talk will briefly go over our past research on scattering properties of ice hydrometers in millimeter wavelength range, and their applications in assimilating microwave satellite observations. Then I will focus on two methods we recently developed 1) to reduce uncertainties from errors in surface properties by combining multiple satellite channels, and 2) dimension reduction for hyperspectral observations.
