Abstract: n advance that made Gaussian-based three- and four-dimensional variational data assimilation (3D- and 4DVAR, respectively) operationally viable for numerical weather prediction was the introduction of the incremental ...

Abstract: he Moderate Resolution Imaging Spectroradiometer (MODIS) sensor aboard the Terra and Aqua satellites allows roughly for the same region of Earth to be sampled twice in a nowcasting time frame. Using the MODIS cloud mask ...

Abstract: n this paper four simple computationally inexpensive, direct insertion data assimilation schemes are presented, and evaluated, to assimilate Moderate Resolution Imaging Spectroradiometer (MODIS) snow cover, which is a ...
