Description

Building on the ARM constrained variational analysis for single-column and for three dimension fields, we have been working on developing a high-resolution data assimilation system at kilometer scales to support research on cloud resolving modeling and LES for the ARM megasite. This presentation describes the status, unique issues, and preliminary results of such a data assimilation system. Current and potential input data for the assimilation system will be discussed. We will also show comparison of the analyzed winds and vertical velocity from the system with available retrieved wind fields.
