Use and impact of satellite data in the NZLAM mesoscale model for the New Zealand region

Abstract

We describe the current configuration of the New Zealand Limited Area Model (NZLAM) and associated data assimilation system, summarise current data use and present recent work on quantitative verification of NZLAM forecasts. We compare the accuracy of global model forecasts and NZLAM forecasts with initial conditions derived a) from interpolated global analyses and b) using variational data assimilation, and quantify the impact of the use of ATOVS data in the NZLAM variational data assimilation system. Future research directions are described briefly.
