Description

Many agencies are interested in estimating the value and impact of surface weather observations collected by their networks of stations. Which stations provide significant benefit and which ones may provide largely redundant information compared to surrounding stations? A two-dimensional variational analysis system is used sequentially over limited domains (-200 km x -200 km) of the United States to examine the sensitivity of mesoscale surface analyses to the types of mesonet observations assimilated. Analysis errors assessed by data denial experiments for a variety of synoptic situations are determined for analyses that rely on RAWS and NWS/FAA observations.
