JMA Begins Operational Use of MODIS Direct Broadcast Polar Winds: The Japan Meteorological Agency (JMA) began using Moderate Resolution Imaging Spectroradiometer (MODIS) direct broadcast (DB) polar winds in their operational weather forecast system on 2 February 2011. The DB winds are generated at three direct broadcast sites in the Arctic and one in the Antarctic. JMA reports that the DB winds provide significantly more wind information in the early model cycles than the operational MODIS wind product. New impact studies at JMA show that the operational and DB MODIS winds collectively have a positive impact on forecasts, particularly in the Southern Hemisphere, and also have a positive impact on typoon track forecasts beyond 48 hours.

Manuscripts on Boundary Layer Profiler Assimilation Accepted for Publication: Two manuscripts entitled “Assimilation of surface-based boundary layer profiler observations during a cool season observation system simulation experiment. Part 1: Analysis impact” and “Assimilation of surface-based boundary layer profiler observations during a cool season observation system simulation experiment. Part 2: Forecast assessment” were accepted for publication in Monthly Weather Review. The papers by Jason Otkin (Cooperative Institute for Meteorological Satellite Studies, CIMSS), D. Hartung (CIMSS), W. Feltz (CIMSS), R. Petersen (CIMSS) and D. Turner (National Severe Storms Laboratory) presented results from a regional-scale Observation System Simulation Experiment that examined how the assimilation of temperature, moisture, and wind profile observations from a network of surface-based profiling systems impacts the accuracy of atmospheric analyses and short-term model forecasts when using an Ensemble Kalman Filter data assimilation system (J.
