GINA-WRF short-term forecast

GINA conducts study on data assimilation into the regional WRF model. The goal is to evaluate improvements made from bringing in the near realtime polar orbiting datasets into the weather model.

An experimental regional WRF model is running in GINA. It runs 4 times every day for analysis times of 00, 06,12, and 18Z.  The CrIS/ATMS sounding profile data (EDR) are assimilated to improve initial condition of every WRF run.  The level1 CrIS/ATMS data (SDR) are received by GINA/NOAA satellite facility at Gilmore Creek, they are then processed into level2 CrIS/ATMS sounding profile (EDR) data with the NUCAPS algorithm.

24-hour forecasts are produced for each analysis time.  The WRF outputs are shown at
