NRL fully integrates GPS radio occultation into global weather prediction

After rigorous validation for its positive impact on improving forecast accuracy, scientists at the NRL Marine Meteorology Division have transitioned the assimilation of GPS Radio Occultation (RO) data into the operational U.S. Navy Global Prediction System (NOGAPS). The assimilation of GPS RO reduces the NOGAPS upper-tropospheric and lower stratospheric temperature biases, introducing a complementary interaction with the radiance observations from other sensors being assimilated into the system.
