Validation Test Report for NFLUX PRE: Validation of Specific Humidity, Surface Air Temperature, and Wind Speed Precision and Accuracy for Assimilation into Global and Regional Models
Abstract
The Naval Research Laboratory (NRL) Ocean Surface Flux System (NFLUX) provides near-real-time surface products of wind speed at 10 meters, specific humidity at 5 meters, and air temperature at 5 meters height. These products use simple multiple linear regression algorithms for the Special Sensor Microwave Imager/Sounder (SSMIS) and the Advanced Microwave Sounding Unit (AMSU) passive microwave sensors flying onboard polar-orbiting satellites combined with model-based sea surface temperature fields. Optimal coefficients for the multiple linear regression algorithms were developed using a simple bootstrapping technique. Adjustment factors were also developed to improve the performance of the algorithms for observations in the higher ranges of the products. Global and zonal bands statistics are presented for each of the products. The continued planning for passive microwave sensors for future satellite missions will allow the algorithms and the techniques to continue to be evolved and exploited for many years.
