NFLUX PRE: Validation of New Specific Humidity, Surface Air Temperature, and Wind Speed Algorithms for Ascending/Descending Directions and Clear or Cloudy Conditions.

摘要

The Naval Research Laboratory (NRL) Ocean Surface Flux System (NFLUX) has been updated to include additional satellite sensors and improved satellite retrieval algorithms. In addition to data from the Special Sensor Microwave Imager/Sounder (SSMIS) and the Advanced Microwave Sounding Unit (AMSU) sensors, NFLUX also processes data from the Advanced Technology Microwave Sounder (ATMS) and Advanced Microwave Scanning Radiometer-2 (AMSR2) sensors. The original multiple linear regression algorithms have been updated to multiple polynomial regression algorithms based on a hyperbolic function, which also eliminates the need for additional adjustments for observations in the higher ranges of the products. For each satellite and ocean surface product combination four separate algorithms were developed based on ascending/descending orbits as well as clear/cloudy conditions. Global statistics are presented for each of the algorithm types for each sensor.
