JHT Project: Operational SFMR-NAWIPS Airborne Processing and Data Distribution Products

This project aims to develop auto calibration algorithms, real-time quality control tools, and improved retrieval processes for SFMR data to enhance the accuracy and efficiency of airborne measurements of ocean surface wind speed. The project also includes the development of bathometry and land flags to improve data interpretation.
