Abstract:

Design of a Low SWaP Dual-Band Radiometer for UAS Remote Sensing Applications Sea Surface Salinity (SSS) is crucial in oceanographic, coastal, atmospheric, and other applications. Knowing this variable well allows the scientific community to understand and monitor the behavior of both the ocean and the atmosphere. This way, the government and other stakeholders can make better decisions to protect life and property based on analysis and conclusions by NOAA scientists. During my NOAA Experiential Research and Training Opportunities (NERTO), our research focused on studying further which variables significantly impact the measurement of sea surface salinity from passive microwave radiometers. These variables are the Sea Surface Temperature, Earth Incidence Angle, Wind Speed, and Direction. We concentrated on the sensitivity of the retrieved SSS to each variable mentioned by calculating the brightness temperature (TB). The calculations are from the study of Meissner et al. and the theses of Wah and Mera. A function was designed on MATLAB and showed that brightness temperature is more sensitive to Sea Surface Temperature and Wind Speed. The highest error in SSS is 1.0183 PSU, meaning that this parameter impacts most the brightness temperature and the retrieved sea surface salinity. I will also discuss furthers steps of this research which will implement this function in the analysis of retrieving SSS for the new novel airborne sensor..
