N2 - This paper presents a novel global all-weather sea surface temperature (SST) retrieval algorithm designed to address the challenge of accurately measuring SST in the presence of precipitation. Conventional microwave radiometer SST retrievals are highly susceptible to rain contamination, resulting in significant data gaps and reduced accuracy in critical regions. The global all-weather SST (GAWSST) algorithm mitigates this issue by leveraging linear combinations of vertically and horizontally polarized brightness temperatures at 6,10, and 18 GHz acquired by the Advanced Microwave Scanning Radiometer-2 (AMSR2). Comparative analysis with traditional methods and model outputs validates the algorithm's effectiveness, highlighting its robustness in rain-affected regions, particularly in tropical convection environments such as tropical cyclones.
