Validation of NASA Sea Surface Temperature Satellite Products Using Saildrone Data

Sea Surface Temperature (SST) is at the core of many processes in oceans. Various remote sensing platforms have been used to obtain SST products different scales, but their validation remains a topic ongoing research. One promising platform an uncrewed surface vehicle called Saildrone. We use data from eight Saildrone deployments USA West Coast 2019 campaign validate MODIS level-2 and Multi-scale Ultra-high Resolution (MUR) level-4 satellite 1 km spatial resolution assess robustness quality levels over California Coast. Pixel-based comparisons between were performed, as well thermal gradient computed both pixel-base level using kriging interpolation. The results generally showed better accuracies for MUR products. characterization proved be valid areas covered by bad-quality pixels less lower-quality pixels. latter implies possible errors interpolation processes. demonstrated ability Saildrones accurately near-shore provide important information assessment
