New Sea Surface Temperature (SST) ESDR Released

1. New Sea Surface Temperature (SST) ESDR Released Daily global SST map at highest resolution possible (1 km) “MUR SST” receives heavy usage in first 3 months of release Who/What/Where/When/Why • Project and PI: Multi-Scale Ultra-high Resolution (MUR) SST Project, T. Mike Chin, JPL. • Produces a daily SST gridded analysis at 1-km resolution by merging AMSR-E microwave and MODIS/AVHRR infra-red retrieval data. • Implemented a wavelet-based analysis algorithm (MRVA) for the data fusion task involving heterogeneous scales. • Extended MRVA implementation to cover the globe.

Relevance to NASA Impact • Contributes to improved understanding of ocean physics which will aid in improving climate models. • Aids accurate representation of air-sea coupling in atmosphere-ocean coupled models. • Increases our understanding of the role of oceans and atmosphere in the climate system and improves our predictive capability. • MUR combines the wide-swath high-resolution features of MODIS data with cloud-resistant (microwave) capability of AMSR-E data. • MUR product usage at PO.DAAC ranked #5 by volume and #9 by users for June 2011, the third month of release. Science Application • Studies of meso- and submeso-scale phenomena and physics of ocean surface, air-sea interaction, weather. • Oceanic fronts, SST gradients, and marine biology.
