SST ANALYSES GOAL: To generate real-time daily global high-resolution SST analyses, with emphasis on resolving meso-scale ocean features and patterns. Including the location of ice. (ie: Gulf Stream, eddies; coastal waters, bays and in-land lakes)
OPERATIONS: • Daily Real-time global SST (RTG_SST_HR) analysis • (1/12o latitude, longitude resolution) is generated every 24-h (22:30 UTC) using latest 24 h of real-time data. (implemented – September 27, 2005) • Daily Real-time global SST (RTG_SST) analysis • (1/2º latitude, longitude resolution) is generated every 24-h (22:30 UTC) using latest 24 h of real-time data. (implemented – January 30, 2001). Running in parallel. • .Validations statistics are computed immediately following completion of the operational runs for both systems and are available on the MMAB SST WEB page.
Comparisons of the (blended) global daily SST analysis systems
Test and Experimental SSTAnalysesusing various Satellite Platforms • 1) GOES 11 & 12 SST Data Analyses • Passive IR - restricted by clouds • NOT global; coverage60s -60N & 180W – 30 W • BUT, dense resolution retrievals (1/20 D lat,lon) hourly, • averaged daily • 2) AMSR SST Data Analyses • Passive MW – almost all weather capability, except for rain • But, low spatial resolution retrievals (37km) • 3) AVHRR (NOAA 17 & 18) plus AMSR Data Analyses • NOTE; METOPS-A replaces NOAA 17
