NOAA NESDIS generates a new daily SST analysis combining Geostationary (GOES, MT-SAT and Meteosat) SST and POES and MetOp (AVHRR) data into a single high-resolution (0.10.1) product. This resolution was chosen to approximately match the Nyquist sampling criterion for the mid-latitude Rossby radius (~20 km) in order to ensure preservation of mesoscale oceanographic features such as eddies and frontal meanders. The methodology employs a rigorous multi-scale optimal interpolation which approximates the Kalman filter, together with a data-adaptive correlation length scale to ensure the balance between detail preservation and noise reduction. The new analysis has been a significant success, even when compared to other modern products which purport to be similar or higher resolution. Operational Microwave SST products (e.g. AMSR-E SSTs) will be incorporated into this analysis to obtain SSTs in areas of persistent cloud.
