Jeff Waldstreicher at the NWS Eastern Region Headquarters observed an apparent plume of relatively warm surface water, noted in 1 km, single swath MODIS SST imagery provided by CIMMS at the University of Wisconsin. SPoRT uses similar, 1 km imagery to develop a high resolution SST composite that combines several MODIS SST swaths into a single image, based upon numerous cloud-free observations. In the image below, the dominant, dark blue shades indicate water temperatures in the low to mid 40s, while water near the New Jersey coastline approaches 50 F. This plume of relatively warm water (4-6 F warmer than the adjacent, open water) is moving southward, likely driven by synoptic-scale, north winds. The discharge of water is the result of major flooding in upstream river basins, following the storm over the past week. This type of imagery demonstrates the high resolution detail provided by NASA’s polar orbiting instruments and future capabilities aboard NPP/NPOESS and the eventual launch of GOES-R.
