NOAA/NCEI Blended Sea Surface Winds Product for Resolving Hurricane Winds

ESSIC/CISESS Scientist Korak Saha and collaborator Huai-min Zhang have been improving the NOAA/NCEI Blended Seawinds (NBS) product. NBS blends several satellite estimates of surface wind, providing more accurate and gap-free observational data for model calibration and quality control. NOAA has been producing a global gridded 0.25-degree and 6-hourly sea surface winds product that has wide applications in marine transportation, marine ecosystem and fisheries, offshore winds, weather and ocean forecasts, among others.

Rudlosky Captures Hurricane Laura Using AMSR2

The Advanced Microwave Scanning Radiometer 2 (AMSR2) onboard the GCOM-W1 satellite captured Hurricane Laura, the deadly Category 4 hurricane that hit Louisiana in late August. AMSR2 is a remote sensing instrument used to measure weak microwave emission from Earth’s surface and atmosphere. SCSB- and CISESS-led products captured Hurricane Laura at various stages of development. Visiting Assistant Research Scientist Scott Rudlosky shared several images to his Twitter feed, which show considerable lightning around the eye wall during Laura’s intensification.
