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

April 19, 2022

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.

Congratulations to ESSIC/AOSC Professor Zhanqing Li doctoral-advised student Tianning Su, who has recently earned the Charles A. Caramello Distinguished Dissertation Award!

V05 (top) and V07 (bottom) F16 SSMIS gridded brightness temperature (TB) difference between ascending and descending orbits. The presence of highlighted coastlines in V05 indicates errors in the V05 geolocation due to incorrect instrument pointing parameters. The pointing parameters are updated for V07 and the absence of highlighted coastlines indicates the V07 pointing parameters are more accurate than V05.

Special Sensor Microwave Imager/Sounder Updates for the Global Precipitation Measurement V07 Data Suite

March 30, 2022

A new article in IEEE Transactions on Geoscience and Remote Sensing details the new updates to the special sensor microwave imager/sounder for the Global Precipitation Measurement (GPM) Version 7 Data Suite. Rachael Kroodsma, ESSIC/CISESS Assistant Research Scientist, was first author on the paper.

Giant Lenticular Cloud, Seen from the Ground & in Space!

March 11, 2022

A giant lenticular cloud was seen in Maryland at about 5:50 pm on March 1st, 2022. ESSIC/CISESS Post-doctoral Associate Daile Zhang captured the cloud in Figure 1 below and a video posted to her Twitter account. GOES-East also detected the cloud as seen in Figure 2 and 3.
