Figure1: Differences in SCAN observations‐based ubRMSE during 1 April 2015-30 August 2021 time period: (a) SMOPScdr minus SMAP, (b) SMOPScdr minus SMOS, (c) SMOPScdr minus AMSR-2, (d) SMOPScdr minus ASCATA. Patterns for ASCATA and ASCATB are very similar. Sites in blue color highlight better performance.

A New NOAA Blended Soil Moisture Product that Does Not Rely on Model Climatology

May 3, 2022

ESSIC/CISESS Scientists Jifu Yin, Jicheng Liu and Ralph Ferraro published a new article last month that discussed their work with NOAA’s Soil Moisture Operational Product System (SMOPS). SMOPS is developed by National Oceanic and Atmospheric Administration (NOAA) to provide the real time blended soil moisture (SM) for Numeric Weather Prediction and National Water Model applications.

Microwave Snowfall Rate Product Captures Late Season Pacific Northwest Snowfall

April 19, 2022

The STAR scientist team of Huan Meng, Yongzhen Fan, Jun Dong, and Yalei You examined the performance of snowfall estimates from the passive microwave snowfall rate (SFR) product for the late season snowstorm that hit Washington and Oregon on April 13. The storm set the local record for most snow accumulation this late in the season, causing power outages and road closures across Portland, Oregon.

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.
