Effective on January 12, 2023, beginning with the 1200 Universal Coordinated Time (UTC) cycle, the National Centers for Environmental Prediction (NCEP) Central Operations (NCO) upgraded the Surge and Tide Operational Forecast System (STOFS, formerly ESTOFS) to Version 1.1.1. Please see the Service Change Notice (SCN) here for more details.
The Coast Survey Development Laboratory (CSDL) in NOAA/NOS/Office of Coast Survey, the developer of STOFS, would like to alert users to some items regarding this upgrade. Please see a Public Information Statement (PNS) that was recently published here for a description of these items, which include a change in URL for web graphic display of model output, changes in URL and names of the AWS S3 bucket for the STOFS-2D-Global component, a new AWS S3 bucket for the new STOFS-3D-Atlantic component, and description of known issues in the current version of STOFS-3D-Atlantic (e.g. erroneous ‘ponding’ in some watershed areas).
Finally, our collaborators at the Virginia Institute of Marine Science (VIMS) have helped put together a few slides (attached) for STOFS-3D-Atlantic explaining in more detail the erroneous ‘ponding’, fixes for the ‘ponding’ issue in the next model upgrade, and definitions of ‘water surface elevation/water level’ and ‘water level disturbance’, which is a new variable provided by STOFS-3D-Atlantic.
Thank you very much for your attention to this matter, and please feel free to forward this message to anyone who you think may be interested in the upgrade of STOFS to v1.1.1.
