OFS Salish Sea and Columbia River Currents
| Provider: | Center for Operational Oceanographic Products (NOAA) |
| Model scope: | North America West Coast |
| Update frequency: | every 24 hours |
| Resolution: | 0.3nm, 0.6km |
| Model duration: | 57 forecasts starting at 0 hr, ending at 3 days |
| Parameters: | current, tide |
| GRIB model date: | Sat Dec 21 03:00:00 2024 UTC |
| Download date: | Sat Dec 21 08:27:23 2024 UTC |
| Download delay: | 5hr 27min |
Note: the Download delay is the amount of time required for the GRIB model to compute its forecast and then for the LuckGrib cluster to download the data and make it available. The LuckGrib delay is generally less than 10 minutes, the remainder of the delay is the model compute time.
Description
The Operational Forecast System (OFS) series of models is run by the National Ocean Service (NOS) and the National Weather Service’s (NWS), both a part of the National Oceanic and Atmospheric Administration (NOAA).
https://tidesandcurrents.noaa.gov/images/ofs/sscofs_spatialmap.pngThe Salish Sea and Columbia River OFS model is calculated using a bathymetry following irregular grid which has almost 240,000 grid nodes. The results of this computation are then sampled, by OFS, into a regular latitude / longitude aligned grid. The data on this regular grid are then converted to GRIB format by LuckGrib.
Tide data
Note that the OFS models contain tide height data. This tide data may be superior to the official forecasts, as they take into account atmospheric conditions and river runoff.
Studying the tidal heights across this region using the visual tools in LuckGrib can be an excellent way to understand how tides progress the further away from an ocean inlet an area is.
