Re: Use of RTOFS for Current.Gribs - Gulf of Maine

Did-g thanks for finding that new website!



It's providing Nowcast and short term forecast (48hr) and the screens are very good, and it is much more straight forward with the interface! Huge difference from what I was trying to do before.

OFS Operational Forecast System - Five different areas, one of which is Gulf of Maine
For Currents use Forecast 48 hours
For Wind use Forecast 48 hours

It would be very helpful if we could download the grib file with both wind and currents using our grib_pi.

It seems someone at NOAA did the conversion

If you can find where they store grib output you're set.

Great, hope you'll get an answer.


I did a quick and dirty conversion at:

http://grib-downloader.tk/POLAR/GOM.grb
but it downloaded 3 GBytes for producing a 20MBytes file and it's only 19H not 48H, moreover you need a yet to be released OpenCPN or Xygrib for displaying current in polar coordinates:

Not an installer, replace XyGrib.exe
