"Current" is shown in the zyGrib Weather Data display area right below "Wind gust," but I don't find a word to return Current via email request from gribauto. Is Current a piece of information we can get? I would love to be able to see the Gulf Stream, for example, or better still, the Gulf Stream eddies.

We will be sailing from St. Thomas to Rhode Island in early May, downloading from gribauto via Iridium SAT phone email daily. We are very excited about all the data available. Kudos to you on a really fabulous program!!!!

I now see on the home page that Current is not available from zygrib. Does anyone know of a source for current that can be displayed by zygrib?

Thanks!

Hello Dorothy,

There is an excellent solution provided by Saildocs.
Send a mail to: query@saildocs.com with the following request:
send RTOFS:49N,16N,083W,052W|0.5,0.5|24,48..192|CUR
Please be sure that there is nothing else, like a signature or message from your antivirus software, in your mail.

The gribfile uses 24h timesteps which cannot be changed, but you can adjust the resolution (1.0,1.0) and the number of hours ahead to reduce file size. The information displays without any problem in zyGrib.

Hope this information is helpfull and wishing you a very good trip.

Regards,
Ruud

Ruud -- Thank you very much. I see that all kinds of info is available from saildocs, including other grib info and forecasts. I'm digging into it! Thanks for the lead and for the specific current retrieval command, which worked perfectly.

Fair winds,
