This video demonstrates how to update a GRIB forecast.
Once you have requested the GRIB data for a region you are interested in, you can update the forecast when new data is available.
LuckGrib keeps track of your GRIB request objects. To update a forecast, simply click on the request object you want and submit it for download. You can modify the request by changing its region or altering the data requested if you wish.
If you ask LuckGrib to download the data associated with a request, and there is no new data available yet, the application will warn you that the data has not changed yet. This saves your downloading the same data twice.
