RE: Augment predictions with realtime data
Thanks for the information @idefix37 , the model time information is very helpful as well as the reported wind feature. Didn't know about either of these.
Yes I agree the 20m height for LDLC3 lighthouse can account for some higher wind than Windy. However, looking back over that day I still don't think it accounts for all the differences I saw (not that I expect predictions to be exact). Would the extra 10m account for a doubling of the wind speed? I suppose it can, you might know better than me.
While Windy may not use realtime information today to update the models, someone is going to do this. It would be great to start some experimentation on this. It would give you huge advantage if it panned out. But it would definitely be an investment to hire some people with that expertise.
Augment predictions with realtime data
Can predictions be updated with realtime information? Or at least let us know when the prediction was made. For example, right now 6/7/2020, I am looking at Windy data for a marine location near New London, CT. There happens to be an NOAA weather station here with wind data as well, so I can compare the Windy data to what is happening right now. So Windy says right now at 9:46AM EDT near the New London Ledge Light weather station that the wind speed is between 5Knts and 13 knts depending on the prediction model used. However the New London Ledge Light station shows the wind speed at 18knts at 9:25am (last reported) with gusts at 22knts.
Moreover if you look at the general prediction for this area today in Windy, it looks like very light air. The 1-hour increment trend for the day shows no model above 10knts at any time of day (ignoring gusts for now), which is weird cause if I just click the general area I did get that 13knt data.
So 10knts and under is pretty different than the 18knts and above we are seeing from NOAA data. Graph of data (this will show current data not when this post was made) https://www.ndbc.noaa.gov/show_plot.php?station=ldlc3&meas=wdpr&uom=E&time_diff=-4&time_label=EDT
How can windy adjust its models based on more realtime information?
