Actually disregard, I just tested it on a few locations within very light precip areas and it looks like the threshold is now around 0.2mm or so. Thanks for getting back to me.
I think someone else may have mentioned this awhile ago as well but it'd be great if the ECMWF rainfall maps showed precip as low as say 0.2 or 0.1mm so areas of light precipitation don't get missed.
The lowest value currently shown on the scale for ECMWF 3hr precip is 1.5mm while for the rain accumulation, it's 5mm (although I'm not totally sure if lower amounts still show up on the maps?)
Adding precipitation types such as rain vs snow vs freezing rain (perhaps using colour-coding) to work out where snow would be more likely than rain would be great!
Just a suggestion: the current minimum threshold of 1.5mm for 3-hourly rain/snow map (and 5mm for the accumulation maps and 8cm for snow accumulation) means light precipitation such as areas of light showers often don't show up on Windyty forecasts.
If the threshold was lowered to say 0.2 or 0.1mm which are common standard thresholds for measuring observed precipitation, it would fix this issue.
When using the rain accumulation maps, I've sometimes noticed big square-shaped blank areas of missing data (example screenshot attached with affected area circled).
I've confirmed this problem by comparing with another source of ECMWF data.
Awesome work in getting so many ECMWF parameters onto Windyty by the way. Keep up the great work.
