ECMWF provides forecast simulated radar base reflectivity (dBZ)
Why not provide this output on windy? It has an advantage over the 3 hr rainfall in that it shows instantaneous rainfall whereas the 3hr rainfall rate is an average over the last 3 hours.
It is easier to locate areas of convective activity with the simulated radar forecast as it does not average out rainfall over the previous 3 hours.
Please consider adding the ECMWF forecast simulated radar reflectivity to Windy
A example of an advantage:
ECMWF may forecast a line of convection moving steadily with the wind, for example. The forecast radar output will show this as a line whereas the 3hr rainfall rate currently on Windy will depict this line as a circle of colour as the rainfall is an average over the previous 3 hours.
In other words, the forecast radar output will provide additional detail to forecast precipitation.
@rogerdoger Hi, rain layer in Windy is 3h accumulation, not average. I did not find simulated radar in ECMWF products. Could you please send me some link?
a) ECMWF provides Simulated Satellite Data (SSD).
SSD are forecast images of cloud cover like those taken from satellites.
b) In this site
I found a product named "Base reflectivity" that seems to be an ECMWF product
but I'm not sure that ECMWF provides such a forecast product.
@gkikas-lgpz Thank you! We were already experimenting with simulated satellite data, but did not found it useful for Windy. Regarding simulated dbz: I am afraid that there is no such product. This is list of current ECMWF forecast products: https://www.ecmwf.int/en/forecasts/datasets/set-i
Sorry for the confusion
The actual product is instantaneous precipitation rate....see the link below which is basically the same as simulated radar. You have to scroll down a bit to find it.
It is included with with the new lighting forecast data in the latest model update.
The base reflectivity output from ECMWF I mentioned is in fact the instantaneous precipitation rate converted to radar dBZ values.
Could you add this product (instantaneous precipitation rate) to Windy please?
Just to clarify: It is Total Precipitation Rate (same as Instantaneous Precipitation Rate)
@rogerdoger Hi, unfortunately not. Only if there are more people requesting it, but I think that this layer would not be widely used.
That's a shame. I can't see the problem in adding it for those that would use it. As I mentioned above, it has advantages over the 3 hour precipitation.
Surely, the more choice for users, the better!
