<![CDATA[ECMWF Rain accumulation error]]>Hi,

I've noticed that the ECMWF model is not accurate regarding the sum of de rain proyected in some cases.

In this image, the number which indicates the sum of the rain in the period is different of the sum of the 3 hour forecast, for example for the town of Hierro Viejo.

Also, the rain acccumulation layer for the ECMWF model and the METEOBLUE model is the same also.

Thanks in advance!

Hello,

I checked yesterday and today again at same location. It seems you are right. There is a discrepancy between the Rain accumulation layer and the amount in the forecast table.

5.9mm in the Rain accumulation

8.7mm in the forecast table

Yesterday the discrepancy was even more important.

The case of Meteoblue is different because this non-gridded model does not dispkay weather maps. So the map that you displayed is that of ECMWF model
