<![CDATA[Rain or Snow ?]]>@administrators
@Developers
As the winter is coming (to the northern hemisphere) I want to mention a "problem" that maybe drive us to bad forecasts.
The ECMWF model is not separating rain or snow (is indicating precipitation in general),
but GFS separates rain from snow.
Take a look at the picture:
Today, in a place in east Greenland ECMWF gives negative temperature (-12C) and 12,3 mm of rain.
Of course in such temp. the precipitation it will be in the form of snow with a depth aprox. 12 cm
(in general 1mm of rain = 1 cm of snow).
On the other hand, GFS is giving 7,7 mm of precipitation BUT on the meteogram we see (correctly) the symbol of snow with a snow depth in cm.

It would be great if we have a "layers" option!
By now the only layers are the total clouds + rain (rain included as dots).

Interesting to see on the map how distributed precipitation? As I understand it the data is in the GFS and ECMWF?

as the color of the snowflake is similar to the background.
I suggest dark blue for the snowflake symbol.

PTYPE Precipitation type (ID: 260015 GRIB2) and
SF Snow fall (ID:144)
if those datasets are available to you.
