Dear all,

I would like to know what exactly is the unit of "m of water equivalent" for snowfall.

I know that for Snow depth I need Snow density to convert Snow depth m of equivalent water to meters, but what about Snowfall ? I need it in m, not in m of equivalent water.


Hope to have some feedback soon

Kind regards

Joana

    Snowfall correspond to the mass of snow that has fallen to the Earth's surface.

    It is expressed as such in m of water, which is equivalent to 10^3 kg/m2.

    Details available from the ECMWF parameter database at https://apps.ecmwf.int/codes/grib/param-db/?id=144

    Hope this helps!

      Thank you Anabelle,
      I was aware of the units being in "m of water", but I need to convert it to "m". So what you are saying is that I should divide by 1000kg/m3 ??
      Thanks

    Hi Joanna,

    For the sake of completeness, please see Patricia's reply: How to convert snowfall "m of water equivalent" to "m"

    Thanks,
