Also new on the map this winter are the SNOWGRID snow depth data! These can now be found next to the tab for the sunshine forecast under "Snow depth". The Central Institute for Meteorology and Geodynamics (ZAMG, Austrian Meteorological Service), which developed the SNOWGRID model, has only recently started offering the data in a format that can be integrated into the map. The data itself has not changed, only the colors and the presentation have been restyled a little. As with the new snow and sunshine forecast, the CR spots can be displayed simultaneously with the map overlay and filtered according to the number of stars, for example.

SNOWGRID in a new look
Change in snow depth in the last 24 hours. While it is still snowing in the south, the snow cover in the north is settling quite significantly.

The PowderGuide weather service is starting the season. As usual, you'll find a preview and short text forecast on the homepage and our PowderMap in the weather section, which you can use to navigate to ConditionsReports, text forecast, fresh snow and sunshine forecast.
Total snow depth - model domain ends in eastern Switzerland, already considerable snow depths, especially in the southeast.

SNOWGRID is based on the high-resolution INCA precipitation forecast from ZAMG. INCA can also forecast temperature and wind and this data is also incorporated into SNOWGRID, as are snow depth measurements from weather stations and radar data. SNOWGRID also takes into account the heat content and, related to this, the settling of the snow cover, as well as the lowering of the snow line due to precipitation cooling in narrow valleys. This means that there are also negative values with new colors (shades of green) in the snow depth changes, which can be displayed for the last 24, 48 or 72 hours.
SNOWGRID has a grid point every 100m, for which the snow depth and the snow depth change of the last few days are calculated. This means that our map always displays a value for an area of 100x100 square meters. This also means that small-scale fluctuations - such as those constantly encountered when skiing - are not resolved. Local wind effects - also very important when skiing - are not taken into account either, as this is very complex to model. SNOWGRID is therefore not suitable for checking how much snow there is on individual slopes. However, it gives a pretty good overview of the general snow situation in different regions. More information about the difficulties of precipitation measurements in high mountains and SNOWGRID can be found in this article.

If you look at the snow depths on the PowderGuide.com map, you'll notice: There is never snow west of Engelberg. This is of course not true, but unfortunately this is where the SNOWGRID model domain ends. This means that there is simply no more SNOWGRID data here.
Our remaining weather data is also from ZAMG and we would like to take this opportunity to thank them for their many years of pleasant cooperation! If you now extend SNOWGRID to the Western Alps, dear ZAMG, then we would be perfectly happy!

World of Science | How much did it really snow?
Lea Hartl • 01/16/2017
Ever since we got the SNOWGRID maps on PowderGuide, we've been getting questions about their accuracy: Why is there much more snow here in my favorite forest slope than on the map? SNOWGRID says there's two meters of snow in Ticino, but my buddy says there's nothing at all? Below we provide some insights into the complex world of precipitation measurement, the efforts of ZAMG to record snow as accurately as possible and why it still doesn't always work.
