Precipitation - daily rainfall sum and depth of snow cover from network of voluntary observers
Technical documentation
Introduction
The KNMI publishes pre-controlled 24-hour precipitation data from weather stations in the KNMI climatological precipitation network. This dataset provides the 24-hour (08-08 UTC) precipitation amount, including measurements of rainfall and snow cover depth, collected from a network of voluntary observers.
How to use this dataset
The columns in this dataset are respectively: Station-Id, Name, X, Y, date/time, RD (rain), S (snow).
With additional explanation for columns X, Y, RD and S:
X, Y:
These are coordinates from the Rijksdriehoekscoordinaten coordinate system.
The exact location has been masked by reducing precision. In order to get a valid coordinate, the value from the column should be multiplied with 1000.
RD (rain):
[empty]: measurement lost
0: no rain
1 - 9998: rain in 0.1 mm
9999: dummy (not in use anymore)
S (snow):
0: no snow
1 - 996: snow depth in cm
997: snow depth less than 1 cm
998: discontinuous snow cover
999: piled snow
