Description

This data set provides high-resolution maps of surface weather in the Netherlands based on ground-based observations. An innovative interpolation is used which statistically blends weather observations from the KNMI network, citizen weather observations from the wow.knmi.nl network and static information like land cover type and distance to the coast. This statistical blend results in weather maps which have higher spatial detail and higher local accuracy than maps based only on our official network, but the historical perspective of the maps is shorter. The dataset provides a best estimate and a quantified uncertainty estimate of the local weather. Currently, this service is provided for air temperature, 10 m wind speed and relative humidity. The dataset should be regarded as a Beta release.
