Dataset containing vertical profiling of cloud radar. The external dataset can be downloaded from https://cloudnet.fmi.fi/. For instructions on how to download from Actris see: https://docs.cloudnet.fmi.fi/api/data-portal.html. Note that the parameters are case sensitive which should be used as in the examples. The arguments must be in lower case for example: “&site=cabauw”.

Sonic anemometer observations from the two RWS stations FL47 and FL48 at Lake IJssel, derived from 50 Hz resampled data

A gridded 50-member ensemble of precipitation forecasts that are created using a tree-based machine learning method, quantile regression forests, and inputs from the deterministic Harmonie-Arome (HA) forecasts. The target data set is rain-gauge-adjusted radar data that is upscaled by taking 3x3 km means and then a maximum is taken in a 7.5 x 7.5 km box. Inputs to the machine learning model include HA precipitation, and indices of atmospheric instability. Spatial and temporal dependencies are restored using the Schaake Shuffle. Forecasts are available during the extended summer period (mid-April to mid-October). Hourly forecasts are issued 4 times per day (00, 06, 12 en 18 UTC) for 48-hours into the future.

Daily files of wind profiles (raw data) between 11 and 300m altitude, measured by the ZephIR 300M wind lidar (ZX firmware), obtained during a measurement campaign by KNMI at the Cabauw site from February 2020 to June 2020.
