Cloud-free and cloud-modified UV index data for an area covering the Benelux for each quarter of an hour from 03:00 UTC up to and including 21:45 UTC, both in the usual non-dimensional unit, and given...

This dataset contains backscatter profiles from the CHM15k ceilometer, a single-wavelength, automatic operating at 1064 nm. It includes daily uncalibrated, unvalidated data reported by the instrument ...

This dataset contains calibrated attenuated backscatter profiles from the CHM15k ceilometer, a single-wavelength, automatic operating at 1064 nm. It includes calibrated, unvalidated daily aggregated f...

This dataset contains backscatter profiles from the CHM15k ceilometer, a single-wavelength, automatic operating at 1064 nm. It includes uncalibrated, unvalidated data reported by the instrument at 33 ...

This dataset contains calibrated attenuated backscatter profiles from the CHM15k ceilometer, a single-wavelength, automatic operating at 1064 nm. It includes calibrated, unvalidated files for 33 sites...

Degree days are determined by the effective daily mean temperature (Teff). Teff is calculated with the daily mean temperature (TG) and the daily mean windspeed (FG). Teff = TG - 2/3 * FG. Degree days ...

This dataset contains cloud condensation nuclei counts (expressed in counts/cm3) and the particle size distribution (top of bins are 0.75, 1.0, 1.5, 2.0, 2.5, up to 10 microns), expressed in counts/s ...

2-dimensional clouddata (IR brightness temp. and cloudmask) and cloudcover (total, high, middle and low) derived from sky brightness temperatures recorded with a scanning pyrometer. For more informati...

Hourly synoptic in-situ observations are collected from operational monitoring stations in the North Sea. The data are subjected to quality control and, if needed, adjusted. Observed variables include...

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.f...
