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 ...

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...

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...

Four cloud cover parameters are retrieved continuously from sky temperature measurements by a scanning infrared radiometer (NubiScope). These parameters are resp. total, low -, middle - and high level...

The Cloud Physical Properties (CPP) algorithm is being developed at KNMI to derive cloud, precipitation and radiation products from satellite instruments such as SEVIRI onboard the Meteosat Second Gen...
