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...

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...

On Bonaire, Saba and St. Eustatius hourly fully automated synoptic in-situ observations are performed. The data are not validated. Measured are temperature, cloud cover and visibility, precipitation, ...

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...

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...

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...

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 ...
