CRAAS: Cloud Regime dAtAset based on the CLAAS-2.1 climate data record

The Cloud Regime dAtAset based on the CLAAS-2.1 climate data record (CRAAS) is a dataset of cloud regimes derived from cloud properties from the CLAAS-2.1 climate data record. Such a cloud regime dataset can provide detailed insight in the cloud climatology over the region of interest and also in climate monitoring through the concept of the cloud regimes. CRAAS covers a region over Europe (30°N to 60°N and from 11°W to 37°E) and it extends from 2004 to 2017. The generated Joint Cloud Histograms (JCHs) of Cloud Top Pressure (CTP) and Cloud Optical Thickness (COT), <br> as well as the derived labeled data points of the cloud regime classification are available on a 1°x1° degree resolution and every 15 minutes. Two sets of yearly files can be found in the dataset. Those containing the generated JCHs from the CLAAS-2.1 climate data record (example filename: 'craas_jch_2004.v1.nc') <br> and those including the labeled data points of the cloud regime classification (example filename: 'craas_label_2004.v1.nc').<br> The files are provided in netCDF4 format, following the NetCDF Climate and Forecast Metadata Conventions-Version 1.8 (CF-1.8).
