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

<p>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 <a href="https://wui.cmsaf.eu/safira/action/viewDoiDetails?acronym=CLAAS_V002_01">CLAAS-2.1</a> 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.</p> <p>CRAAS covers a region over Europe (30&deg;N to 60&deg;N and from 11&deg;W to 37&deg;E) and it extends from 2004 to 2017. The generated Joint Cloud Histograms (JCHs) of Cloud Top Pressure (CTP) and Cloud Optical Thickness (COT),&nbsp;<br> as well as the derived labeled data points of the cloud regime classification are available on a 1&deg;x1&deg; degree resolution and every 15 minutes.</p> <p>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: &#39;craas_jch_2004.v1.nc&#39;)&nbsp;<br> and those including the labeled data points of the cloud regime classification (example filename: &#39;craas_label_2004.v1.nc&#39;).<br> The files are provided in netCDF4 format, following the NetCDF Climate and Forecast Metadata Conventions-Version 1.8 (CF-1.8).</p>
