From the Sentinel-5p TROPOMI L2_CLOUD RPRO 1.0.0 data, (November 2017 - begin May 2018), the ROCINN-CAL cloud top height and ROCINN-CRB cloud height were compared with the ground-based cloud target classification measurements from the CLOUDNET database (http://www.cloud-net.org/), obtained within the same time period. Clear correlations are established. The CAL cloud top height is lower than the CLOUDNET height by ~0.5-1 km and the CRB cloud height is lower than the CLOUDNET mid-height by 0.3-0.5 km.
