Abstract:
Stratocumulus clouds, low level clouds usually not associated with precipitation, represent one of the key components of the Earth's radiative balance because it generally reflects the incident solar radiation (i.e., high cloud albedo values). In this presentation, partial results from a study conducted between December 2019–February 2021 are presented. The aim of the study was to understand the occurrence and characteristics of stratocumulus clouds using satellite data supplemented with ground-based lidar measurements. Hourly data from the Clouds and the Earth's Radiant Energy System (CERES) database (i.e., SYN1DEG-1Hour) were used. A series of macrophysical and microphysical cloud parameters (e.g., cloud cover fraction, cloud types, cloud geometrical depth, cloud top temperature, cloud top pressure, cloud height, cloud optical depth, liquid water path) were extracted from the CERES database for a region in south western Bucharest, were the Măgurele Center for Atmosphere and Radiation Studies (MARS, 44.35°N, 26.03 °E) is located. MARS was chosen as a study area because of the suite of remote sensing instruments (e.g., ceilometer, cloud radar, microwave radiometer) installed at this site that can be used to further understand the stratocumulus clouds.
