Abstract:
Because clouds play an important role in the Earth's radiative budget and on Earth's climate, the aim of this study was to understand the occurrence and characteristics of medium thickness clouds using satellite data. Partial results from a study conducted between December 2019 – February 2021 are presented. Hourly data from the Clouds and the Earth's Radiant Energy System (CERES) database (i.e., SYN1DEG-1Hour) were extracted and used for analysis of a series of macrophysical and microphysical cloud parameters (e.g., cloud cover fraction, cloud top temperature, cloud base temperature, cloud top pressure, cloud height, cloud optical depth, liquid water path, ice water path, cloud water radius and ice water radius). We studied the cloud vertical classification and their composition (water droplets or ice crystals). Măgurele Center for Atmosphere and Radiation Studies (MARS, 44.35°N, 26.03 °E), located south western Bucharest, 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 in-depth researches for understanding the formation and evolution of clouds.
