Comparison of Microphysical Properties of Clouds in Two Regions Tropical With Distinct Ecosystems Using Satellite Data from CloudSat
The approach used in this work's methodology looks to represent the average microphysical structure of different types of clouds formed in two different ecosystems. The selected regions were located in the Midwest of Brazil (coordinates: 12-18 ° S and 46-58 ° W) and the South Atlantic Ocean (co...

The approach used in this work's methodology looks to represent the average microphysical structure of different types of clouds formed in two different ecosystems. The selected regions were located in the Midwest of Brazil (coordinates: 12-18 ° S and 46-58 ° W) and the South Atlantic Ocean (coordinates: 12-25 ° S and 9-30 ° W). In order to accomplish the proposed goal, data from CloudSat satellite from a period of approximately five years are used (from June 2006 to April 2011). The results show that there is little variation in microphysical structure between continental and maritime clouds in the studied regions. The mean droplet (ice particle) effective radius obtained in all the cloud types analyzed was 12.4 μm (71.9 μm) for maritime clouds and 11.0 μm (72.9 μm) for continental clouds.
