Abstract:

The Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) is a joint mission between NASA and the French space agency Centre National d’Ìätudes Spatiales (CNES) that analyzes aerosol particles suspended in the Earth‰Ûªs atmosphere. Researchers use visualized CALIPSO data to track the global distribution, dispersion, and source of aerosols. However, the current visualization tool for displaying CALIPSO data does not support needed features for tracking aerosols such as selecting areas of data and sharing those selected sections, making it difficult for researchers to track specific airborne objects. Adding these necessary features to the current CALIPSO visualization tool is difficult, as the tool is written in Interactive Data Language (IDL), a proprietary and obscure language, and writing additional features for the tool would require a specialized development team. For the 2015 summer term, our team was focused on the development of the Visualization of CALIPSO (VOCAL) Python program. VOCAL will serve as the successor to the current visualization tool for CALIPSO data. It follows a previous DEVELOP team‰Ûªs work and implements a number of new features and functionalities to more easily identify the sources of aerosols and their impact on Earth‰Ûªs climate.
