Brief Description

Description :

An instrumented air-craft with radars and other surface based instruments that help in better understanding of characteristics of monsoon clouds and interactions of clouds and aerosols. CAIPEEX has two components, viz. (1) Cloud-Aerosol interaction and (2) Precipitation Enhancement. Understanding of cloud-aerosol interaction is pre requisite for the second component. Aircraft observational programme has been proposed for the first component. The proposed experiment is planned to carry out in three phases. Phase I is devoted for intensive cloud and aerosol observations over different parts India during the period May- September 2009. In Phase II, precipitation enhancement experiment would be carried out by artificially seeding the clouds in 2010 and 2011. The analysis of the data will be carried out in phase III in 2011-12. In July 2018, CAIPEEX has started its Phase IV experiment for 120 days depending on availability of suitable clouds.
