The CloudSat Mission
CEE: 6900-Environmental Application of Remote Sensing

This heat energy is what drives the planet’s climate and weather
The NASA CloudSat mission uses radar in a unique way to discover more about the interior of clouds and hence resolving much of the unknowns about clouds.
the Earth System Science Pathfinder Program sponsored missions are designed to address unique, specific, highly focused scientific issues, and to provide measurements required to support Earth science research
Radar Intensity is measured by a reflectivity
This is to account for very large and very small numbers
Other CPR Properties

This heating exerts a dominant influence on the large-scale circulation of the atmosphere as well as on deep convective cloud systems.
Cloud Radiative Heating (K/Day) for various thickness of clouds:
For example, high cloud layers heat the tropical atmosphere by more than 80 W m−2 (relative to clear skies)
