VAP : Active Remotely-Sensed Cloud Locations (ARSCL)

Instrument Categories
Cloud Properties

The Active Remote Sensing of Clouds (ARSCL) VAP combines data from active remote sensors to produce an objective determination of hydrometeor height distributions and estimates of their radar reflectivities, vertical velocities, and Doppler spectral widths, which are optimized for accuracy. These data provide fundamental information for retrieving cloud microphysical properties and assessing the radiative effects of clouds on climate.
