Description

Microwave attenuation is directly proportional to cloud liquid water content (LWC) and can be calculated accurately from dual-frequency radar measurements. The dual-frequency radar attenuation approach, unlike Z-LWC approaches, makes no assumptions about the cloud drop size distribution. This poster shows that, by combining this simple physics and advanced mathematical inversion techniques, accurate retrieval of vertically resolved cloud LWC can be obtained using operational ARM Ka- and W-band cloud radars. We have applied the dual-frequency approach to retrieve microphysical properties of warm clouds using the ARM radar observations from 2006 to 2008. This poster will present the comparisons between the dual-frequency and the MICROBASE cloud retrievals.
