Disdrometer Observations and Calculations of Radar Variables

The following results are based on the meausrements on 13 May 2005 by a disdrometer deployed at KFFL.
rain variables
Rain variables (rainfall rate, totcal number concentration, and mean volume diameter) calculated from disdrometer measured DSDs.
Rain variables (reflectivity, differential reflectivity, correlation coefficient, specific differnetial phase, pecific attenuation, and specific differential attenuation) calculated from disdrometer measured DSDs.

Radar Echo Classification

radar echo class
Result of radar echo classification based on reflectivity, differential reflectivity, and correlation coefficient.
