Description
We will report on various analyses of X-SAPR and C-SAPR data collected during the joint DOE/NASA field project MC3E (Midlatitude Continental Convective Clouds Experiment) carried out during May–June 2011 at the DOE ARM site near Lamont, Oklahoma. We have developed an attenuation correction for the X-SAPR data based on the differential phase method. Corrected X-SPAR reflectivity fields compare favorably to nearby KVNX NEXRAD data, except for areas where hail is identified. This underpins the difficulties of retrieving meaningful X-band data in hail regions.
We will also report on new activities involving a dual-wavelength (X-and C-band) Hydrometeor Identification algorithm. Also, we will report on results from a so-called blended rainfall algorithm using specific differential phase data at both X- and C-bands. Dual-Doppler derived air motion statistics along with hydrometeor types will be shown, aimed at developing suitable formats for comparing to ASR modeling efforts.
