Cirrus Clouds, Citation Research Aircraft, Radar


The instrumented North Dakota Citation Research Aircraft and the Cloud and Precipitation Radar with discrete Hydrometeor Detection (CPR-HD), a high-resolution radar, obtained concurrent measurements of anvil cirrus clouds during seven research flights over Cape Canaveral, Florida in the summer of 2015 (CAPE2015). The Citation Research Aircraft is equipped with instruments for measuring GPS location and altitude, pressure, temperature, dew point temperature, and wind velocity, as well as a set of cloud physics instruments. The CPR-HD is a C-band, dual-polarization, Doppler radar with the capability of switching between two waveforms, a low-resolution beam and a high-resolution beam. Two radar reflectivity datasets are included: an observed radar reflectivity factor data set from the CPR-HD and a derived equivalent radar reflectivity factor dataset obtained from microphysical probes onboard the Citation Research Aircraft.
