Abstract
Comparison of reflectivity data of radars onboard CloudSat and TRMM is performed using coincident overpasses The contoured frequency by altitude diagrams CFADs are constructed for two cases a only include collocated vertical profiles that are most likely to be raining and b include all collocated profiles along with cloudy pixels falling within a distance of about 50 km from the centre point of coincidence Our analysis shows that for both cases CloudSat underestimates the radar reflectivity by about 10 dBZ compared to that of TRMM radar below 15 km altitude The difference is well outside the uncertainty value of ~2 dBZ of each radar Further CloudSat reflectivity shows a decreasing trend while that of TRMM radar an increasing trend below 4 km height Basically Wband radar that CloudSat flies suffers strong attenuation in precipitating clouds and its reflectivity value rarely exceeds 20 dBZ though its technical specification indicates the upper measurement limit to be 40 dBZ TRMM radar on the other hand cannot measure values below 17 dBZ In fact combining data from these two radars seems to give a better overall spatial structure of convective clouds
