EarthCARE CPR  

Definition

  • CPR is a nadir-looking active instrument (94 GHz) of JAXA and NICT (joint development), Tokyo, and a core instrument of EarthCARE. The objective of the CPR is to provide vertical profiles of cloud structure along the subsatellite track to obtain micro- and macroscopic properties of clouds. • Detect radiatively significant ice clouds [extinction (alpha) >0.05 km-1] alpha radar sensitivity of -38 dBZ (10 km horizontal integration) alpha 500 m vertical range resolution • Identify precipitation and vertical motion: a) alpha Doppler measurements, b) accuracy 1 m/s. This provides information on convective motion (en)
