@The CAMPR operates at 13.8 GHz that is just the same as the frequency of TRMM PR, and makes down-looking rainfall observations (similar to TRMM PR). The CAMPR has spatial resolutions and the sensitivity much higher than those of TRMM PR, and has functions of multi-polarization and Doppler observations. Therefore, comparisons of TRMM PR and CAMPR data obtained from simultaneous observations provide a way to validate and evaluate the TRMM PR and its rain retrieval algorithms. Figure shows that the CAMPR observation gives higher spatial resolution and sensitivity, and that you can find a good consistency between them.
