1B-CPR

CloudSat Product Stats - Algorithm Developer Edition
Product Availability: Full mission availability except for anomalies and maneuver data gaps.
1B-CPR measures the backscattered power as a function of distance from the radar. The backscattered power is sampled every ~240 m; there are 125 range bins, for a total window of 30 km. The raw, Level 0 data is converted to calibrated Level 1B data using pre-launch and in-flight calibration measurements.
