2B-TAU

CloudSat Product Stats - Algorithm Developer Edition
Product Availability: Not available during Epoch 05 (E05).

The primary objective of the algorithm is to produce estimates of the optical depth (τ) and its uncertainty for each radar profile determined to contain cloud. An estimate of the column-average cloud effective radius is produced for each radar profile as well.
