This product includes sensor measurement software provided cloud variables (zcb, vertical visibility, detection status).
Limitations: Sensor measurement software typically identifies liquid clouds well. However, do not identify all ice clouds. For more complete cloud typing and hydrometeor identification, the data user is referred to sups_joy_cln00_l4_class product in the HD(CP)2 data base.
