Clouds with radar reflectivity values between Z_threshold_1 and Z_threshold_2 are categorized as "clouds with light drizzle" Units:dBZType:singleprecision floatingpoint scalar radar/lidar Liquid water categorization bits
This variable contains information on the presence and nature of the liquid water at each pixel. The information is in the form of an array of bits, each of which states either whether a certain type of data or categorized water clouds is presented The definitions of each bit are given in the definition attribute. Bit 0 is the least significant. Units:n/aType:byte array Definition: radar/lidar LWC from FoxBaediDrizzle ZLWC relationship
