sensor_latitude | float |  | [degree_north] | latitude of the instrument
sensor_longitude | float |  | [degree_east] | longitude of the instrument
sensor_altitude | float |  | [m] | altitude of the instrument above mean sea level
altitude | float | {vertical} | [m] | altitude of the measurement
cloud_type | int8 | {time, vertical} |  | cloud classification type; enumeration values: clear_sky (0), cloud_droplets (1), drizzle_rain (2), drizzle_rain_cloud_droplets (3), ice (4), ice_supercooled_droplets (5), melting_ice (6), melting_ice_cloud_droplets (7), aerosol (8), insects (9), aerosol_insects (10)
cloud_type_validity | int8 | {time, vertical} |  | detection status
cloud_base_height | float | {time} | [m] | cloud_base_height
cloud_top_height | float | {time} | [m] | cloud_top_height
index | int32 | {time} |  | zero-based index of the sample within the source product
