 179,\Atmosphere\Clouds,,,Cloud amount,"Fraction of the sky covered by clouds of a particular type or combination. It can refer to a genus, species, variety, layer, or a certain combination of clouds. Also, see 'cloud cover'."
 180,\Atmosphere\Clouds,,,Cloud cover,"The amount of sky estimated to be covered by a specified cloud type (partial cloud amount), or by all cloud types (total cloud amount). In either case, the estimate is made to the nearest okta (eighth) and is reported on a scale which is essentially one of the nearest eighth, except that figures 0 and 8 on the scale signify a completely clear and cloudy sky, respectively, with consequent adjustment to the adjacent 1 and 7 okta intervals."

Cloud hydrometeors refer to liquid and/or ice cloud particles. For liquid phase cloud, the effective radius is defined as the area weighted mean radius of liquid water drops, assimilated to spheres of the same volume. The effective radius of cloud ice particles has been defined in literature in different ways. Clear and detailed definition should be provided as how this parameter is derived."
