number_of_days_with_lwe_thickness_of_precipitation_amount_at_or_above_threshold 1 [UUUU] The construction "lwe_thickness_of_"X"_amount" or "_content" means the vertical extent of a layer of liquid water having the same mass per unit area. The abbreviation "lwe" means liquid water equivalent. "Precipitation" in the earth's atmosphere means precipitation of water in all phases. A variable whose standard name has the form number_of_days_with_X_at_or_above_threshold is a count of the number of days on which the condition X_at_or_above_threshold is satisfied, where the threshold value itself is included. It must have a coordinate variable or scalar coordinate variable with the a standard name of X to supply the threshold(s). It must have a climatological time variable, and a cell_methods entry for within days which describes the processing of quantity X before the threshold is applied. A number_of_days is an extensive quantity in time, and the cell_methods entry for over days should be "sum".
