lwe_thickness_of_precipitation_amount_at_or_above_threshold m [ULAA]
Change Date: 20 May 2026, 12:45 a.m.
lwe_thickness_of_precipitation_amount_at_or_above_threshold m [ULAA] 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 X_at_or_above_threshold represents the accumulation of X considering only values where X meets or exceeds the threshold (inclusive). It must have a coordinate variable or scalar coordinate variable with the standard name of X to supply the threshold(s).

number_of_days_with_lwe_thickness_of_precipitation_amount_at_or_above_threshold m [ULAA] "Amount" means mass per unit area. 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_strictly_above_threshold|X_strictly_below_threshold|X_at_or_above_threshold|X_at_or_below_threshold is a count of the number of days on which the threshold condition is satisfied. A condition of the form strictly_above|below means the threshold value itself is excluded (strict inequality). A condition of the form at_or_above_threshold|at_or_below_threshold means the threshold value itself is included. A variable whose standard name has the form number_of_days_with_X relative to a threshold condition must have a coordinate variable or scalar coordinate variable with the 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".
