Term: **number_of_days_with_lwe_thickness_of_precipitation_amount_at_or_above_threshold**

Unit: 1

Unit ref: UUUU

AMIP:

GRIB:

"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. "lwe" means liquid water equivalent. A variable whose standard name has the form number_of_days_with_X_at_or_below|above_threshold is a count of the number of days on which the condition X_at_or_below|above_threshold is satisfied. 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".
