spell length of days with lwe thickness of precipitation amount below threshold
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 spell is the number of consecutive days on which the condition X_below|above_threshold is satisified. A variable whose standard name has the form spell_length_of_days_with_X_below|above_threshold 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
