1.8 CF Standard Names: Number of Days With Surface Temperature Below Threshold (number_of_days_with_surface_temperature_below_threshold)

Record Label : number_of_days_with_surface_temperature_below_threshold

Record Title : Number of Days With Surface Temperature Below Threshold

CF Standard Name : number_of_days_with_surface_temperature_below_threshold

Record Description : The surface temperature is the temperature at the interface, not the bulk temperature of the medium above or below. The surface called "surface" means the lower boundary of the atmosphere. A variable whose standard name has the form number_of_days_with_X_below|above_threshold is a count of the number of days on which the condition X_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".
