Record Title : Spell Length of Days With Air Temperature Above Threshold

CF Standard Name : spell_length_of_days_with_air_temperature_above_threshold

A spell is the number of consecutive days on which the condition X_below|above_threshold is satisfied. 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, and a cell_method entry for within days which describes the processing of quantity X before the threshold is applied. A spell_length_of_days is an intensive quantity in time, and the cell_methods entry for over days can be any of the methods listed in Appendix E appropriate for intensive quantities e.g. "maximum", "minimum" or "mean".
