'integral_of_Y_wrt_X' means int Y dX. The data variable should have an axis for X specifying the limits of the integral as bounds. 'wrt' means with respect to. Air temperature is the bulk temperature of the air, not the surface (skin) temperature. The air temperature deficit is the air temperature threshold minus the air temperature. Its integral with respect to time is often called after its units of 'degree-days'.
