Yes, exactly. And, just to complete the picture, possibly even a to apply fourth operation to calculate a climatological average over e.g. 30 years. In practice, this is of course much simplified if one uses monthly mean temperature data as input because the operations that is actually performed would be described by the cell method "time: range within years time: mean over years". But this would be an incomplete description of the data.
