I felt the need to include a guide as to the numbers of station series that are going into the new (homogenized) areal anomalies, since these vary with time - in contrast to those based on your old annual series. You may think that the station numbers information is not required - let me know what your opinion is on this. In your original listing of ideas for plots, you suggested a colour plot of: "My" rural "Their" rural "My" urban "Their" urban Now that we have included the gridded anomaly series, it provides a kind of datum line to both of the attached plots. Do you still think that there is a need for the colour comparison just listed? It is no big job if it is still required. Finer points: You will see that the station numbers line in the rural stations plot starts before the plot of areal anoms. - based on the new (homogenized) series. This is because I imposed a minimum threshold of 20 station values for there to be an areal average produced. If there are no more changes to these analyses for the moment, I will look at the Armagh job tomorrow.
