*Daily means for each station are calculated using the MIDAS Open dataset, and are 15-day rolling means centred about the day in question. Daily means are calculated for each calendar day, and are only accepted if there are 27 or greater observations in the period 1991-2020, out of a possible 30. The rolling mean is then calculated as a mean of the individual daily means (weighted by number of obs), from the day in question and the 7-days either side.
