Cloudy Intervals With A Chance Of UHIE
A little treat for paid-up subscribers in which I crunch mean and maximum daily temperature for all GHCNd stations with records stretching back >120 years
Back in the day the feature film first reel ran out, some crazy adverts played on the screen informing us of treats available in the foyer (including dancing hotdogs) and a smart lady walked down to the front with a little tray of sugary goodies strapped to her neck. I always went for a Kia-Ora, which I sucked on noisily (mostly on purpose) and sometimes got treated to a lolly with bits stuck to the surface.
Today I am going to treat those who have taken out a paid subscription by doing something terrifically tasty. I am going to run a KNMI query on the entire GHCNd dataset and ask for daily mean temperatures for every station on the face of the globe with records stretching back 123 years or more. The query will then crunch the overall annual mean from this matrix for those years with 95% data capture or better, converting everything into standard WMO anomalies.
This is what we may call ‘the big picture’, and rightly so for it should tell us what has actually been going on across the globe (well, the Northern Hemisphere mainly ‘coz that’s where the vast majority of weather stations are located) as opposed to what experts and the media tell us what has been going on, and as opposed to what gridded products from NOAA, NASA, Berkeley, CRU, Hadley Centre etc etc claim has been going on. They say raw honey is good for you, and this applies to raw temperature data!
