USHCN adjustments plotted for USA and States
There has been a lot of interest in USHCN adjustments. Paul Homewood has been tabulating data from various states, most recently Ohio. Steven Goddard has been getting publicity with various flaky graphs. In criticising one of these, I posted a plot of average US adjustments. In doing so, I followed SG's practice of a simple average across the USA. It would be better to use some kind of area weighting.
Zeke Hausfather has been writing a series at Lucia's, and there have been various posts at WUWT.
So I thought it would be useful to post a complete series of plots of the effects of USHCN adjustments on the individual states, and then an average of these weighted by state area. This should give similar results to gridding. So there is an active plot below the jump. Note that the results are in °F, which seems to be traditional for USHCN.
