Snow extent North America
Talk on WUWT about snow cover tripped a look at the datasets indicated there.
The weekly data turns out to be corrupt, something is radically wrong with the sampling, more than an erratic timebase. Tried twice to fix it, no go.
I wanted gain some understanding so I had a look at the monthly North America only data. This proved more malleable but I am still wondering a little whether it is right.
Here is the resultant graph. If you want the data or justifications for what I have done, ask.
I’ve included inverted UAH for USA 48 states, the snow data is for North America, excluding Greenland. This is quite interesting because the UAH dataset starts very cold and I had long wondered why. Perhaps it was. Nice when data matches.
