Is there a "New Zealand Effect" in Australian data? Quite possibly. The Torok and Nicholls network of stations which can be downloaded from the BoM ftp site, not yet adjusted to produce the 'official' BoM version, shows little warming.
The blue line is the 'official' BoM mean temperature, the black line is the mean for all stations combined using my patented normalization method, described in a previous post.
The minimum temperature (red and orange lines are the minimums) for the Torok and Read more [...] 2 com
Willis Eschenbach has written a comprehensive article on adjustments to temperature in Darwin, some increasing the rate of warming by as much as 5C/century. Thanks to readers I have the daily temperatures from the Torok and Nicholls network, and plotted their minimum, maximum and mean temperatures for Darwin. The rates of warming are 1.3C/century and 1.4C/century for the min and max respectively. Moreover, the T&N adjustments are too small to distinguish.
I must admit I don't understand Read more [...] 33 com
Continuing my preliminary look into the Torok and Nicholls Adjusted Network of Australian temperatures, I now focus on the mean monthly minimum temperatures. As shown in the previous post, maximum temperatures are flat from 1850 to the 1990s, only the minimums show global warming. The annual means usually shown are based on the average of the minimum and the maximum, so there is no point in examining anything other than minimum temperatures.
Above are the monthly minimum temperatures for the Read more [...] one
Digging deeper into the Australian Temperature Adjustments, below are data from 224 stations in the Torok and Nicholls network. It looks like most of the increase in Australian temperature in the last 150 years is due to a step-like increase in the mean annual minimum temperature since 1975!
CA examined the sometimes considerable adjustments of individual stations here and here. Steve also plotted up the raw station data. I don't know how he did the plots for 'before adjustment' as all the data Read more [...] 30 com
