GHCN Monthly data portal. Not monthly data which would be cumbersome, but annual average. This is useful for plotting and trends. There is a trial below. Each link leads to the NOAA GHCN station summary, as before, but the radio button brings up a page with a table of the annual averages, along with a brief metadata and a map the station is in the middle.
There is a table for unadjusted data, and below for adjusted. Both are then repeated in CVS format, for import into Excel. The table of links is searchable Ctrl-F , and can take a while to load. I'll probably add a graphing and trend calculation capability. In calculating the annual averages, I eliminated years with less than 9 months data. I also before removed data with flags indicating unreliability.
Then I calculated the simple average of the infilled data. Email This BlogThis! Central Australian warming. I've been arguing again, at Climate Etc. Blogger Euan Mearns has a guest post in which he claims to demonstrate that stations within km of Alice Springs show no warming.
I'll post about it here, because it illustrates the averaging fallacies I've been writing about regarding Steven Goddard and colleagues also here. And also because "Alice Springs" is one of those words naysayers sometimes throw at you as if no further explanation is required like Reykjavik.
People who do that generally don't know what they are talking about, but I'm curious, since I've been there. There are actually two issues - the familiar time series of averages of a varying set of stations, and anomalies not using a common time base. I'll discuss both. The stations are obtained from the GISS site. If you bring up Alice Springs, it will indicate other stations within a radius of km. My list was 29, after removing repetitions.
