Blog - exploring climate data (part 3, old version)

edited February 2015 in Azimuth Blog

I put a version of Nadja's blog post on "the deterioration of climate data" on the wiki:

I edited her English, added links, and added a short section of links to discussions of the effects of missing data on HadCRUT4. Everyone - especially Nad - should take a look and see if they like this post.

Note: this version has been superseded and will not be posted to the blog. For a discussion of the new version, go here.

    Here's one possible explanation of the "increase of missing data": when new weather stations appear, they just appear. But when old stations disappear (or stop producing data) there's a mark for "missing data".

    This could be wrong, but it would explain the appearance of an increase in missing data without an actual decline in the number of stations.

    Blog - exploring climate data (part 3)

    Sorry John but I had already edited another thread at http://forum.azimuthproject.org/discussion/1501/how-good-is-climate-science-temperature-data/?Focus=12881#Comment_12881 Your copy of an older blog post is outdated. In particular as I wrote long time before the visualization can in principle be seen at: http://nad0815.github.io/climate/tempGlobe/. I write in principle since unfortunately the company Klokan technologies seems to change once in a while the underlying files of webgl earth, which may induce a nonworking of the visualization. I wrote to them already a couple of times and asked them kindly to stop that.

    Furthermore I had asked you in the comment to store the images at Azimuth. We are at the quota limit with our blog, so I prefer not to lure too much Azimuth readers to our blog.

    Please feel free to correct the english.

    I supplemented this post with your additions about the missing data.

    In fact the CRUTEM 4 data looks to me worse than bad. I am currently looking at the averages (which tells also something about the whole dataset and it seems since around 2005 the dataset as it is offered online is - I would say - not usable. I would have liked to show you the averages, but Klokan technologies changed today again their files, which also killed the average visualization, since I had written that into the same file. So either they come to terms again or I need to restructure fist.

    I missed though some comments on why they stopped posting their temperatures in 2011.

    around 2005 the dataset as it is offered online is - I would say - not usable.

    I meanwhile restructured and to be more precise: starting at 2008 the average temperatures look as if they are enormously shooting up and the anomalies start oscillating largely.
