Using TempLS on an alternative land temperature data set - GSOD.


  1. Roy Spencer's ISH project is also relevant, in the same way. Roughly speaking, the ISH is complementary to the GSOD, but shows 4 daily measurements, instead of a daily mean. I think.

    What do you mean by 'looser'?

    Speaking of thankless labor, I suppose at some point, somebody could build up the inv file for the extra stations. The satellite index shouldn't be too hard; the rest could maybe be left as dummy values.

    At that point, I think the bloggers would have made something that the professionals would actually want to use.

  2. oh, and I absolutely love that the Russell panel went and did their own calculation. Unexpected, but awesome. You don't need to copy somebody else's code to do something for yourself.

  3. Good! Good! And I'm happy to take feedback. Let me know about processing issues. I'll take another look at the inv/mean station matching. I thought I had caught all of those running GISTEMP. Sorry about that.

    Comment: You should use the same scale on your side-by-side charts

  4. Ron,
    Thanks for the suggestion - I've rescaled the side by side plots.
    CE, by looser I meant mainly that in GHCN for each inventory line there is data, and for each data, an inventory entry. That's fixable. But GSOD has also, for example, the missing year 1972 etc, which meant I had to compare only back to mid 70's. And I expect that there is less QC on GSOD (but I may be wrong).

  5. I think less QC on GSOD is a safe assumption.

    I don't think GSOD is globally useful before 1973, based on the maps Ron made. But maybe some specific regions.
