    Wow, just for me?

    What on earth happened from 1972-1973? Nothing, and then everything.

    Watching the animation is mesmerizing. It’s fun to watch countries come in and out; China comes and goes a couple times.

    Yeah, it brings up all sorts of interesting questions …

    Where did the WWII Germany/Poland data come from?

    You can expect China to drop in and out at least around the Cultural Revolution,
    but what’s up with India?

    And, totally agree, the 1972 gap is jarring.

    Its seems odd that SYNOP stations in GSOD are superabundant in recent decades in even while the CLIMAT stations become sparse in GHCN.

    Still need to get more organizational info on GSOD (and ISH?)

    Yeah, i thought of the cultural revolution too.

    India – Maybe they are trying to sell the data from the missing periods? I think that sort of thing is still an obstacle when compiling these databases. I don’t know.

    I love how Zimbabwe gets all lit up at some point; it’s striking because some of the neighbors are empty.

    The SYNOP/CLIMAT thing is as expected. Remember that GHCN data only started coming from CLIMATs in the 1990s.

    I still have no idea how GSOD or ISH are put together, or what the relationship between the two are. Mainly I’m too lazy to find out.

    I don’t think anybody’s tried to do what you’re trying to do here, besides Spencer’s thing with ISH. I think it’s worth a short paper somewhere.

    Come to think of it, has anybody published much of anything using GSOD? Let’s see…
    Ellis et al “How often does it rain over the global oceans?” GRL 2009 comes up, using precip data.

    Rinke et al “Regional characteristics of Arctic temperature variability: comparison of observations with regional climate simulations” Climate Research 2010 used GSOD temperatures

    don’t see much else. Maybe I need a better search term.

    It’d need a bit more meat before it’s publishable. I wonder what you could do. I’m sure you have your ideas going forwards. My pet idea was always to use this sort of data to test GISTEMP’s interpolation over sparse areas. I’d also want to see QC and homogenisation explored; I think synop data is known to be somewhat error prone. Probably washes out in the global mean, but there’s more to life than just that.

    I don’t think there are any “WWII Poland” data in this database, stations designated as Polish were in reality placed in pre-war Third Reich (in Eastern Prussia, Silesia and Pomerania), like Breslau/Wroclaw airport station.

    You problably noticed that GHCN database has a WWII gap for pre-war Polish stations, like Krakow and Warszawa. Frankly I don’t know why (this situation can be traced back to the Jones 1986 dataset), since most of these stations continued observations during the war, and the data were not lost. Maybe Polish NMS hadn’t published them yet, or maybe Jones et al decided that they were unreliable.

    Doh! So obvious once it is pointed out! Thanks!

    There are people who may know more (pdjakow, I know you’re lurking here!), because they work in the Institute of Meteorology and Water Management, i.e. the Polish NMS, and they know all the gory details about how this part of the Rest-of-World works, how we code and send SYNOPs and CLIMATs, and how our raw data look like.

    BTW, as an OT curiosity I can tell you that Polish parliamentary Commission for the Environment was some time ago fed with the Chiefio/Watts/d’Aleo “dying of thermometers” bulls^%t by one of our climate “experts” (a quaternary geology prof), and they seemed to believe it. And that’s why I find Mr Mosher’s assertion that their baseless accusations (and lack of public retraction/apology) “doesn’t matter” disingenuous.

    Sorry to hear it.

    And that, Michael Tobis, is why it is dangerous to leave such people unanswered.

    I’m intrigued by lurkers who know things. You’re allowed to open your mouths and give guidance.

  10. 2010 July 9 at 5:02 pm

    Encouraged.

    I freely acknowledge my incompetence and ignorance … but I am willing and able to learn!
