  • Just a side comment (LHCII is for you only a special application for your methods, so this is probably not so interesting for you): Some community detection for you: There is another community mostly located in Arizona, which used serial time resol…
  • As far as an exact biennial (2-year) period, there may be something on the recent thread on tides: http://azimuth.mathforge.org/discussion/1480/tidal-records-and-enso/?Focus=12570#Comment_12570 You mean your comment with the period doubling? Ye…
  • Is seems NOAA actually has geomagnetic indices here and in principle you could download it and even look at a GIF animation, however I always get the error message: SPIDR cannot execute the requested action... Potential reasons: If you're using W…
  • Remark concerning the temperature collections: It seems that at least private collections like wundermap and awekas have also rather few stations in northern siberia and central africa. Like wundermap has on Novaya Semlya only one station (Malye K…
  • I wrote: The particle stream influences cloud formation and could thus among others in principle change the albedo and temperature. In this context and the context of the real climate notices I wanted to mention: The division of the atmosp…
  • I was searching for data and visualizations concerning magnetic indices like the aa index. I found links at NO AA ;). That is the links to the Laplace Institute on that page are broken. Moreover searching on the website like via search or looking at…
  • But I found their link to a discussion about day and night time temperatures interesting. This may indicate that there exist more detailed temperature collections than the CRUTEM (which provides only monthly averages).
  • thanks for the link. About the IPCC 2001 citation: I am not sure wether the solar forcing meant here is variations in radiation only and/or particle flows that is the realclimate blog post you linked to indicates that the particle aspect seems to b…
  • It’s just this deadline that’s giving me an ulcer. I think you should pay more attention to your health. Why not cancel the talk?
  • Others have mentioned the heliospheric cuurent sheet, which leads to this paper In the paper they introduce some "irregularity indices" λ_WN and λ_aa of "daily series of sunspot number WN and geomagnetic index aa as a function of increasing smo…
  • Paul, sorry but I think this problem hasn't been adressed adequately. I wrote in here: One thing one should look at in the context of biannuity though more carefully is surely that the earth in its orbit around the sun appears with its axis a …
  • That is true, but the value of t ranges from 1950 to 2000, so that this amplification is very slight, like 2 to 3% of the signal amplitude. I am not sure if this can be perceived visually amongst the fluctuations, but that is what the tool is fin…
  • When I attempted a machine learning fit to QBO, one extended trial ended up like this ???Shouldn't lead the term: tcos(6.192 + 153t) to an increasing signal? This isn't visible in the graphics (but then I don't know what the graphics is suppose…
  • I said: As I said I think it looks biannual. With that I mean the pattern. In particular I don't share the opinion about other periods. But actually you wanted a comment on the height of the extrasystole. For this one one would probably need t…
  • The other point by nad is important, and that is whether we could actually pick up a pattern and predict the extrasystole peaks in the future. As I said I think it looks biannual. Moreover in other comments I suspected that since it is so regul…
  • Is the ENSO/QBO index from literature reference [5]? Usually I have no access to nature articles. The two look indeed correlated. Is there a longer time scale? The QBO periodicity looks to me biannual with some irregularities, like a signal thats so…
  • I might just submit something that I worked on from before. Does it conform to the 4 winner ideas?: This Challenge focuses on building an application using themes based on the best topics from the first Ideation Challenge, combined with any…
  • As it seems you can even make 21 $ an hour at some fast food chains - here the report of a young women in denmark. In the US this seems to be however more difficult.
  • I had already written about that here. But of course it usually makes sense to repeat that kind of announcements. By the way do you know which types of data is the openNex data collection encompassing? I have problems to give a good meaning to that …
  • the CRUTEM 4 stations data visualization is now online. Caution it takes very long to load. CRUTEM 4 stations data is about 45 MB.
  • side remark: the island volcano Bardarbunga is rather well documented, as can be seen e.g. by this earthquake visualization (caution: takes rather long to load).
  • Just for the archive: http://www.volcanodiscovery.com/earthquakes/quake-info/38225/M5.1-Thu-6-Sep-Ural-Mountains-Region-Russia.html http://www.volcanodiscovery.com/earthquakes/quake-info/151787/M3.9-Mon-24-Dec--URAL-MOUNTAINS-REGION-RUSSIA.html htt…
  • I think all the global temperature records are pretty much different analyses of the same set of stations. The main independent alternative is satellite data (e.g. RSS). So you say it is not HADCRUT or some communication problem that the number…
  • For comparison purposes, Clive Best has constructed an interactive station browser here http://clivebest.com/world/Map-data.html He has date selection so you can see the progression over time. And Nick Stokes has his variation here…
  • You can have a more detailled look on what I mean exactly at this blog post on randform.
  • I forgot to list the URL for the stations data: http://www.cru.uea.ac.uk/cru/data/temperature/crutem4/station-data.htm File:http://www.cru.uea.ac.uk/cru/data/temperature/crutem4/crutem4_asof020611_stns_used.zip Be careful when trying to machine rea…
  • When I talk about oversampled networks in the U.S. and Europe, I’m referring to the densely populated regions, not northern Siberia … OK. and yes - strictly speaking everything east of Ural mountains on the mainland is even not really anymore E…
  • I looked now at the russian sources which were given at HADCRUT: http://www.cru.uea.ac.uk/cru/data/temperature/crutem4/station-data.htm The link at http://meteo.ru/climate/sp_clim.php is broken and the other link at http://meteo.ru/english/climate/…
