Climate

I have updated the weather box using Pogoda.ru.net but recently it has been reverted a couple of times. Despite explaining in the edit discussion, the revision has been reverted and I would like to explain here in the talk page about it.

Using the World Meteorological Organization data as seen in the difference in this revision and my revision is not proper in this case for a couple of reasons.

  1. The Pogoda.ru.net uses data coming from WMO stations (e.g for Ganja in Azerbajian, both Pogoda and one of the official sources that is a member of the World Meteorlogical Organization, DWD use the same values. For locations in Russia and the CIS, they have data originating from WMO stations. I read the FAQ and they mention that data comes from official sources (NOAA). That makes it reliable even though the source is unofficial.
  2. With regards to the first point, because the data is originally from official sources, these official sources (e.g NOAA) are the ones responsible for quality check, not for sites that publish these info that was originally from the official source.
  3. The source may be unofficial but it has way more data than the WMO link which only gives mean temperatures and precipitation. It also uses data from 1981–2010 (see their FAQ) which is much more representative of today's climate than the old 1961–1990 data. Also, in that revision, it is wrong to use mean temperatures from a different period of reference compared to average high and low. It is wrong to use mean temperature from 1961–1990 and use average high and low from 1981–2010 since the values will differ. Official data is extremely difficult to find in many places in the world.
  4. Even if unofficial, they mention the way in which the data is calculated (metadata). This makes it reliable compared to the WMO source where it does not mention it; even mistakes are found on the WMO site. Ssbbplayer (talk) 18:28, 16 October 2016 (UTC)


  1. Which WMO station did Pogoda's data for Tbilisi come from? You provided a link to Progoda's file archive, but their 2010 normals do not have Tbilisi. As for "locations in Russia and the CIS," Georgia's not in the CIS. As far as using NOAA as a source goes, NOAA only provides data thru 1990 for Tbilisi.
  2. As mentioned above, NOAA only provides data thru 1990 for Tbilisi — which I'd be fine using
  3. We can use all temperatures from Pogoda to avoid mixing sources. But I am not in support of using the mystery precipitation data from Pogoda. As far as official data goes, thankfully it is available for Georgia. Speaking of official data, the actual WMO affiliate in Georgia reports an average annual precipitation of 506 mm (19.9 in) in a very recent release, a value much closer to the WMO normals.
  4. I agree. They also mention they take no responsibility for the accuracy of data provided on their website.

Since you have so much faith in Pogoda's unsourced data, we can use temperatures from Pogoda and precipitation from WMO and be done. Graeben (talk) 22:17, 16 October 2016 (UTC)
