Meteorologists know that the instrument record is broken
Well, at least the ones who know what they're doing.
Two years ago, we discussed the problem of time-response with different types of instrumentation and how the modern, fast-responding instruments inherently produce more spikey data.
Yesterday, Pierre Gosselin blogged on the German newspaper interview with veteran meteorologist Klaus Hager, a lecturer at the University of Augsburg.
For eight years I conducted parallel measurements at Lechfeld. The result was that compared to the glass thermometers, the electronic thermometers showed on average a temperature that was 0.9°C warmer. Thus we are comparing – even though we are measuring the temperature here – apples and oranges. No one is told that.
