In my previous post Dial “M” for mangled – Wikipedia and Environment Canada caught with temperature data errors. we identified some problems with temperature data from the Eureka Weather Station.
Today I’m starting what may be a two or three part series having a detailed look inside the Eureka Weather Station and the data it produces. Thanks to the manager of the station Rai LeCotey, we have a lot of new information that had not previously been available on the web. Mr. LeCotey has been most gracious and forthcoming and I commend his openness, which as we have seen in Climate Science, is a rare quality. Here’s an aerial view of the station.

Ecotretas and I looked at a number of what we identified as errors in data from Eureka, Nunavut, Canada weather station. Some errors are real, such as the January 1st 2007 METAR error (caused by transcription error).
We identified what we thought were errors on July 13th and 14th. The Station Manager Mr. LeCotey says that the July 14th new record high temperature “error” was real (meaning meteorological data, not a transcription error), and a function of wind direction bringing air from the North that has been warmed by terrain. He also says he’s working to get the error on Jan 1 2007 corrected in the record. He’s sent along some photo documentation of the July 14th 2009, event. We’ll get to that in a subsequent post, but first some background on the station itself.
Here’s what the Meteorological Instrument Complex looks like:
