interesting data on inter-year variability of wind: the last 15 years in Germany:

From Spiegel which has more wind-related statistics.

Notice how the variability decreases after the first few years.  Could that be because the interpretation of the statistics got better, even as measurement technology improved?  Could it be that the resource was systematically overestimated in the early stages, as it is in every market?

Tune in next week for a post from my chief, who wrote the book on German wind statistics.  (well, probably not.)

By the way, there is a very cool wind measurement device available for the iphone, taking background sound levels on the mic.  accuracy somewhat included, but it is very cool.

this is meant to be meteorological data, not production data. It should be provided under constant methodology (ie, I presume, average of a large number of anemometers that have not moved).

I don't see any trend in the data, which is as it should be.

Got it, know the data, i'm talking about met data.  better interpretation and more data points, with better anemometer calibration led to more accuracy.  allowed for better corelation to the long term, and the so-called 100% long term average each year's compared to.
