			==== Dennis Roof Data ====
			* Data was retrieved from the weather station on the roof of Dennis
			* Data ranges from January 5th 2000 to March 10 2009
			* The average wind speed over that time is 5.64 M/s
			* Assuming the sensor is at 10 M the 1/7th power rule extrapolates that the wind speed at 100M should be 7.84 M/s

			* Prior to processing all values about 30 M/s were removed
			** Removal was justified by the range of values (up to 8008 M/s) that failed sanity check
			** Removal does not affect power generated as there wind speeds above 25 M/s are not usable by the wind turbines.
			** Prior to removal of 300 M/s+ data sensors three and four had roughly similar average values
			* RP&L data shows a significantly higher windspeed than is estimated by satellite data (6.5 M/s)
			** This increased the estimated output by turbine by roughly one third.
