Mc Tavish and Burnside Wind Speed and Direction (Oct 21-22)

I looked at wind speeds and directions from thursday 21st to friday 22nd. The attached graphs show you what I have found out. First of all, I realised that the Burnside data (for whatever reason) is shifted by 4 hours. So the wind data are recorded with a time tb = tt + 4. To correct for this difference I simply subtracted 4 hours in the time columns for burnside. That is why the burnside data actually starts at t = -4. Note that the datasets end at 8pm local time on the 22nd October (that means at t = 44h, 4 hours before midnight).
If we correct for this shift the two data records correlate quite well. However, this is only based on qualitative estimation. As you can see from the Windrose plots, during relatively large time intervals Burnside and McTavish have more or less the same wind direction.
However, I tried some regression analysis and the correlation coefficients for the wind direction is always very low. That mean we don't have a quantitative proof yet to confirm our hypothesis. Maybe we can ask one of the profs to find out how we can use statistics to proof our finding quantitatively.

Weekend CO2 Events

Over the weekend I witnessed a few potential sources of CO2. A building was on fire Friday afternoon and Saturday day and night University street was closed for construction on the sewers.

Friday, on René-Lévesque Blvd. near the intersection with de Lorimier Ave. at 2 p.m. fire crews were on the scene of a two-alarm blaze.

Saturday, morning till night, university street right next to our machine was emmitting this huge cloud of white smoke. I asked the workers what they were doing and they said repairing the sewers. (See pictures posted below, taken at 10pm Saturday night).

Next week I think it would be cool to see if we can detect these events with the use of piccaro and wind speed and directions!

Point Sites on Mt. Royal

I've picked these sites based on accessibility, their elevation and how close they are to a road. All three of them are in a forested area, roughy the same elevation (Location C is higher, but also the most remote).

They can be accessed at any day and usually have people around them so they would be safe at night as well. Check out the Google Map for their exact location.
