Notes on accuracy and how some data was calculated
Notes on accuracy:
How some of the data was calculated:
(I added this section to avoid confusion, because the method I use to calculate the monthly and yearly averages is different from Environment Canada)
- Snow depth measurements are taken in my backyard. As a result, they cannot compare to the measurements that would normally be taken in fields (such as at the airport... etc). However, my measurements are therefore more representative of snow depth in urban developments.
- I have found that my thermometer is too warm during cold snaps in the winter... As a result, during these cold snaps I compare with other nearby stations and quality correct the data when necessary. This problem does not occur in the warmer months.
How some of the data was calculated:
(I added this section to avoid confusion, because the method I use to calculate the monthly and yearly averages is different from Environment Canada)
- In the yearly summaries pages, the average high, low and mean temperature for the year as well as the average snow depth and max snow depth for the year are calculated by averaging every single daily value instead of averaging the monthly averages. This is to eliminate the error created by averaging the monthly averages, which are already rounded values. Click here for a more visual explanation.
- It is the similar story for the average monthly mean temperatures. I calculate them by averaging all the daily highs and lows instead of averaging the daily mean temperatures, which are already rounded values. Click here for a more visual explanation.
