Last year I set up temperature sensors, 1m above ground, 5cm above ground and just below the ground surface at one site near camp at Lake Hazen and logged the hourly temperature for the whole summer. The results are really quite interesting.

at ground level at Lake Hazen in 2014
|Temperatures at Lake Hazen in 2014 were much warmer |
close to the ground and during the "day"
even though there is 24 hours of daylight.

I had temperature sensors set up at both Iqaluit and Lake Hazen last year and one thing I have found through my analysis is that during the middle of the growing season, July, the average temperature at 5cm above ground at Lake Hazen is pretty much the same as at Iqaluit even though the two locations are over 18° of latitude apart. However, the temperatures at Iqaluit tend to get much warmer during the day and dip lower at night than at Lake Hazen.

Lake Hazen sites (dotted lines) and Iqaluit sites (solid lines).
The average temperatures are the similar at Lake Hazen and Iqaluit
but Iqaluit temperatures very more during over a 24 hour period
