Hood was frosty

98% of the surrounding area was -4 to -5 yet the temp will be recorded as much higher in the micro climate of the city limits ... you have it assed backwards

micro climates do not just happen within city limits. My farmyard always is 1-2 degrees colder than the neighbors on either side. I will have frost when neither do. Ever drive past a valley and see fog in it but nowhere else? You been to lakes, have you noted evening and morning freezes near a lakeshore do to the temperture difference between water and ground? Your own farm yard will likely differ from your fields, especially if there are shelterbelts, building etc. So what if it was warmer in the city if it is consistantly warmer in the city. The only backward one is the person who thinks microclimates are strictly an urban phenomena

Drive a quadrunner down a road on a calm eaving, probably 5 degree temperature change in a hundred yards.

In a field just doesn’t cut it for accuracy to me.

Worked black will be totally different than stubble. I’m not sure where would be best but to me ground level readings have way to many variables.

My guess would be that air temperatures would have to be monitored above ground at some level that has allowed the air to mix enough to be more stable. The higher atmospheric levels would be more accurate, no?

Temps are taken a precise distance off the ground. Grass covered ground is best. No trees within an equivalent of their height. At least these were environment Canada regulations when we had our station.

Want to send a big thank you to all of the contributors to this great thread. What a relief it is to be back to arguing about the (relatively speaking) unifying topic of global warming and weather instead of covid, just like the good old days.
Anyone want to start a thread about bringing back the CWB or alternative energies now?

Oil is higher in canola around home which is within reach of the wind turbines. Obviously they help keep things cooler and therefore canola didn’t have such heat stress and the oil is higher.

Yay for wind turbines!

Has to be true, after all, this has turned into a global warming thread, and the global warming proponents insist that correlation always implies causation. Except when it is inconvenient.

Agree but you are missing the point completely, or simply ignoring it . Absolutely temps are different in many areas on calm nights / mornings . That h

Why it important? Temps used it artificially warm areas like urban micro climates are being used as a basses for global warming. As never changed in thousands of years .
Was simply pointing out that fact . Taking temps from areas that represent a fraction of the area . Whats the big panic , 2c and the world will end from the climate cult ?
Easy to cherry pick data that does not represent 98% of the land mass around it .

It all ends up skewing the average temps , and by 1.5c ..... obviously not hard to do .

It would be manipulation if they continually moved weather stations but if they use the same station in the same location year after year for decades it will reflect if change is happening. Just because it disagrees with your micro climate temps is irrelevant. Likely would
get same rate of change if your station was used long term

Except if that same location becomes encircled by pavement, city heat and airplane exhaust. Then it is not in the ‘same’ location.
