Alberta Average July Tmax By Decade

I posted some data about temperatures in Edmonton and Alberta. I wanted to visualize it. So I’ve made a grid.

The source of the data is Environment Canadas monthly summaries.

I’m using Tmax, not Tmean. (The logic being that max temps are the problem)

And I’m starting with the July only average for the decade. (I’ll expand in later posts).

There are 1087 stations with July data in Alberta.

I’m narrowing it down to stations with 25 years of data and data all the way up to 2017 and 80% complate.

Things to note:

Only 29 stations make the cut. Only 1 station has the 2010s as the decade with the hottest July average Tmax.

Only 2 stations have data from the 1940s (none before that).

So … AGW ain’t going to kill Albertans in July. They already survived July in the 2000s.

And there isn’t any stations with old and new data. (By that I mean the 30s).

Canada No Longer Publishes Sunshine Data

This annoys me so I bring it up every once in a while.

Could global warming be caused because of more sunshine? In Canada, we’ll never know. The stopped collecting that data in 2015.

Here are three graphs. One shows the number of weather stations (half of what there used to be) and one shows the number collecting sunshine data. A 3rd graph shows what you can do with UK sunshine data.

Shameful: Environment Canada’s Sunshine Data

Once up a time (June of 1978 to be precise)  if you downloaded Environment Canada’s monthly summaries, you would have found 313 stations with “Bright Sunshine” hours.

Even two years ago, these stations were reporting sunshine data:

TORONTO LESTER B. PEARSON INT’L A
CARTWRIGHT
GOOSE A
VICTORIA INT’L A
COMOX A
VANCOUVER INT’L A
WIARTON A

As of today, only WIARTON A reports sunshine data and for May 2015 25 out of 31 days had no valid measurements.

British Columbia Canada Tmax – Missing Data April 2015

This a followup to this post: British Columbia Canada Tmax , Tmin and Tmean from 1873 (On 1×1 Grid)

The following map shows which stations were missing (or not missing) daily Tmax data in the monthly summary for April 2015.

Blue had 0-3 days missing. Red more than 3. What saddens me is that 19 out of the 43 “red” stations were also “Normals” – which means they were reference stations.

Alberta Canada Tmax , Tmin and Tmean from 1873 (On 1×1 Grid) – It Was 2C Warmer in the 1940s

This is the Alberta followup the BC post. You can read the explnations.

In the terms of Tmax the coldest period in Alberta (using 5 year means) was 1972-1976.

The warmest period was 1940 – 1944. In fact it was 2C warmer in 1940-1944 than 2011 – 2015. (The 1930s were just slightly cooler than the early 40s)

You may ask why the green line of grid counts goes up and down so much. It appears there are many more stations reporting in May/Jun/Jul/Aug/Sep than in the winter.
