Shameful: Environment Canada’s Sunshine Data

Filed under: Canada,Environment Canada Data,Sunshine — sunshinehours1 @ 9:25 AM
Tags: , , ,

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

Filed under: Alberta,Canada,Environment Canada Data,Snowfall — sunshinehours1 @ 12:16 PM

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.

British Columbia Canada Tmax , Tmin and Tmean from 1873 (On 1×1 Grid)

Step 1: Use Data from Environment Canada’s monthly summaries.

Step 2: Summarize the data by 1×1 grid square so no region dominates.

Step 3: Graph Tmax, Tmin and Tmean.

The black line is the monthly data. The blue boxes contain the 5 year mean (and I set the 5 year period by just going back from the most recent data in 5 year increments)

The green line is the number of 1×1 grid squares. The blue dashed line is the trend from 1873 (which is the earliest data).

(I won’t count the pre-1900 data as too important since there were so few stations)

Tmax was 1.5C  warmer in the the 1920s/30s/40s than now.

Tmin now is the hottest its been since 1900.

Tmean in the early 40s was slightly warmer than now.

Tmean/Tmin has been warming since 1970 thanks to Tmin … not Tmax.

If you take Environment Canada’s monthly summaries from 1998 to April 2015.

Use only the station with pre-calculated Normals  (anomalies from 1981-2010 avg).

Average them on a 1×1 grid and then graph the data:

November 2014 – 30% of Canadian Stations Were in the Coldest 5 Tmin

Filed under: Canada,Environment Canada Data,Temperature — sunshinehours1 @ 9:48 AM
Tags: , ,

Using November Tmin data from Environment Canada’s monthly summaries.

I used the following filter. There had to be 25 years of data. And there had to be data in 2014.

420 stations fit that criteria.

For 122 of those stations, November 2014 was in the top 5 coldest.

So, for example. 108 MILE HOUSE ABEL LAKE has 27 rows of data, and 2014 is ranked as the 4th coldest.
