<p>It's just occurred to me that you were asking for the periods of
record for the NEW CWEC, whereas I thought you were asking about
the earlier CWEC2! <br>
</p>
<p>I haven't looked at the new CWEC, but the epw format should also
so the years for each historical month. Having said that, looking
at the years on the files does not give you an accurate reading of
the period of record.</p>

<p class="MsoNormal"><span lang="FR-CA"><o:p> </o:p></span></p>
<p class="MsoNormal">The government of Canada seems to have
updated their engineering climate data sets to be used for
energy simulations. The new data sets can be found here:<o:p></o:p></p>

<p class="MsoNormal">I quickly compared a CWEC file available
from the doe2 website with the latest CWEC_V_2016 file from
the website above for the same city and sure enough the number
of heating degree days have been reduced and cooling degree
days have gone up. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The issue I have with these files is I
can’t seem to determine what years they are based on. The text
files available on their ftp site are outdated (they maintain
the CWEC files are based on data from 1960-1989), and the
descriptions on the website are ambiguous. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Given the recent flurry of activity on
