I believe that in the TMY2 format, columns 2 and 3 of each line contain
the year on which that data point was recorded. I am not sure what is
done for TMY2 files that are "created" instead of containing
recorded data. <br>
Kind regards,<br>

TM2 is only a data format. It depends on what the person who created the
file put into it. Usually, the data are averages over many years. <br>
<br>
The TM2 files delivered with TRNSYS were created with METEONORM <br>
(see
<a href="http://software.cstb.fr/soft/present.asp?context=Meteonorm&langue=us">
http://software.cstb.fr/soft/present.asp?context=Meteonorm&langue=us</a>
)<br>
and do not represent 'real years', but 'Typical Mean Years' (that's where
the names TM2 and TMY come from). <br>
<br>
The TMY2 users manual is available online
