hi, the manual on eQuest only talks about TMY, TMY2 and TMY3 and how they are usually 30 year data of weather to make each TMY.

Question 1:

The CTMY and CTMY 2 (link below):

There's no manual or  information on how  such data sets are obtained does anyone know?

Question 2:

if i click on info for CTMY this is all that it tells you... does it mean thats 30 years worth of data up to 1999? or just 1999 data set

Question 3:

for CTMY2 if i check the info... the same thing...

ABBOTSFO    - 1981

CALGARY - 1961

same question as 2... are these CTMY2 data sets for ONLY those indicated years or are they 30 years upto those years or from those years?

any clarifications or insights would be greatly appreciated

THANKYOU!
