Whatever made the file has the day of month for month 2/1 as 32 (which
would be day of year)
It looks like the Ecotect WEATOOL was used? you can use the
EnergyPlus weather converter to convert wea files. There were some
problems I noticed with the WEATool and I uploaded a special ccf to be
used with Ecotect to the Files area.
(I see you have just answered this as well).
By the way, the latest version of Meteonorm makes epw files
directly.
The other option would be to treat this as a custom file needing a
def and use that value as "day of year". And then use the
EnergyPlus weather converter.
