Re: [EnergyPlus_Support] RH > 100% weather files
You can send the data to me, Joe -- I can't guarantee if the
team will accept it or post it on their website after
processing.

As the original developer of
these weather files, I went back to the original files that are not in
the epw format, and found the reason and cause for these anomalies.
What's reported in the raw data files are the dry bulb and dew point
temperatures, and if they were missing I would interpolate from the
available data.Â
At that time when I created these files (2004), I failed to compare the
dry-bulb and dewpoint to each other to make sure that the latter
(dewpoint) never exceeded the dry-bulb, something that I had added to my
software since.
The correction is very simple, and I have done that on the original
files, but I'm not sure the best way to transmit that to the EnergyPlus
Weather web site. I would be happy to work with Linda to make sure
these changes are added to the "ETMY" weather files.

Hi ,
I hope you are all well and in best conditions.
I have a problem that appeared before in the Alexandria city weather file
and was corrected by Linda Lawrie (great thanks to her). The problem is
that the weather file had times where the outdoor RH values were greater
than 100% which is impossible.
The same problem appears in weather files of the following weather files
in Egypt found on EP website:
Cairo Inl Airport
Al Minya
Asyut
El Arish
Helwan
Ismailia
Luxor
Please help
Thanks
