Does anyone know where to get specific weather data for a certain time
period. The data could be temp & humidity for December 2008 on a day by
day basis?

www.wunderground.com

historic weather data, usually hourly or better, is available for sites
all over the world, and in csv format.

I've asked if these guys at wunderground could make the csv data
available via ftp, but to no avail. Downloading 365 days of csv from the
website page-by-page is a pain.
If anybody else has any luck, please let me know.
The other option is to webscrape the data with a bot. Far beyond my
expertise - any web coders out there?

We subscribe to NOAA data files - you need to pay per year for each site.

The NOAA / NNDC files are monthly files and are ~1-2 months behind in
compilation (based on my subscription). It's somewhat painful to copy, and
paste individual months into an annual file.

Also, there is no solar data in the file.

Dear users

Mr. Jason Glazer already introduced the EnergyPlus Weather Data site.

(http://apps1.eere.energy.gov/buildings/energyplus/cfm/weather_data.cfm)

You can directly use the EnergyPlus to use a certain weather data.

Or* why don't you use ESP-r* which enables you to inport EnergyPlus Weather
files (*.epw) and generate a csv file from your weather data?

Besides the canned weather data (typical years made from a period of
record) for EnergyPlus, the site also references the real time weather
data:

I've posted an excel spreadsheet that fetches the wunderground data for
a specified location and date range:

The code was written by a coworker of mine; I haven't personally
inspected it.

A couple of months ago I posted a "work-flow" for getting this info into
an eQuest-usable format because I've been having some trouble. Here it
is again, if anyone could provide guidance as to why this flow isn't
working. And, if anyone knows if this is still applicable for eQuest
v.3.63 I would appreciate that insight as well.
