[BLDG-SIM] Weather Data -- Joint Frequency Distribution Plots Superimposed on a Psychrometric Chart

Joint frequency tables for DB/WB, DB/DP, DB/enthalpy, and DB/WS are
available on the ASHRAE Weather Data Viewer (WDVIEW) CD-ROM product. The
cumulative frequencies and joint frequencies of these parameters are given
by month or for the entire year for each of the 1400+ locations that are
listed in the ASHRAE Handbook - Fundamentals. A description of the CD can be
found on the ASHRAE TC4.2 website or at
http://www.bae.uky.edu/~colliver/Programs/wdview_21.htm
The joint frequency data presented in the CD will then have to be imported
into a program than can plot the 3-D data. I used Excel but other packages
may be used.
Hope this helps.

Superimposed on a Psychrometric Chart
Dear Building Simulation List,
I think that I've seen joint frequency binned weather data (drybulb,
wetbulb) plotted on a psychrometric chart. Colors may have been used to
indicate the number of hours in each bin.
It may well have been a custom application, but if there is a commercial
product that does this, I would be interested in knowing who to contact.
Thank you,
Tom Davidson
