Load Data and Location

When I run the "Download Electric Load" macro, why does it show a different weather file used to generate the load data than the one I have selected on the Location and Resource input page?
The macro downloads load data from a database of load profiles for 1,020 in the United States -- it does not generate load data on the fly, but intead downloads pre-exisiting load profiles from the database. NREL generated those profiles using the weather files in the TMY3 collection from the National Solar Radiation Database, and the macro shows you which file was used to generate the profile it downloads.
The macro uses the latitude and longitude from the Location and Resource input page to find the TMY3 location (from the list of 1,020 locations) that is nearest the location of the system you are modeling so that the weather data used to generate the load profile is reasonably similar to the weather data you use for your simulation. 
Best regards,
