Get Your Environmental Data From the Internet 

SEARCH THE INTERNET FOR CURRENT WEATHER & ATMOSPHERIC DATA

The Internet Weather Assistant Screen is easy to understand and use.   As can be seen in the screenshot above, Intellicast bunches most of the data you need together in an easy to read spot.  Weather Underground provides local weather data and 'Elevation' or Altitude data also.

When you enter data into the fields at the top of this screen, the simulator instantly computes the changes and displays the results.
