Hello,
Here is really a great application that will allow in the blink of an eye to assess the air masses to come.

I have a question about its use. Maybe a silly question...
Weather models "smooth" the real terrain. This means that a real altitude of 1631m is indicated at ~1011m on the emagram (example).
As a result, the Iso-R curve begins its rise from the 1011m level and not 1631m. Also, it doesn't start from the dew point temperature curve as I learned to plot lifts. This means that it quickly crosses the dry adiabatic.

Is there a possibility to artificially modify the altitude of the base of the emagram? Going from 1011m to 1631m?
And make the line following the Iso-R curve start from the dew point temperature curve? Like in the picture below?

I may be using the tool incorrectly...
Thank you for your work and your clarifications.
Mikael
