Ivo, can you add a Thermal Base button for the Soaring and Gliding communities?

Super easy to calculate if you wish to go simple.
Thermal Base = 1,000 ft per 4.4F° difference in surfacetemp - dewpoint
(there are more complex formulas but this is good enough, this usually also forecasts the cumulus layer cloud base).

Thank you for a most awesome site! - Michael Price

Any chance there could be a 1000 ft AGL option? That would sure be useful for us sailplane pilots going ridge soaring (big gap between 330 ft and 2000 ft). Thank you for the consideration and awesome site!
