We know the lapse rate is 1.98C/1000ft, right?
Set the altimeter to field elevation and read the window to get pressure. It is close enough.
Have someone spawn with an aircraft that has an OAT gauge and read the temp at that field elevation.
You have the data required to convert the performance for that map.
