When adding an observed temperature and Td, sounderpy created funky lapse rates for a convective case in the Northern Rockies using ERA5 data. For some reason, sounderPY adds an artifact above the surface where the lapse rate goes straight up before cooling off. This doesn't make sense for a summer day around peak heating in Missoula. It could also be the reason that the 0-3km lapse rate was 11 C/km. Also the surface elevation is incorrect: It seems like this is a problem with the ERA5 data(when looking at the sounding without sfc inputs). It puts KMSO at 850mb which is unrealistic. KMSO is at 3199 feet (975 meters) which according to the OTX sounding at 00z would have been approximately near 925 mb on that particular day (not 850mb!).
Add the capability to add 1-3 data points to the sounding AND the pressure level. There are plenty of mid-slope and mountain-top observations that could help supplement the soundings so that a more realistic low-level lapse rate can be achieved. i.e. Point 6 is at 2407 meters (7897 ft), which looking at the OTX sounding at 00z 7/25, would have been somewhere around 765 mb and it's 4:59pm MDT (~23z) obs were 25 C(T) and 4 C(Td).
