Greetings! Apologies on the delayed response. CAPE is implemented as a direct integral over the environmental temperature profile and the calculated parcel profile. Any error margin in the calculated CAPE value is really the error margins from the original data, scaled by metpy.constants.Rd since that's what converts the integrated temperature difference to energy. Hope this helps, Ryan > Hi Ryan, > > I'm currently writing a paper on severe convective storms over Europe using > your MetPy code for surface-based CAPE.
