This PR includes changes to aop.py and the introduction of three example yaml files in a new config directory for the calculation of particulate matter in different GEOS systems. MERRA-2 requires a conversion of the sulfate ion to ammonium sulfate while all systems that include nitrate can use ammonium directly. The yaml files also reflect that the available species and optics files have changed over time in GEOS.
