  1. *Model levels can be converted to pressure levels p with the following equation pi = psfcBi + Ai [in Pa] where psfc is surface pressure and Ai and Bi are static coefficients defined for each model level i (https://confluence.ecmwf.int/display/UDOC/L137 + model + level + definitions). The volume of atmospheric-tracer parameters has been highlighted in bold. The individual parameters are listed in Supplementary Information file 1 (Table S1).
