In PATMO internal common variables are accessible. We decided not to use any prefix patmo_, and sure we will regret this, since they might conflict with variable names in your framework code. Only species names have a prefix.

Note that these variables are all parameters.

• reactionsNumber: number of all the reactions (gas chemistry + photochemistry + reverse)

• chemReactionsNumber: number of the gas reactions (no reverse, no photochemistry)

• photoReactionsNumber: number of the photochemistry reactions (no gas chemistry, no reverse)

• reverseReactionsNumber: number of the reverse reactions (no gas chemistry, no photochemistry)

• chemSpeciesNumber: number of gas chemistry species (no Tgas, no dummy)

• speciesNumber: number of all species (including Tgas and dummy)

• positionTgas: position of Tgas in the variable array

• positionDummy: position of dummy in the variable array

• cellsNumber: number of atmosphere layers

• photoBinsNumber: number of photobins

• patmo_idx_[species]: position of a given [species], e.g. CH4 is patmo_idx_CH4.

• chemReactionsOffset: offset in the array of the reactions, i.e. where gas chemistry reactions begin, chemReactionsOffset+1 is the first gas chemistry reaction

• photoReactionsOffset: offset in the array of the reactions, i.e. where photochemistry reactions begin, photoReactionsOffset+1 is the first photochemical reaction

• reverseReactionsOffset: offset in the array of the reactions, i.e. where reverse reactions begin, reverseReactionsOffset+1 is the first reverse reaction

• neqAll: number of all the differential equations, i.e. speciesNumber*cellsNumber

• maxNameLength: maximum number of a string for the species names (not useful for you)

• indexReactants*: an array containing the indexes of the reactants with position , i.e. indexReactants2* is the second reactant.

• indexProducts*: same as above, but for products.
