UKCA currently uses two different methods of defining the chemical reactions solved in the model. The first is a backward Euler solver, and is used for the ''RAQ'' and ''StdTrop'' chemistry schemes. The second makes use of the [http://www.atm.ch.cam.ac.uk/acmsu/asad/ ASAD chemical integration software package], and is used for the ''CheT/TropIsop'', ''CheS/Strat'', and ''CheST/StratTrop'' chemistry schemes. ASAD can use many different solvers, although currently it uses symbolic Newton-Raphson solver. |

Adding new Chemical Reactions
UKCA currently uses two different methods of defining the chemical reactions solved in the model. The first is a backward Euler solver, and is used for the RAQ and StdTrop chemistry schemes. The second makes use of the ASAD chemical integration software package, and is used for the CheT/TropIsop, CheS/Strat, and CheST/StratTrop chemistry schemes. ASAD can use many different solvers, although currently it uses symbolic Newton-Raphson solver.
