7.5 Chemistry

The following schemes are or should be implemented:
project by description
cbm4 Maarten Krol et al. full tropospheric chemistry
eud Maarten Krol ???
strat Jason Williams stratospheric chemistry
co2 Wouter Peters CO2, SF6, 222Rn
ozone Jos de Laat ozone tracer
ch4 (you) methane chemistry
test Maarten Krol hobby project
ipcc JRC cbm4 extended with aerosols, similar to aero
ipcc/m7 JRC M7 aerosol scheme, extension to ipcc
aero Maarten Krol, Arjo Segers cbm4 extended with aerosols, similar to ipcc

A preprocessor generating chemical schemes is under development. First version by Sander Houweling has ported to TM4 by Bruno Guillaume.

7.5.1 Tracers
