Chemistry of the Stratosphere and Troposphere


The TropIsop and Stratospheric chemistry schemes have been merged to produce a UKCA configuration suitable for simulating the chemistry of the stratosphere and troposphere (CheST).

The CheST scheme considers emissions of NOx, CO, C2H6, C3H8, C5H8, HCHO, CH3CHO and CH3COCH3 and surface boundary conditions of CH4, CFC's and N2O.
