Developing Releases Bugfixes

This page contains a listing of all the bugfixes required for the Developing releases.

Fast-JX dm_3d bug

The calculation of mass in ukca_fastjx.F90 is incorrect. This will affect low-top models more, but will also affect high-top models.

The line

     dm_3d(:,:,(model_levels+1))     = pz_3d(:,:,model_levels+1)/g 

should be replaced with

     dm_3d(:,:,(model_levels+1))     = pz_3d(:,:,model_levels)/g 

Please include the following branch in the PUMA UMUI
