Interactive Biogenic Emissions

We are in the process of implementing interactive biogenic emissions at UM7.3 based upon the code used at UM7.7 in the ExTC branch. Initially we are looking at isoprene emissions, but terpenes emissions will be available as well. In the standard model isoprene emissions are calculated from a climatology (emissions shown below):

The interactive emissions are based upon the scheme of Pacifico et al (2010) as implemented by Gerd Folberth at the Met Office. We have implemented the scheme into a branch taken from the VN7.3 standard branch, with some changes, for instance ensuring that the land sea fraction has been applied. When we run we see emissions that look like

(though note there is a global scaling factor of 2.5 applied here). These will be available in the near future.
