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. A years average emissions using the interactive scheme are shown below.

The distribution is broadly similar, with the most notable difference being seen in increases in Africa. The emissions model also produces terpene emissions as well. The total emissions for this particular year is 480 Tg of carbon compared to 440 Tg C with the climatological scheme.
