BGCv3p0

Control simulation.

A new version of the biogeochemical model (B3p0, manual here) has been used with the SOURCE Catchment 2014 vegetation cover. An assessment of the this hindcast against observations (and the previous version (B2p0) is available here: gbr4_H2p0_B3p0_Chyd_Dcrt_4April19 .

Results of the data assimilation simulation.

The data assimilation system uses the mismatch between modelled and observed OC3V (VIIRS 3 band ocean colour algorithm) to update the number of phytoplankton, which then changes the calculated OC3M. The figure below shows the OC3V of the non-assimilating (B3p0) and the ensemble mean of the assimilating (reanalysis) simulations for different regions along the coast.
