Global Biogenic dataset updated

CAMS biogenic emissions were calculated using MEGANv2.1 (Guenther et al., 2012). MEGAN is a modeling system for estimating the net emission of gases and aerosols from terrestrial ecosystems into the atmosphere. MEGAN is a global model with a base resolution of ~ 1 km and so is suitable for regional and global models. CAMS-BIO data set is based on the ERA-Interim meteorological fields. Land cover distribution is defined by grid cell coverage with 16 plant functional types consistent with the Community Land Model (CLM4). The model calculates with Leaf Area Index (LAI) data processed from the MODIS instrument observations (Yuan et al., 2011). CAMS-BIO data are available as monthly mean emission fluxes as well as monthly averaged daily profiles of emissions.

The CAMS-GLOB-BIO v2.2 version dataset is based on the ERA5 meteorological fields. Isoprene emissions in Europe were calculated with updated emission potential (EP) values. These EP are based on detailed land cover distribution in Europe. For the rest of the world land cover distribution is defined by grid cell coverage with 16 plant functional types consistent with the Community Land Model (CLM4)
