MEGANv2.1-ECMWF Methanol emission inventory 2000-2013

Based on the MEGANv2.1 emission model, the MOHYCAN canopy environment model, ERA-Interim fields between 2000 and 2013 and leaf area index from collection 5 8-day MODIS composite from Aqua and Terra, we have built a global inventory of methanol emissions from vegetation at a resolution of 0.5° (Stavrakou et al., 2010).

The monthly averaged emissions (in mg methanol /m2 /hr) are available in NetCDF format:

720 longitudes from 0.25 to 359.75° W, 360 latitudes from 89.75° N to 89.75° S, 12 months
