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
About the data
Based on the MEGANv2.1 emission model, the MOHYCAN canopy environment model, ERA-Interim fields between 2000 and 2012 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°. The dataset is described in full detail in Stavrakou et al., (2011).
Additional information
