In the file: ar5_mam3_POM_surf_1850-2005_c100429_zero.nc
all SOA POM emission fields were set to zero. Later found that the emissions from anthropogenic activity - Bigalk, Bigene and Toluene - should not be zero. 

Created the file: ar5_mam3_POM_surf_1850-2005_c100429_zeroTerpIsopr.nc
where only isoprene and terpene are set to zero. 

For now only have monoterpene and isoprene emission data for present day. When used for preindustrial runs the date had to be changed in these files. bvocgcmFV19_isopr_presentday_w1850date.nc and bvocgcmFV19_monoterp_presentday_w1850date.nc have present day emissions, but are dated to 1850.
