• Emissions files require the 'date' variable, with 'time' dimension (and 'datesec' if you have sub-daily emissions); the model does not use the 'time' variable, but you can include it.
• All 3D (time,lat,lon) variables in the file will be read.  If you have a 'total' or 'sum' in addition to individual sectors, all variables will be read and you will have twice the emissions you expected!
• In 'vertical' emissions, you may include whatever vertical structure you want (1 km, 0.25 km, regular or irregular grid), but both 'altitude' and 'altitude_int' variables must be included.
• The MAM (modal aerosol model) number emissions in the emissions files are in the units of '(particles/cm2/s)(molecules/mole)(g/kg)'.  This is because when emissions are read in CAM they are scaled by Avogadro's number and (1kg/1000g), which is needed for most emissions that are read as (molecules/cm2/s).  More information available at: Aerosols section of this wiki.

Combined emission files

Preprepared emission files with all or some of the required source sectors.
