aircraft.2x25.1992.jan    -- SO2 emissions from aircraft. These are fuel  
aircraft.2x25.1992.feb       burned in [kg/box/day], from AEAP for 1992. SO2  
aircraft.2x25.1992.mar       emission is calculated by assuming an emission 
aircraft.2x25.1992.apr       index EI of 1.0, i.e., 1g of SO2 emitted per kg
aircraft.2x25.1992.may       of fuel burned.  It is also assumed that there is
aircraft.2x25.1992.jun       no diurnal variation of emission rate.
