TOFP: Tropospheric Ozone Forming Potentials Gap filling codes and procedures: 1 Emission value considered to equal the first (or last) reported emission value. 2 Emission value interpolated 3 Value for sector '1A1a power production' gap-filled using ratio of the ‘1A1a’ sector to the parent sector ‘Energy Industries’ in the most recent year in which both values for both sectors were available. 4 Value for sector '1A1a power production' interpolated using ratio of the ‘1A1a’ sector to the parent sector ‘Energy Industries’ in the most recent years in which both values for both sectors were available. 5 values in 2005 not reported. Values for sector '1A1a power production' gap-filled using ratio of the ‘1A1a’ sector to the parent sector ‘Energy Industries’ using ratio from last year's reported data (2004) 6 Data from RAINS PM10 model (not relevant for greenhouse gases)
