NO
- Anthropogenic emissions: Edgar3.2 for TM5; Van Aardenne or POET for TM4
- Distribution of fossil/industrial emissions over two vertical levels (below and above 100 m) seems different for TM4/TM5: TM5 uses IMAGE regions
- Aircraft emissions: all use ANCAT plus year-dependent scaling factor
- Biomass burning seasonality: Hao et al. ('bmbcycle'); temperate fires distributed over summer months
- Monthly agricultural and natural soil emissions: Yienger and Levy for both TM4 and TM5
- Lightning: calculated when new meteo comes available: same in TM4 and TM5??
- Where are NO emissions actually added in TM5??
NH
- Anthropogenic (incl. biomass burning) and soil/ocean emissions: Van Aardenne for TM4 and TM5
- TM5 has refinement and distribution over months of Van Aardenne emissions ANM and FER (agriculture) using data from Bouwman
SO
- Anthropogenic emissions: IIASI, 2000-BAU for TM5; Van Aardenne for TM4
- Vertical distribution over two levels different for TM4 and TM5
- Biomass burning: Vd Werf for TM5; Van Aardenne for TM4
- Volcanoes: Aerocom (distributed per grid cell between two heights) for TM5; GEIA for TM4
DMS
- Seems the same for TM4 and TM5
- Land emissions: Spiro database
- Ocean emissions: calculated after reading new meteo based on wind speed etc. in combination with seawater concentrations
CO
- As for NO: Edgar vs Van Aardenne
- Fossil and industrial emissions distributed over months ('coseas'), both in TM4 and TM5. Why is this not done for other gases like NO?
- Biofuel/waste/biomass burning: distributed over 4 vertical levels (0-100-500-1000-2000 m) in TM5. This is not done in TM4.
- Biogenic ocean plus vegetation CO: same in TM4 and TM5. Total 115 Tg yr
NMV
- As for NO: Edgar vs Van Aardenne
- Intriguing difference:
- TM4: nmhc_to_c = 0.8 cbm4_represented_fraction
cbm4_represented_fraction = 0.87
- TM5: nmhc_to_c = 0.8
ISOP
- Guenther inventory for both TM4 and TM5
- Difference in global annual total: 453 (TM5) vs 400 (TM4) Tg C yr
- Diurnal distribution implemented in TM5
CH
- Quite different
- TM5 based on Edgar3.2 for anthropogenic emissions.
- TM4 based on Edgar2 (1990) for some anthropogenic sources, Van Aardenne for landfills and biomass burning, Matthews for rice.
- Natural emissions are probably similar.
- Some smaller sources appear to be missing in TM5: coastal, volcanoes, wild animals.
