Tropospheric a Burden, Lifetime, Deposition, and Emissions Calculated Over Only CONUS for the Different Grids Using TS1
| Calculation (unit) | ∼111 km b | ∼14 km c |
|---|---|---|
| Ozone Burden (Tg) | 6.1 | 6.4 |
| CO Burden (Tg) | 4.4 | 4.7 |
| CH4 Burden (Tg) | 57.4 | 56.5 |
| CH4 Lifetime (yr) | 6.3 | 7.2 |
| Ozone Dry Dep (Tg/yr) | 43.9 | 47.3 |
| HNO3 Dry Dep (Tg/yr) | 4.7 | 4.7 |
| HNO3 Wet Dep (Tg/yr) | 5.2 | 5.9 |
| Lightning NO Emis (Tg N/yr) | 0.2 | 0.4 |
| Isoprene Surface Emis (Tg/yr) | 13.5 | 25.0 |
Note. Dep = deposition; Emis = emissions; CO = carbon monoxide; CH4 = methane; HNO3 = nitric acid.
a
Troposphere defined as region where ozone is less than or equal to 150 ppb.
b
∼111 km horizontal resolution globally (ne30 grid).
c
∼14 km over CONUS and ∼111 km horizontal resolution over the rest of the globe (ne0conus30 × 8 grid).
