Applying these to the nine model cells with agricultural activities around the Chino area
yields emission fluxes of NH3, DMS, and DMDS of 31, 0.24, and 5.8 × 10 − 3 μmol m − 2 d − 1, respectively.
In Actuality, air sampling surveys over ESAS
yield a calculated annual
flux to the atmosphere of 8 Tg C - CH ₄ (Shakhova et al., 2010), a figure 200 x higher than the model estimate (at Year - 1 of this 100 - kyr - scale warming) and equivalent to the methane
emissions of the entire world's oceans.
