Table 3.

PM2.5 emissions reported in metric tons for the Hanoi Capital Region (HCR) and Vietnam based on the different rice residue burning scenarios. Residue amounts are in terragrams. Note the emissions estimates are shown to 2 significant digits. Error rates are shown in parentheses for the emission estimates. The last column shows the total percentage of rice residue burning emissions.
