Nitrogen oxides (NO<sub>x</sub>) play key roles in atmospheric chemistry, air pollution, and climate. While the largest fraction of these reactive gases is released by anthropogenic emission sources, a significant amount can be attributed to vegetation fires. In this study, NO<sub>2</sub> from GOME-2 on board EUMETSAT's MetOp-A and OMI on board NASA's Aura as well as fire radiative power (FRP) from the measurements of MODIS on board NASA's Terra and Aqua are used to derive fire emission rates (FERs) of NO<sub>x</sub> for different types of vegetation using a simple statistical approach. Monthly means of tropospheric NO<sub>2</sub> vertical columns (TVC NO<sub>2</sub>) have been analyzed for their temporal correlation with the monthly means of FRP for five consecutive years from 2007 to 2011 on a horizontal 1° × 1° grid. The strongest correlation is found to be largely confined to tropical and subtropical regions, which account for more than 80% of yearly burned area on average globally. In these regions, the seasonal variation of fire intensity, expressed by the FRP data, is similar to the pattern of TVC NO<sub>2</sub>. As chemical models typically require values for the amount of NO<sub>x</sub> being released as a function of time, we have converted the retrieved TVC NO<sub>2</sub> into production rates of NO<sub>x</sub> from fire (<i>P</i><sub>f</sub>) by assuming a constant lifetime of NO<sub>x</sub>. The comparison between <i>P</i><sub>f</sub> and NO<sub>x</sub> emissions from GFEDv3.1 over 5 characteristic biomass burning regions in the tropics and subtropics indicated good agreement. By separating the monthly means of <i>P</i><sub>f</sub> and FRP according to land cover type, FERs of NO<sub>x</sub> could be derived for different biomes. The estimated FERs for the dominating types of vegetation burned are lowest for open shrublands and savannas (0.28–1.03 g NO<sub>x</sub> s<sup>−1</sup> MW<sup>−1</sup>) and highest for croplands and woody savannas (0.82–1.56 g NO<sub>x</sub> s<sup>−1</sup> MW<sup>−1</sup>). This analysis demonstrates clearly that there are biome-specific, diurnal, and regional differences in FERs for the dominating types of vegetation burned in the tropics and subtropics. Possible factors affecting the magnitude of the obtained values are discussed.
