Short summary

Soil reactive nitrogen (Nr) gas emissions from the Tibetan Plateau remain poorly quantified, especially nitrous acid (HONO) and nitrogen oxides (NO_x). We find soil HONO and NO_x emissions are substantial across different land use types, with annual emissions of 7.0 ± 3.4 and 20.3 ± 7.0 Gg N yr⁻¹, respectively. Soil HONO emissions contribute approximately 10.5 % of the external daytime atmospheric HONO sources and modulate the regional atmospheric chemical balance by elevating the HONO/NO_x ratio.
