Small HONO emissions from snow surfaces at Browning Pass, Antarctica
International audience Measured Fluxes of nitrous acid at Browning Pass, Antarctica were very low, despite conditions that are generally understood as favorable for HONO emissions, including: acidic snow surfaces, an abundance of NO 3 - anions in the snow surface, and abundant UV light for NO 3 - ph...
