Abstract

High HONO level during daytime was observed at a rural site Xinken in southeastern China during the 2004 Program of Regional Integrated Experiments of Air Quality over Pear River Delta (PRIDE‐PRD). The high HONO concentration led to a daytime (9:00–15:00) OH formation up to three times faster than that from O 3 photolysis. An unexplained daytime HONO source, approximately four times faster than the reaction of OH with NO, has been derived from the HONO budget estimation. According to current understanding, this unknown source was attributed to heterogeneous reactions of NO 2 on ground and aerosol surfaces. The good correlation between the unknown source and J values is consistent with the photolytic HONO source observed in laboratory studies.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
