| Popis: | International audience; The photolysis of HONO has been found to be the oxidation driver through OH formationin the indoor air measurement campaign SURFin, an extensive campaign carriedout in July 2012 in a classroom in Marseille. In this study, the INCA-Indoormodelis used to evaluate different HONO formation mechanisms that have been used previouslyin indoor air quality models. In order to avoid biases in the results due to theuncertainty in rate constants, those parameters were adjusted to fit one representativeday of the SURFin campaign. Then, the mechanisms have been tested with theoptimized parameters against other experiments carried out during the SURFin campaign.Based on the observations and these findings, we propose a new mechanismincorporating sorption of NO2 onto surfaces with possible saturation of these surfaces.This mechanism is able to better reproduce the experimental profiles over alarge range of conditions. |
