Abstract: Formaldehyde (CH2O) is a tracer of the photochemical activity of the atmosphere. Linked to air quality, CH2O is an ozone (O3) precursor and serves as a proxy for natural and anthropogenic reactive organic emissions. As a product of the photooxidation of methane (CH4) and other hydrocarbons (e.g., isoprene), CH2O represents an important source of radicals in the remote free troposphere. This work aims at improving the characterization of this part of the troposphere where data are scarce. In particular, this study assesses the presence of CH2O at two high-altitude remote sites: El Teide (TEI, 3570 m a.s.l., Tenerife, Canary Islands, Spain) and Pic du Midi (PDM, 2877 m a.s.l., French Pyrenees).
Sponsorship : The TEI campaign was funded through the AMISOC project (Atmospheric MInor Species relevant to the Ozone Chemistry, Spanish National RCD Funding Agency, CGL2011-24891). The PDM campaign was funded by the European Research Council Executive Agency under the European Union's Horizon 2020 Research and innovation program (ERC-2010-STG 258537) to JES. LGM would like to the MINECO support under grant VHODCA (CTM2017–83199P).
