Geographic description: The ambient data are indicated by the location where they collected (e.g. Amazon). The exact locations are: "Gbg" = Gothenburg city’s port, Sweden. "Jülich" = Forschungszentrum Jülich (FZJ), Germany. "Changping" = 40km north-east of downtown Beijing, China close to Changping town. "HK" = Hok Tsui Tsuen area, south-east on the Hong Kong island, China. "Amazon" = Central Amazonia, at a site located 60 km northwest of Manaus, Brazil (0.235680° S, 60.12560° W, 110 m above sea level) facing a huge area (1600 km2) of nearly pristine forest to the east.

If you have published anything based on these data, please notify us with a reference to your publication(s). If you are responsible for the catalogue entry, you can update the metadata/data description in DORIS.
This dataset is based on oxidation experiments of isoprene + NO3 radicals at the atmospheric chamber SAPHIR, in Jülich, Germany and ambient data from five different locations. More specifically, this dataset is provided in order for users to be able to replicate the results from the Tsiligiannis et al. publication. It includes time-series of gaseous species.
The files called I-CIMS contain compounds that measured using a chemical ionization mass spectrometer (CIMS) with iodide as the reagent io
The files called I-CIMS contain compounds that measured using a chemical ionization mass spectrometer (CIMS) with iodide as the reagent ion. The files called Br-CIMS contain compounds that measured using a chemical ionization mass spectrometer (CIMS) with bromide as the reagent ion. The files called TD-CRDS contain the total alkyl nitrates measured using a thermal dissociation−cavity ring-down spectrometer.
The chamber data are indicated by the date of the experiment (e.g. 9Aug). The ambient data are indicated by the location where they collected (e.g. Amazon).
All the date & time data corresponds to local time. For each column, the naming e.g. "BrC4H7NO5_ncps" or "C4H7INO5_ppt", corresponds to the chemical formula of the compound (C4H7NO5) clustering with either bromide or iodide, and the measurement units (ncps=normalized counts per second) or (ppt=parts per trillion by volume). File delimiter is the tabstop.
