Simultaneous measurement of atmospheric CH2O, O3, and NO2 by differential optical absorption
Abstract
Formaldehyde mixing ratios are reported for rural areas around Jülich and for maritime air at the north coast of Germany. The measurements were made using a ground‐based UV‐optical absorption technique which allowed the simultaneous determination of CH 2 O, NO 2, and O 3 with detection limits of 0.1, 0.1, and 1 ppb, respectively. In Jülich, which may be regarded as typical for central European background atmosphere, mixing ratios varied from 0.1 to 6.5 ppb from May through October 1978. In maritime air under conditions when photochemical equilibrium was expected, formaldehyde concentrations of 0.2 ppb were observed, which can be accounted for by photochemical oxidation of methane alone. However, the high concentrations of formaldehyde found at Jülich indicate other sources of formaldehyde.

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.
