[MAX-DOAS Tomography Reconstruction for Gas Plume].
Guang pu xue yu guang pu fen xi = Guang pu, 2015In order to achieve precisely two-dimensional spatial distribution reconstruction of smoke plume, passive MAX-DOAS tomography is established, the measurement of the spatial distribution of the exhaust plume is implemented by more passive multi-axis differential absorption spectrum system.

Reconstruction of NO2 spatial distributions basing on scaning MAX- DOAS tomography
Light, Energy and the Environment, 2016A method was developed to reconstruct spatial distributions of NO2 emission of industrial chimneys basing on timing scanning MAX-DOAS system, combining computed tomography. Visual spatial distribution of NO2 concentrations was formed.

Detecting lightning NOx from ship-borne MAX DOAS measurements
Transit cruises of German research vessels across the great oceans provide a unique platform for Multi AXis Differential Optical Absorption Spectroscopy (MAX-DOAS) measurements of atmospheric trace gases such as nitrogen dioxide (NO2), formaldehyde (HCHO) and sulphur dioxide (SO2) in pristine locations. Here, we present results of the Extra AtmosphericSteffen Ziegler +6 more

Ground-based MAX-DOAS observations of formaldehyde and glyoxal in Xishuangbanna, China
Journal of Environmental SciencesMulti-axial differential optical absorption spectroscopy (MAX-DOAS) measurements were conducted in Xishuangbanna, Yunnan, China, between November 1, 2021 and June 30, 2022 to obtain vertical distributions of formaldehyde (HCHO) and glyoxal (CHOCHO). The observations show an increase in vertical column densities (VCDs) and volume mixing ratios (VMRs ...

MAX-DOAS observations of spatial variability of NO2 in Athens
Nitrogen dioxide is a key pollutant in the troposphere. Most of its sources are anthropogenic and linked to the burning of fossil fuels, but wildfires, lightning and soil emissions also contribute to the overall NOx (NO + NO2) loading.Using passive remote sensing in the UV and visible spectral range, NO2 columns can be retrieved with both ground-based ...Andreas Richter +6 more

MAX-DOAS aerosol corrected tropospheric vertical columns of nitrogen dioxide
2009Nitrogen Dioxide (NO2) is an important component of air pollution. It is observed on a global scale by satellite instruments such as GOME, SCIAMACHY and OMI. Worldwide there are only few observation sites where nitrogen dioxide tropospheric columns are monitored on an operational basis.

[Comparison of NO2 slant columns between two ground-based MAX-DOAS].
Guang pu xue yu guang pu fen xi = Guang pu, 2015The study of comparison of NO2 SCD between two ground-based multi axis DOAS is introduced. The slant columns of NO2 from JAMASTEC are compared with those of AIOFM during the period from November to 31 December 2009. It says that the more signal to noise ratio is obtained by using the adjusted integral time rather than fixed settings; Two instrument ...
