TLDR
In this article, the authors measured the NO2 absorption cross-section from 42 000 to 10 000 cm−1 (238-1000 nm) with a Fourier transform spectrometer (at the resolution of 2 cm− 1, 0.01 nm at 240 nm to 0.2 nm at 1000 nm).Abstract:
The NO2 absorption cross-section has been measured from 42 000 to 10 000 cm−1 (238–1000 nm) with a Fourier transform spectrometer (at the resolution of 2 cm−1, 0.01 nm at 240 nm to 0.2 nm at 1000 nm) and a 5 m temperature controlled multiple reflection cell. The uncertainty on the cross-section is estimated to be less than 3% below 40 000 cm−1 (λ > 250 nm) at 294 K, 3% below 30 000 cm−1 (λ > 333 nm) at 220 K, but reaches 10% for higher wavenumbers. Temperature and pressure effects have been observed. Comparison with data from the literature generally shows a good agreement for wavenumbers between 37 500 and 20 000 cm−1 (267–500 nm). Outside these limits, the difference can reach several percent.read more

TL;DR: The HITRAN compilation consists of several components useful for radiative transfer calculation codes: high-resolution spectroscopic parameters of molecules in the gas phase, absorption cross-sections for molecules with very dense spectral features, aerosol refractive indices, ultraviolet line-by-line parameters and absorptionCross-sections, and associated database management software.

Measurements of molecular absorption spectra with the SCIAMACHY pre-flight model: instrument characterization and reference data for atmospheric remote-sensing in the 230–2380 nm region

TL;DR: In this paper, the authors used the scanning imaging absorption spectrometer for atmospheric chartography (SCIAMACHY) pre-flight model satellite spectrometers to measure the gas-phase absorption spectra of the most important atmospheric trace gases (O3, NO2, SO2, O2, H2O, CO, CO2, CH4, and N2O) in the 230-2380 nm range at medium spectral resolution and at several temperatures between 203 and 293

TL;DR: In this paper, an algorithm for the near-real time retrieval of tropospheric NO2 columns from the Ozone Monitoring Instrument (OMI) is presented. But the method is based on the combined retrieval-assimilation-modeling approach developed at KNMI for off-line NO2 from the GOME and SCIAMACHY satellite instruments.

TL;DR: In this article, a comprehensive literature review and comprising input by both satellite experts and emission inventory specialists, the review identifies several targets that seem promising: large point sources of NOx and SO2, species that are difficult to measure by other means (NH3 and CH4, for example), area sources that cannot easily be quantified by traditional bottom-up methods (such as unconventional oil and gas extraction, shipping, biomass burning, and biogenic sources), and the temporal variation of emissions (seasonal, diurnal, episodic).

TL;DR: In this article, it is shown that the conversion of NO to NO2 can be of significance in the interpretation of measurements made near twilight and that multiple scattering from the atmosphere or by clouds is likely to be a very small effect.
