Polar stratospheric nitric acid depletion surveyed from a decadal dataset of IASI total columns [PDF]
Atmospheric Chemistry and Physics, 2022 In this paper, we exploit the first 10-year data record (2008–2017) of nitric acid (HNO3) total columns measured by the IASI-A/MetOp infrared sounder, characterized by an exceptional daily sampling and a good vertical sensitivity in the lower-to-mid ...

Ethylene industrial emitters seen from space
Nature Communications, 2022 Combining 13 years of satellite measurements led to the discovery of 300 global hotspots of atmospheric ethylene (C2H4). They are found to be linked to heavy industries and megacities, and are currently misrepresented in emission inventories.

Covering Squares with Squares [PDF]
Discrete & Computational Geometry, 2000 The authors consider covering a square \(Q\) by the sequence \(\{Q_n\}\) of squares, where \(Q_n\) has side of length \(x^n\) for \(n=1,2,\dots\).

On the weekly cycle of atmospheric ammonia over European agricultural hotspots
Scientific Reports, 2022 The presence of a weekly cycle in the abundance of an atmospheric constituent is a typical fingerprint for the anthropogenic nature of its emission sources. However, while ammonia is mainly emitted as a consequence of human activities, a weekly cycle has

Trends in spectrally resolved outgoing longwave radiation from 10 years of satellite measurements
npj Climate and Atmospheric Science, 2021 In recent years, the interest has grown in satellite-derived hyperspectral radiance measurements for assessing the individual impact of climate drivers and their cascade of feedbacks on the outgoing longwave radiation (OLR).

Measurement report: Ammonia in Paris derived from ground-based open-path and satellite observations [PDF]
Atmospheric Chemistry and Physics, 2023 Ammonia (NH3) is an important air pollutant which, as a precursor of fine particulate matter, raises public health concerns. This study analyzes 2.5 years of NH3 observations derived from ground-based (miniDOAS; differential optical absorption ...

IEEE Open Journal of Antennas and Propagation, 2023 Mesh division plays an important role in applications of the finite element method (FEM). The proposed research shows that under the same order, the equilateral triangular meshes have the most uniform dispersion distribution. The isosceles triangles with
