Estimation of Surface NO2 Concentrations over Germany from TROPOMI Satellite Observations Using a Machine Learning Method
TL;DR: In this paper, a machine learning approach is used to estimate surface NO2 concentrations over Germany using satellite data and several meteorological parameters, which is validated against ground-based in situ air quality monitoring network measurements and regional chemical transport model (CTM) simulations.

TL;DR: In this paper, an improved tropospheric NO2 retrieval algorithm from TROPOMI measurements over Europe is presented, where the stratospheric estimation is implemented using the STRatospheric Estimation Algorithm from Mainz (STREAM), which was developed as a verification algorithm for tropOMI and does not require chemistry transport model data as input.
Proceedings ArticleDOI
Air quality monitoring and simulation on urban scale over Munich
TL;DR: In this paper, a downscaling approach is utilized for emission data in order to improve the air pollutants concentration simulation over Munich city using the POLYPHEMUS/DLR chemistry-transport model (CTM).
Journal ArticleDOI
Detecting Moving Trucks on Roads Using Sentinel-2 Data
TL;DR: In this article, a new satellite remote sensing method for detecting moving trucks on roads using Sentinel-2 data is presented, which exploits a temporal sensing offset of the Sentinel 2 multispectral instrument, causing spatially and spectrally distorted signatures of moving objects.
