Long-term monitoring of black carbon across Germany

Julia Schmale

Lately, black carbon (BC) has received significant attention due to its climate-warming properties and adverse health effects. Nevertheless, long-term observations in urban areas are scarce, most likely because BC monitoring is not required by environmenta ...

Design of a spatial data infrastructure for low-cost distributed air quality sensors : a contribution to the Chicago Array of Things project

Anaïs Laurence Ladoy

In the context of this master thesis, a Spatial Data Infrastructure (SDI) was designed to store distributed air quality sensors data to provide a framework to facilitate the downloading, the analysis and in turn the understanding of the spatial distributio ...

Optimal Search Strategies for Pollutant Source Localization

Auke Ijspeert, Howard Li

This paper is aimed at developing optimal motion planning for a single autonomous surface vehicle (ASV) equipped with an on-board pollutant sensor that will maximize the sensor-related information available for source seeking. The ASV uses a nonlinear diff ...
