Boundary Layer Height retrieval from Lidar and Ceilometer data
The height of the planetary boundary layer (PBL) is a key parameter in the description of mixing and transport of air pollutants, greenhouse gases, water vapour and turbulent energy. The PBL height can be determined from groundbas ...

Estimating global GPP from delta^18 O (CO2) observations
Background
The growth rate of atmospheric CO2 is determined by its emissions from fossil fuel combustion and biomass burning and the CO2 uptake by the terrestrial biosphere and oceans. The exchange of CO2 with the biosphere is th ...

First light for TROPOMI
On 13 October 2017, the Dutch satellite instrument TROPOMI will be launched. This instrument will measure air pollution with a very high degree spatial detail (3.5x7 km2). This spatial resolution makes it possible to detect --for ...

Trends in NO2 air pollution
Former President Obama recently showed that satellite measurements of NO2 indicated that concentrations of this air pollutant have decreased by almost 50% over the United States and Europe between 2005-2010. Since 2010 however, va ...

Can NO2 from space be used as a proxy for CO2 emissions?
Monitoring CO2 emissions is increasingly relevant in the context of the Paris Climate agreement. However, there is no system in place to monitor these emissions from space. Satellite instruments detect the short-lived pollutant NO ...

The Amazon Carbon Balance
The Amazon carbon balance will play an important role in climate change, because of its numerous feedbacks. We know relatively little of this area, but new measurements are being gathered on the ground, as well as from the atmosph ...

Impact of urbanization on climatological temperature series
For understanding climate change, the analysis and interpretation of temperature records from routine weather stations is crucial. However, many of these stations have been subject to changes in the long term record (sometimes > 1 ...

Mapping changes in tropospheric O3 from space
Background
Ozone close to the Earth is produced by photochemical reactions in the lower troposphere. It also comes down from the stratosphere and via entrainment mixes into the boundary layer. There are too few ozone measurements ...

Simulating Air Quality with WRF-Chem
Air quality is a hot topic nowadays, in the Netherlands, Europe, Asia and other places. Traffic, industry and power generation cause large emissions, which compete with biogenic emissions from forests, peatlands, agriculture and f ...
