We report an open-path and anti-pollution multi-pass cell based tunable diode laser
absorption spectroscopy (TDLAS) sensor, which was designed for online measurement of …

We develop a new technique called plume regression where fast response instruments
located at the roadside are used to measure exhaust plumes of passing vehicles. The …

Dry deposition of ammonia (NH 3) is the largest contributor to the nitrogen deposition from
the atmosphere to soil and vegetation in the Netherlands, causing eutrophication and loss of …

In this study we present and analyze a two-year dataset of NH 3 exchange over a temperate
Douglas fir forest in the Netherlands. The atmospheric NH 3 concentration ([NH 3]) was …

Ammonia (NH3) is an important atmospheric pollutant due to its contribution to secondary
inorganic aerosol formation and its deposition and impacts on (semi-) natural ecosystems …

Large uncertainties and challenges remain in the quantification of land-atmosphere
exchanges of ammonia (NH 3), mainly due to limitations in measurement techniques. In this …

The reliable observation and accurate estimates of land–atmosphere water vapor (H2O) flux
is essential for ecosystem management and the development of Earth system models …

This study investigated the physicochemical properties of PM2. 5, especially among
secondary aerosols, based on the particulate matter and gaseous precursors in Yongin …

Dry deposition of ammonia (NH 3) is the largest contributor to the nitrogen deposition from
the atmosphere to soil and vegetation in the Netherlands, causing eutrophication and loss of …

Deposition of reactive nitrogen causes detrimental environmental effects, including
biodiversity loss, eutrophication, and soil acidification. Measuring and modeling the …
