Atmospheric ammonia (NH 3) released from agriculture is contributing significantly to
acidification and atmospheric NH 3 may have on human health is much less readily …

Acidity, defined as pH, is a central component of aqueous chemistry. In the atmosphere, the
acidity of condensed phases (aerosol particles, cloud water, and fog droplets) governs the …

Fundamental questions remain about the origin of newly formed atmospheric aerosol
particles because data from laboratory measurements have been insufficient to build global …

Since the mid-1990s a new generation of Earth-observing satellites has been able to detect
tropospheric air pollution at increasingly high spatial and temporal resolution. Most primary …

A general feature in the diurnal cycle of atmospheric ammonia (NH3) concentrations is a
morning spike that typically occurs around 07: 00 to 10: 00 (LST). Current hypotheses to …

Atmospheric ammonia (NH3) has great environmental implications due to its important role
in ecosystem and global nitrogen cycle, as well as contribution to secondary particle …

The limited availability of ammonia (NH3) measurements is currently a barrier to
understanding the vital role of NH3 in secondary aerosol formation during haze pollution …

In this paper, we review the current understanding on ecosystem and human health impacts
from the atmospheric deposition of acidifying pollutants, eutrophying nitrogen (N), polycyclic …

A portable laser sensor for trace ammonia (NH 3) is developed based on near-infrared laser
absorption spectroscopy. Tunable diode laser absorption spectroscopy in conjunction with …

Ammonia (NH3), the most prevalent alkaline gas in the atmosphere, plays a significant role
in PM2. 5 formation, atmospheric chemistry, and new particle formation. This paper reviews …
