Measurements of Gaseous NH3 and Particulate NH4 + in the Atmosphere by Fluorescent Detection after Continuous Air–water Droplet Sampling
Ammonia Gas-particle partitioning Microflow analysis Short-term variation
2016/3/28
Phase partitioning of NHx (gaseous NH3 and particulate NH4
+) in the atmosphere is crucial for the lifetime of NHx
during atmospheric transport. Reliable data for gaseous NH3 and NH4
+ in aerosols ...
A global survey of aerosol-liquid water cloud overlap based on four years of CALIPSO-CALIOP data
aerosol-liquid water cloud CALIPSO-CALIOP data
2011/2/25
Simulating the radiative impacts of aerosols located above liquid water clouds presents a significant challenge. In particular, absorbing aerosols, such as smoke, may have significant impact in such s...
Water content of aged aerosol
Water aged aerosol
2011/2/25
The composition and physical properties of aged atmospheric aerosol were characterized at a remote sampling site on the northern coast of Crete, Greece during the Finokalia Aerosol Measurement Experim...
Impact of biomass burning on ocean water quality in Southeast Asia through atmospheric deposition: field observations
biomass burning ocean water quality Southeast Asia atmospheric deposition field observations
2010/12/20
Atmospheric nutrients have recently gained considerable attention as a significant additional source of new nitrogen (N) and phosphorus (P) loading to the ocean. The effect of atmospheric macro nutrie...
A model study on the influence of overshooting convection on TTL water vapour
overshooting convection TTL water vapour
2010/10/21
Overshooting deep convection that penetrates into the Tropical Tropopause Layer (TTL) is thought to have an important role in regulating the water vapour content of this region. Yet, the net effect of...
Tomographic retrieval of cloud liquid water fields from a single scanning microwave radiometer aboard a moving platform – Part 2: Observation system simulation experiments
