2023/6/26
Kim Cobb, a Brown University professor and director of the Institute at Brown for Environment and Society, spoke about the need to act on climate change, urging that action must be taken collaborative...
Impact of parametric uncertainties on the present-day climate and on the anthropogenic aerosol effect
parametric uncertainties the present-day climate the anthropogenic aerosol effect
2010/12/20
Clouds constitute a large uncertainty in global climate modeling and climate change projections as many clouds are smaller than the size of a model grid box. Some processes, such as the rates of rain ...
Comparison of a global-climate model to a cloud-system resolving model for the long-term response of thin stratocumulus clouds to preindustrial and present-day aerosol conditions
a global-climate model a cloud-system resolving model thin stratocumulus clouds present-day aerosol conditions
2010/8/16
The response of a case of thin, warm marine-boundary-layer (MBL) clouds to preindustrial (PI) and present-day (PD) conditions is simulated by a cloud-system resolving model (CSRM). Here, both the aero...
IASI observations of seasonal and day-to-day variations of tropospheric ozone over three highly populated areas of China: Beijing, Shanghai, and Hong Kong
IASI observations seasonal and day-to-day variations tropospheric ozone three highly populated areas of China
2010/8/12
IASI observations of tropospheric ozone over the Beijing, Shanghai and Hong Kong areas during one year (2008) have been analysed, demonstrating the capability of space-borne infrared nadir measurement...
27-day variation in cloud amount in the Western Pacific warm pool region and relationship to the solar cycle
Western Pacific warm pool region solar cycle
2010/2/21
Although linkages between solar activity and the earth's climate have been suggested and the 11-year cycle in solar activity evident in sunspot numbers is the most examined example of periodicity in p...
The 16-day wave in the Arctic and Antarctic mesosphere and lower thermosphere
16-day wave Arctic and Antarctic mesosphere lower thermosphere
2010/2/21
The 16-day planetary wave in the polar mesosphere and lower thermosphere has been investigated using meteor radars at Esrange (68° N, 21° E) in the Arctic and Rothera (68° S, 68° W) in the Antarctic. ...
Late Glacial to Holocene environments in the present-day coldest region of the Northern Hemisphere inferred from a pollen record of Lake Billyakh, Verkhoyansk Mts, NE Siberia
Holocene environments Northern Hemisphere coldest region
2009/12/3
In this study, a radiocarbon-dated pollen record from Lake Billyakh (65°17' N, 126°47' E; 340 m a.s.l.) in the Verkhoyansk Mountains was used to reconstruct vegetation and climate change since about 1...
On the two-day oscillations and the day-to-day variability in global 3-D-modeling of the chemical system of the upper mesosphere/mesopause region
two-day oscillations day-to-day variability global 3-D-modeling chemical system
2009/11/11
The integration of the photochemical system of the upper mesosphere/mesopause region brought evidence that the system is able to respond in a nonlinear manner under certain conditions. Under the actio...
The two-day wave in the Antarctic and Arctic mesosphere and lower thermosphere
two-day wave Antarctic Arctic mesosphere lower thermosphere
2009/9/11
There have been comparatively few studies reported of the 2-day planetary wave in the middle atmosphere at polar latitudes. Here we report on a study made using high-latitude meteor radars at Rothera ...
Day-time concentrations of biogenic volatile organic compounds in a boreal forest canopy and their relation to environmental and biological factors
Day-time concentrations biogenic volatile organic compounds boreal forest canopy environmental and biological factors
2009/8/7
Atmospheric concentrations of methanol, acetaldehyde, acetone, isoprene and monoterpenes were measured using PTR-MS (proton transfer reaction mass spectrometry) in a boreal forest site in Hyytiäl...

Radicals in the marine boundary layer during NEAQS 2004: a model study of day-time and night-time sources and sinks
marine boundary layer NEAQS Radicals
2009/5/15
This paper describes a modelling study of several HOx and NOx species (OH, HO2, organic peroxy radicals, NO3 and N2O5) in the marine boundary layer. A model based upon the Master Chemical Mechanism (M...
Sensitivity of aerosol and cloud effects on radiation to cloud types: comparison between deep convective clouds and warm stratiform clouds over one-day period
aerosol cloud types deep convective clouds warm stratiform clouds
2009/5/7
Cloud and aerosol effects on radiation in two contrasting cloud types, a deep mesoscale convective system (MCS) and warm stratocumulus clouds, are simulated and compared. At the top of the atmosphere,...
