Atmospheric scientists study fires to resolve ice question in climate models（图）
Atmospheric scientists fires resolve ice question climate models
2020/9/4
When fossil fuel or biomass burns, soot -- also known as black carbon -- fills the air. Black carbon is an important short-term climate driver because it absorbs solar energy and can affect the format...
Black carbon persists in snow and ice around the world
Black carbon persists snow ice around the world
2017/7/24
A new CU Boulder study comparing dissolved black carbon deposition on ice and snow in ecosystems around the world (including Antarctica, the Arctic and alpine regions of the Himalayas, Rockies, Andes ...
Influence of convection and aerosol pollution on ice cloud particle effective radius
convection and aerosol pollution ice cloud particle radius
2011/1/20
Satellite observations show that ice cloud effective radius (re) increases with ice water content (IWC) but decreases with aerosol optical thickness (AOT). Using least-squares fitting to the observed ...
Assessing observed and modelled spatial distributions of ice water path using satellite data
observed and modelled spatial ice water path satellite data
2011/1/19
The climate models used in the IPCC AR4 show large differences in monthly mean ice water path (IWP). The most valuable source of information that can be used to potentially constrain the models is glo...
Observations of ice multiplication in a weakly convective cell embedded in supercooled mid-level stratus
ice multiplication a weakly convective cell supercooled mid-level stratus
2011/1/19
Simultaneous observations of cloud microphysical properties were obtained by in-situ aircraft measurements and ground based Radar/Lidar. Widespread mid-level stratus cloud was present below a temperat...
Manchester Ice Nucleus Counter (MINC) measurements from the 2007 International workshop on Comparing Ice nucleation Measuring Systems (ICIS-2007)
Manchester Ice Nucleus Counter the 2007 International workshop Ice nucleation Measuring Systems
2011/1/18
An ice nucleus counter was developed and constructed to enable investigation of potential ice nucleating materials. The Manchester Ice Nucleus Chamber (MINC) is a concentric-cylinder continuous flow d...
Diurnal variations of humidity and ice water content in the tropical upper troposphere
humidity and ice water content the tropical upper troposphere
2010/12/20
Observational results of diurnal variations of humidity from Odin-SMR and AURA-MLS, and cloud ice mass from Odin-SMR and CloudSat are presented for the first time. Comparisons show that the retrievals...
Aerosol effects on ice clouds: can the traditional concept of aerosol indirect effects be applied to aerosol-cloud interactions in cirrus clouds?
Aerosol effects ice clouds aerosol indirect effects aerosol-cloud interactions cirrus clouds
2010/11/29
Cirrus clouds cover approximately 20–25% of the globe and thus play an important role in the Earth's radiation budget. Therefore the effect of aerosols on cirrus clouds can have a substantial impact o...
Surface measurements of aerosol and ice nuclei (IN) at a Central European mountain site during an episode of dust transport from the Sahara are presented. Ice nuclei were sampled by electrostatic prec...
The potential influence of Asian and African mineral dust on ice, mixed-phase and liquid water clouds
Asian and African mineral dust ice mixed-phase liquid water clouds
2010/9/21
This modelling study explores the availability of mineral dust particles as ice nuclei for interactions with ice, mixed-phase and liquid water clouds, also tracking the particles' history of cloud-pro...
In addition to microphysical changes in clouds, changes in nucleation processes of ice cloud due to aerosols would result in substantial changes in cloud top temperature as mildly supercooled clouds a...
Combining visible and infrared radiometry and lidar data to test simulations in clear and ice cloud conditions

2010/8/16
Measurements taken during the 2003 Pacific THORPEX Observing System Test (P-TOST) by the MODIS Airborne Simulator (MAS), the Scanning High-resolution Interferometer Sounder (S-HIS) and the Cloud Physi...
Post-coring entrapment of modern air in some shallow ice cores collected near the firn-ice transition: evidence from CFC-12 measurements in Antarctic firn air and ice cores
modern air shallow ice cores the firn-ice transition CFC-12 measurements Antarctic firn air and ice cores
2010/8/13
In this study, we report measurements of CFC-12 (CCl2F2) in firn air and in air extracted from shallow ice cores from three Antarctic sites. The firn air data are consistent with the known atmospheric...
Parametric studies of contrail ice particle formation in jet regime using microphysical parcel modeling
contrail ice particle formation jet regime microphysical parcel modeling
2010/8/12
Condensation trails (contrails) formed from water vapor emissions behind aircraft engines are the most uncertain components of the aviation impacts on climate change. To gain improved knowledge of con...
A new modeling tool for the diffusion of gases in ice or amorphous binary mixture in the polar stratosphere and the upper troposphere
the diffusion of gases ice or amorphous binary mixture the polar stratosphere the upper troposphere
2010/8/12
To elaborate stratospheric ozone depletion processes, measurements of diffusion coefficients of selected gas phase molecules (i.e. HCl, CH3OH, HCOOH and CH3COOH; Katsambas et al., 1997; Kondratyev and...
