Reply to: “Tropical cirrus and water vapor: an effective Earth infrared iris feedback?”
Tropical cirrus water vapor effective Earth infrared iris feedback
2009/3/12
In assessing the iris effect suggested by Lindzen et al. (2001), Fu et al. (2002) found that the response of high-level clouds to the sea surface temperature had an effect of reducing the climate sens...
Tropical cirrus and water vapor: an effective Earth infrared iris feedback?
Tropical cirrus water vapor effective Earth infrared iris feedback
2009/3/11
We revisit a model of feedback processes proposed by Lindzen et al. (2001), in which an assumed 22% reduction in the area of tropical high clouds per degree increase in sea surface temperature produce...
Stratospheric water vapour as tracer for Vortex filamentation in the Arctic winter 2002/2003
Stratospheric water vapour Vortex filamentation Arctic winter
2009/3/11
Balloon-borne frost point hygrometers measured three high-resolution profiles of stratospheric water vapour above Ny-Ålesund, Spitsbergen during winter 2002/2003. The profiles obtained on 12 Dec...
Effect of water addition and nitrogen fertilization on the fluxes of CH4, CO2, NOx, and N2O following five years of elevated CO2 in the Colorado Shortgrass Steppe
nitrogen fertilization CH4 CO2 NOx N2O Colorado Shortgrass Steppe
2009/3/11
An open-top-chamber (OTC) CO2 enrichment (~720 mmol mol-1) study was conducted in the Colorado shortgrass steppe from April 1997 through October 2001. Aboveground plant biomass increased under elevate...
Inelastic scattering in ocean water and its impact on trace gas retrievals from satellite data
Inelastic scattering ocean water trace gas retrievals satellite data
2009/3/11
Over clear ocean waters, photons scattered within the water body contribute significantly to the upwelling flux. In addition to elastic scattering, inelastic Vibrational Raman Scattering (VRS) by li...
The rate of water vapor evaporation from ice substrates in the presence of HCl and HBr: implications for the lifetime of atmospheric ice particles

Using a multidiagnostic approach the rate Rev [ molec cm-3 s-1] or flux Jev [ molec cm-2 s-1] of evaporation of H2O and its corresponding rate constant for condensation, kcond [s-1 ], on a 1 µm ...
Application of the Spectral Structure Parameterization technique: retrieval of total water vapor columns from GOME
Spectral Structure Parameterization technique total water vapor columns GOME
2009/3/10
We use a recently proposed spectral sampling technique for measurements of atmospheric transmissions called the Spectral Structure Parameterization (SSP) in order to retrieve total water vapor columns...
Noctilucent clouds and the mesospheric water vapour: the past decade
Noctilucent clouds mesospheric water vapour
2009/3/10
The topic of this paper is the sensitivity of the brightness of noctilucent clouds (NLC) on the ambient water vapour mixing ratio f(H2O). Firstly, we use state-of-the-art models of NLC layer formation...
Global warming has become an important environmental issue, and water is the resource most directly affected by climate change. Global warming will alter the amount and spatial distribution of availab...
Actinic flux and photolysis in water droplets：Mie calculations and geometrical optics limit
Actinic flux photolysis water droplets Mie calculations geometrical optics limit
2009/3/9
Photolysis of water-soluble components inside cloud droplets by ultraviolet/visible radiation may play an important role in atmospheric chemistry. Two earlier studies have suggested that the actinic f...
Ground-based water vapour soundings by microwave radiometry and Raman lidar on Jungfraujoch （Swiss Alps）
Ground-based water vapour microwave radiometry Raman lidar
2009/3/9
Water vapour has been measured from the International Scientific Station Jungfraujoch (ISSJ, 47° N, 7° E, 3580m above sea level) during the winters of 1999/2000 and 2000/2001 by microwave radiometry a...
A quartz crystal microbalance apparatus has been used to measure the room temperature uptake of water vapour by thin films of oleic acid as a function of relative humidity, both before and following e...
Laboratory evidence for volume-dominated nucleation of ice in supercooled water microdroplets
Laboratory evidence volume-dominated nucleation of ice supercooled water microdroplets
2009/3/6
We report on measurements of the rate of homogeneous ice nucleation in supercooled water microdroplets levitated in an electrodynamic balance. By comparison of the freezing probability for droplets of...
Remote sensing of water cloud droplet size distributions using the backscatter glory: a case study
water cloud droplet size distributions backscatter glory Remote sensing
2009/3/3
Cloud single scattering properties are mainly determined by the effective radius of the droplet size distribution. There are only few exceptions where the shape of the size distribution affects the op...
