The climatic effects of climate engineering—or geoengineering—via cirrus cloud thinning are examined. Thinner cirrus clouds can allowmore outgoing longwave radiation to escape to space, potentially cooling the climate. The cloud properties and climatic effects due to perturbing the ice crystal fall speed are investigated in a set of hemispheric scale sensitivity experiments with the Community E...

Abstract – Time-series of global outgoing radiation fields have been reconstructed for the last 20 years using satellite observations from various space systems including some Russian systems. It was detected that during the past two decades global outgoing longwave radiation (OLR) increased (considerably...

Anthropogenically induced climate change is of great current interest because of increases in atmospheric loading of infrared active (greenhouse) gases over the past 150 years and the inferred resultant increase in infrared radiation flux in the troposphere. However the climate change ascribed to such increases, not to mention predictions of future climate change in response to prospective chan...

The pH sensor exploits the phenomenon of upconversion luminescence and is based on a hydrogel matrix containing (a) nanorods of the NaYF(4):Er,Yb type that can be excited with 980-nm laser light to give a green and red (dual) emission, and (b) a longwave absorbing pH probe that causes a pH-dependent inner filter effect.

The paper presents an analysis by using the methods of Eddy field calculation mean and wavelet maxima to detect seismic anomalies within the outgoing longwave radiation (OLR) data based on time and space. The distinguishing feature of the method of Eddy field calculation mean is that we can calculate “the total sum of the difference value” of “the measured value” between adjacent points, which ...

In this paper the clear-sky infrared radiation field of the Earth-atmosphere system is characterized by the spectral decomposition of the simulated upward and downward flux density components into three distinct wave number regions. The relative contributions of the far infrared, middle infrared, and windows spectral regions to the total longwave flux densities have been established. The approx...

The effect of temperature on fluorescence and emission anisotropy spectra of 4-cyano-N,Ndimethylaniline (CDMA) was investigated in viscous (glycerol and paraffin oil) and rigid (polyvinyl alcohol) PVA and polyvinyl chloride) PVC) media. A strong effect of temperature on the intensity of a and b emission bands was observed. It was also found that the emission anisotropy, r, does not vary in the ...
