Periodically switching between evaporation and condensation, or "humidity cycling", has potential for controlling the film shape that results from volatile droplets containing a nonvolatile material. It does not require adaptation of material properties nor the introduction of an external field to achieve a change in film shape. It was shown experimentally by Doi and coworkers [Kajiya et al. La...

Atmospheric radon concentrations were monitored from autumn 2004 to winter 2007 in an abandoned coal mining area of SW Poland that contained various bedrock uranium contents, ranging from 1 to 8 ppm. Gamma spectrometric measurements of eU, eTh and K content in the bedrock were combined with radon-monitoring results at 77 points, obtained via Kodak LR-115 detectors. The average atmospheric radon...

The scalar flux–gradient relationships of temperature (φT ) and specific humidity (φq ) under unstable conditions are investigated using eddy-covariance measurements of air– sea turbulent fluxes and vertical profiles of temperature and specific humidity collected from a marine meteorological platform. The gradients of temperature and specific humidity are obtained frommeasurements at five heigh...

The 89 and 150 GHz channels operated in window are sensitive to precipitation and humidity. The 183 GHz humidity-sensitive channels and 118 GHz temperature-sensitive channels of the Microwave Humidity and Temperature Sounder (MWHTS) on the Chinese Feng Yun 3C MWHTS (FY-3C MWHTS) polar-orbit meteorological satellite responds in part to precipitation. Combining 118 and 183 GHz channels, the paper...

Understanding the risks of using commercial off-theshelf (COTS) electronic components, specifically laptop computers, in a non-commercial environment is critical to designers of military systems. The environment studied in this paper is that of an unpressurized aircraft cockpit operating at 35,000 feet. During operation in this environment, COTS may be exposed to low atmospheric pressure and ma...

The paper summarizes the performance characteristics of linear statistical regression approach to the inversion of advanced IR-sounders data and retrieval of atmospheric temperature, humidity and ozone concentration profiles. The retrieval experiments with synthetic IASI data demonstrate the ability of proposed techniques to derive rather accurate sounding products at a reasonable cost.

In the infrared and visible bandpass, optical propagation theory conventionally assumes that humidity does not contribute to the effects of atmospheric turbulence on optical beams. While this assumption may be reasonable for dry locations, we demonstrate in this paper that there is an unequivocal effect due to the presence of humidity upon the strength of turbulence parameter, C n, from data co...

The corrosion of Ag in an atmosphere of ozone and humidity with or without irradiation by ultraviolet (UV) light was investigated. A modified coulometric reduction technique was used, substituting sulphate solution for chloride solution, to prevent the spontaneous transformation of silver oxide corrosion product to chloride in the reduction solution. The presence of both ozone and UV radiation ...

The next generation of atmospheric temperature and humidity sounders will have thousands of radiometrically accurate spectral channels throughout the infrared. The retrieval of atmospheric parameters from these radiances will stress both the accuracy and efficiency of forward model radiative transfer algorithms. We are developing a forward model for the Atmospheric Infrared Sounder (AIRS) which...

Experimental investigations were carried out to study the effect of humidity on the breakdown of rod-plane gaps subjected to both uni-directional and bi-directional oscillatory switching impulse voltages. The humidity ranged from 14.1 36 gm/m3 at a constant temperature of 40' C. The gap subjected to uni-directional 6.3, 10, lQ kHz and bi-directional 4.2, 10,20 kHz oscillatory switching impulse ...
