“…Particularly, the water vapor and the CO 2 in air are strong factors for variation in the transmission of the laser pulse propagating in air [15]. The transmission of the standard atmosphere (T w ) with respect to the water vapor (P w ) can be written as [17], …”

“…where β (λ) and γ(λ) are the empirical parameters which are closely related to the line strength in the spectra line induced by molecular collisions based on CO2 [15]. Figure 3(b) shows the transmission variation of the standard atmosphere (Tc) with variations in the concentration of CO2.…”

“…CO2 absorbs the optical power of the pulse laser resulting in the variation of the transmission of the standard atmosphere for the 200-m round trip distance of femtosecond laser through air. We considered two operating wavelengths with weak absorption bands of CO2, such as 1400 nm and 1600 nm [15]. By considering Eq.…”

“…The refractive index of air is analyzed with respect to the atmospheric conditions [12,13]. The absorption of air related to the molecules of air constituents is investigated [14][15][16]. However, it is not enough to analyze the propagation characteristics of the pulse laser traveling in the air including group velocity, pulse width broadening, and transmission.…”

We investigate the propagation characteristics of a pulse laser in a time-of-flight laser range finder (TOF-LRF) system with variations in atmospheric conditions, such as temperature, pressure, relative humidity, and the concentration of CO2. The measurement error of distance related with the group velocity change in the TOF-LRF system is analyzed by considering the refractive index of the standard atmosphere with variations in atmospheric conditions. The dependence of the pulse width broadening induced by chromatic dispersion of the standard atmosphere on the operating wavelength and the initial pulse width of the light sources is discussed. The transmission of air with variations in the relative humidity or the concentration of CO2 is analyzed by using different values of absorption coefficients depending on the operation wavelength of the light source in the TOF-LRF system.

Studies of a numerical model of fog are presented. These indicate that: (i) For given initial conditions, a reduction in turbulent diffusion leads to earlier and thicker fog formation.(ii) The formation and growth of fog on a realistic time scale is simulated by the inclusion of radiative cooling due to water vapour and carbon dioxide and (when formed) fog droplets.(iii) The inclusion of gravitational settling is necessary to simulate realistic liquid water contents.(iv) The nature of the underlying surface (through its thermal properties) influences the time of onset of fog.The effect of cloud cover and of solar insolation on dispersing fog was assessed. These results are broadly consistent with, and help to account for, the results of a parallel field study by Roach, Brown, Caughey, Garland and Readings (1976).
