Abstract

Using a numerical integration (Lowtran 6 code) stopped at several arbitrary base altitudes, in association with measurements from sounding balloons, clear sky radiation is determined as a function of the altitude parameter. The relations established, and the properties attached, are studied. In application, a natural system to obtain dew in dry climates is explained.

    Because the empirical coefficient values can have substantial effects on predicted dew yield, a parametric sensitivity analysis was performed on both a and d using the one-at-a-time method by varying input parameters ± 20% because they were obtained from 10 experimental stations (Beysens, 2016), and monitoring the output. No sensitivity analysis was performed on the other coefficients (b and c) because sky emissivity (b) was based on a widely tested empirical model (Berger and Bathiebo, 1992), which considers the night sky in addition to Td. Similarly, the maximum wind velocity (c) is equally valid based on a review of global experimental studies (Tomaszkiewicz et al., 2015).

    In case of a cloudless sky, the sky temperature in zenith direction is always relatively low whereas in other directions it is much higher. This phenomenon is caused by the increase of the length of path radiation beam in atmospheric air [15,27]. In Figs. 4 and 5 the examples of sky temperature measurements with the use of LW infrared camera for the case of relatively cold and non-isothermal sky and for “warm” and isothermal one, can be seen.
