چکیده انگلیسی
In this work, water vapor radiative effect (WVRE) is studied by means of the Santa Barbara's Disort Radiative Transfer (SBDART) model, fed with integrated water vapor (IWV) data from 20 ground-based GPS stations in Spain. Only IWV data recorded during cloud-free days (selected using daily insolation data) were used in this study. Typically, for SZAâ¯=â¯60.0 ± 0.5° WVRE values are around â 82 and â 66 Wmâ2 (first and third quartile), although it can reach up â 100 Wmâ2 or decrease to â 39 Wmâ2. A power dependence of WVRE on IWV and cosine of solar zenith angle (SZA) was found by an empirical fit. This relation is used to determine the water vapor radiative efficiency (WVEFFâ¯=â¯âWVRE/âIWV). Obtained WVEFF values range from â 9 and 0 Wmâ2â¯mmâ1 (â 2.2 and 0%â¯mmâ1 in relative terms). It is observed that WVEFF decreases as IWV increases, but also as SZA increases. On the other hand, when relative WVEFF is calculated from normalized WVRE, an increase of SZA results in an increase of relative WVEFF. Heating rates were also calculated, ranging from 0.2 Kdayâ1 to 1.7 Kdayâ1. WVRE was also calculated at top of atmosphere, where values ranged from 4 Wmâ2 to 37 Wmâ2.
