Thirteen equations based on the mass-transfer method for determining free water evaporation were expressed in seven generalized equations. These seven equations were then compared with pan evaporation at four climatological stations in north-western Ontario, Canada. The comparisons were based on monthly evaporation. Equations were compared by calibrating them on the entire data sets as well as ...

The impact of interannual variability of precipitation and potential evaporation on the long-term mean annual evapotranspiration as well as on the interannual variability of evapotranspiration is studied using a stochastic soil moisture model within the Budyko framework. Results indicate that given the same long-term mean annual precipitation and potential evaporation, including interannual var...

Literature regarding evaporation from soil, wet plant surfaces, and sprinkler droplets was examined, normalized, and inter­ preted. Much of the evaporation literature is difficult to compare and interpret; this paper offers comparisons and discussions of various findings by others as well as by the writers. Techniques of measuring and estimating evaporation from irrigation and rainfall are disc...

Solvent loss due to evaporation in a drying drop can drive capillary flows and solute migration. The flow is controlled by the evaporation profile and the geometry of the drop. We predict the flow and solute migration near a sharp corner of the perimeter under the conditions of uniform evaporation. This extends the study of Popov and Witten [Phys. Rev. E 68, 036306 (2003)], which considered a s...

Monthly composites of the Normalized Difference Vegetation Indices (NDVI), derived from the National Oceanic and Atmospheric Administration's (NOAA) Advanced Very High Resolution Radiometer (AVILRR), were transformed linearly into monthly evaporation rates and compared with detailed hydrologic-model simulation results for five watersheds across the United States. Model-simulated monthly evapora...

The precipitation in the Qilian (QMA) and Tienshan (TMA) mountain areas is one of main sources subsurface surface water northwestern China (NWC). Based on two datasets, CN05.1 station-observed daily precipitation, we found that summer 1979–2020 exhibited an increasing trend NWC. results rotation empirical orthogonal function (REOF) analysis also separated increased patterns QMA TMA from other R...

  Background and aims: Production of fixed concentration of vapors from pure liquid has many applications in laboratory and field studies of occupational health and toxicological research and also in calibration of air pollutant measurement devices of the workplaces. In this study, the advantages and disadvantages of different concentration generation methods were discussed. In addition two sel...

This report investigates the influence of surface chemistry (or wettability) on the evaporation performance of free-standing double-layered thin film on the surface of water. Such newly developed evaporation system is composed of top plasmonic light-to-heat conversion layer and bottom porous supporting layer. Under solar light illumination, the induced plasmonic heat will be localized within th...
