Evaporative processes at the air-earth interface are examined in terms of a moisture availability coefficient. A postulate is formed for developing the availability coefficient utilizing the ratio of potential evaporation to actual evaporation. Experimental data is used to evaluate this approach and results indicate that the moisture availability coefficient appears to be independent of climate, season of the year or latitude and soil type. A preliminary study of the effects of atmospheric water vapor on the dynamic stability of the surface boundary layer was also undertaken.
