   An additional finding of this research was the importance of the shade-net which is modelled by a thin film in the study shown in Figure 5. [5] It not only provides cooling, but also elongates the cooling plume by containing the cold air plume from the evaporative cooling pad. [5]

3. Reflective surfaces (climate engineering) - Wikipedia

   en.wikipedia.org/wiki/Reflective_surfaces...

   The albedo of several types of roofs (lower values means higher temperatures). Reflective surfaces, or ground-based albedo modification (GBAM), is a solar radiation management method of enhancing Earth's albedo (the ability to reflect the visible, infrared, and ultraviolet wavelengths of the Sun, reducing heat transfer to the surface).

4. Connecticut shade tobacco - Wikipedia

   en.wikipedia.org/wiki/Connecticut_shade_tobacco

   The technique of growing shade tobacco has changed little in the past hundred years. To form the shade tents, a tobacco field is set with posts in a grid layout. Wires are stretched from post to post, and a light, durable fabric (once cotton but now a synthetic fiber) is tied across them and draped along the sides. For example, twenty posts in ...

5. Albedo - Wikipedia

   These factors vary with atmospheric composition, geographic location, and time (see position of the Sun). While directional-hemispherical reflectance factor is calculated for a single angle of incidence (i.e., for a given position of the Sun), albedo is the directional integration of reflectance over all solar angles in a given period. The ...

   Shade 1 is slightly grey and is usually categorized by air pollution boards as acceptable. It corresponds to an opacity of 20%. Shades 2, 3, 4 and 5 correspond to opacities of 40%, 60%, 80% and 100% (completely black) and are usually considered to be "black smoke" by air pollution boards of most countries.
