Abstract from my article published February 11, 2014 on Water Online:

Quantifying the water-from-air resource enables targeting selected cities where installing strategically located stand-alone processors of atmospheric water vapor will have the quickest, most beneficial impact for people facing water scarcities.

#Atlas of the #Water-from-Air Resource for #China

Sample page from the Atlas of the Water-from-Air Resource for China

Sample page from the Atlas (click to enlarge).

The water-from-air resource for China is presented as a series of monthly colour-shaded maps. The resource is graded as being excellent, good, fair, or poor. The grading is based on specific humidity data at the 1000 mb pressure level. The data is from the USA’s National Oceanic and Atmospheric Administration. The grading system for the maps is designed to be compatible with the grading system used on the Water-from-Air Resource Charts issued by Atmoswater Research for various sites.

These maps offer a quick survey of the water-from-air resource in China. Decisions about deployment of water-from-air systems should also include knowledge from monthly models (suitable for tropical regions with monthly grades consistently ‘good’ to ‘excellent’) and hourly models (essential for temperate regions with variable monthly grades).

#China #Water-from-Air Resource Charts

China location map (with latitude and longitude) showing locations which have available water-from-air resource charts (click on image to enlarge).

Water-from-Air Resource (WFAR) Charts are available for seventeen sites in China. Operating conditions by month for atmospheric water generators range from poor to excellent depending on site latitude, elevation, and season. Please see the charts for details.

The table below ranks the sites from highest to lowest WFAR Annual Index. Generally, water-from-air system performance is better at more southerly sites. Performance is better along the coast than further inland. During the summer months of July and August, when drinking water scarcity is likely to affect people most, water-from-air systems will offer excellent performance except for Hohhot (fair), Taiyuan (good), and Kunming (good).

China appears to be a worthwhile market for drinking-water-from-air technologies. At least three equipment suppliers are based in the country.
