Clicking on the book cover images above will take you to Amazon where you can choose to order a paperback copy of the atlas. 

An outstanding guide for decision-making about the use of atmospheric water generators (AWGs) in West Asia (Middle East). Contents include maps of monthly specific humidity fields, water-from-air performance analyses for 121 selected locations (comparing performance by month of chilled-coil AWGs and solid desiccant AWGs),  technical appendices, and a list of AWG suppliers in West Asia. Order your eBook at the Atmoswater Shop.

A valuable guide for decision-making about the use of atmospheric water generators (AWGs) in Texas!

I enjoyed reading this article about water-from-air technologies in the 3 July 2025 issue of "Science". An online version appears to be open access at https://www.science.org/content/article/devices-pull-water-out-thin-air-poised-take

Typical water-from-air resource chart. Praia has an annual index of 0.86. This value is the monthly average water vapour density divided by 15.3 g/cubic m. This latter value is the water vapour density at standard conditions of 26.7° C dry bulb temperature and 60% relative humidity and 1 atmosphere air pressure (sea level). Click to enlarge chart.

A conventional catalogue format somehow makes it easier (as compared to browsing a website) to comprehend our interesting and useful range of knowledge-products! Take a look.

[Text excerpted and adapted from Technical Bulletin No. 5 (revised 2023)—Environmental impact of widespread use of drinking-water-from-air systems issued by Canadian Dew Technologies Inc.This blog post supersedes two earlier blog posts on the same topic (My answers to questions asked in Oct. 20, 2020 Webinar: Introduction to Atmospheric Water and Impact on the atmospheric water reservoir from using water-from-air systems: an update) The human population keeps increasing and estimates have been refined of the atmospheric water reservoir volume.Concern has been expressed by some potential users of WFA systems that widespread use in a region could decrease the water vapour content of the atmosphere. If this was the case, would regional weather and climate be affected?Assessing Environmental Impact on the Atmospheric Water ReservoirEarth’s estimated human population is now 8 billion, projected to increase to 10.4 billion in 2100 (https://population.un.org/dataportal/home) so the 1993 worst-case impact estimate was updated as follows in the next paragraph, incorporating a revised per capita water consumption value of 50 L/day as suggested by Gleick (1998) for domestic water requirements (drinking, kitchen, laundry, and bath). Revised water cycle information was from Abbott et al. (2019).The atmosphere contains 12.9 × 10^12 m^3 of water or 0.001% of the Earth’s total water reservoir volume of 1.38 × 10^18 m^3. Water reservoirs include the atmosphere, ice and snow, biomass, surface water, underground water, and the oceans. Even if all 8 × 10^9 people on Earth used water from water vapour processors at the rate of 50 litres per day, they would consume only 0.003% of the available atmospheric water. In 2100, when population is expected to rise to 10.4 × 10^9, this worst-case impact would rise slightly to 0.004%.  Water vapour, the gas phase of water, diffuses along pressure gradients to zones of lower water vapour pressure. If a lot of water vapour was condensed into liquid water in a specific region such as a city, water vapour from outside the region would flow into the region. No net loss of atmospheric water vapour would be observed in the city.Water consumed for domestic water requirements does not exit from the water cycle. Within a day the water that is used or temporarily withheld from the water cycle would be returned to the environment to evaporate into atmospheric water vapour.

I trust you are enjoying your visit to Atmoswater Research and are gaining some valuable knowledge about water-from-air topics. Since 1999 the Atmoswater Research website has endeavored to provide the water-from-air community with accurate scientific & technical information---with a lot being free to access. Although consulting contracts, sales of digital goods, and advertising revenue give us an income stream it is far from being predictable and steady. Maintaining and improving this site requires a certain amount of cash flow. Therefore, we have added a "coffee jar" for those who would like to support us financially but do not have an immediate need for consulting services, digital goods, or an advertising spot. The "Buy me a coffee!" button is located on our home page, right-hand column (bottom; scroll down). Clicking the button below also opens the coffee jar which is a secure page in the PayPal system. Thanks very much for your support!-Roland Wahlgren
