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 "tip 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 tip jar is located on our home page, right-hand column (bottom; scroll down). Clicking the button below also opens the tip jar which is a secure page in the PayPal system. Thanks very much for your support!
