Charts for selected cities

• Sorted alphabetically by continent, country,  and city .
• These analyses are independent of the water-from-air equipment being used.
• When the water-from-air resource monthly index = 1.00, the expected drinking water production rate from a atmospheric water generator (AWG) at the site should be the same as the machine's specified water-from-air production rate.
• Water-from-Air Resource annual index grades

        Excellent: Index greater than or equals 1
        Good: Index range 0.76 to 0.99
        Fair: Index range 0.51 to 0.75
        Poor: Index less than or equal to 0.50

• Estimate the daily drinking water production rate at a site with this method (chilled surface temperature = 5°C; WFAR index less than or equal to 1.00):
  (1) Use water-from-air system's specified production rate (for example: 20 L/day; 2500 L/day)
  (2) Use the annual or monthly Water-from-Air Resource (WFAR) index value from the WFAR chart for your site
  (3) Calculate the factor = (1.8 x index - 0.8) [dimensionless]
  (4) Estimate [L/day] = specified rate [L/day] x factor
  
  Example: Specified rate = 20 L/day; Index = 0.91; Factor = (1.8 x 0.91 - 0.8) = 0.838; Estimate = 20 L/day x 0.838 = 17 L/day.

• When the water-from-air resource index is greater than 1.00, the machine's maximum water production rate is constrained by the equipment's cooling capacity (for example, atmospheric water generators which are dehumidifiers condensing water vapour onto chilled surfaces). It is safest to say production rate = specified rate.
