The table below ranks the sites from highest to lowest WFAR Annual Index. The coastal sites of Rabat and Casablanca have a good water-from-air resource allowing year-round effective operation of water-from-air systems.
At the higher elevation inland sites of Marrakech and Aguerdi, the water vapour resource in the low sun season decreases to the point where water-from-air systems will have unreliable water production during some periods. Hourly water production analyses are useful for better understanding the feasibility of water-from-air system operation at the inland cities.
