This dataset contains potential gradient, visibility, standard meteorological data, and aerosol/droplet size and number concentration measurements used in the PhD thesis "Investigating The Electrical Modification of Fog In The UAE".  The data were collected from two locations in Dubai, United Arab Emirates (UAE): Sanad Academy and Al Marmoom (24°56' N, 55°30' E; 25°00' N, 55°30' E, respectively).

Electric field was measured by a Campbell CS110 electric field mill at 3m height (which was then converted to potential gradient using electric field = -potential gradient). Visibility was measured by a Biral SWS-100 visibility sensor on the same mast as the CS110. Standard meteorological data were initially obtained from Al Marmoom site from February 2021 to January 2022, after which it was installed in Sanad Academy. Droplet size and number concentration data were collected using a light optical aerosol counter (LOAC), which was deployed only during forecasted fog events.
