| PWAT | Precipitable water | kg/m2 | Precipitable water is the depth of water vapour in a column of the atmosphere, if all the water in that column were precipitated as rain. It indicates the amount of moisture above ground. |

Solar radiation data is available from years as indicated on the map above. Data for the sites in a shaded areas is generated manually upon request.
For other meteorological parameters data is available from year 1994 for all regions.
Ground albedo data is available from year 2000.
