Site Coordinates and Elevation:

  • Latitude: 26.56944° South
  • Longitude: 26.93917° East
  • Elevation: 1480.0 Meters

Site Description:
  • The Welgegund measurement site is positioned approximately 25 km north-west of Potchefstroom. The sunphotometer is installed on the top of one of the containers containing other instruments owned by the Chemistry section of the University. The area surrounding the measurement station is grassland savannah grazed by cattle and sheep. The annual average temperature in the area is around 18 degrees, with typical maximum summer temperatures around 300 C and minimum winter temperatures around 0o C. The precipitation over the area falls during the wet season starting in October and lasting until April. The dry winter season with almost no precipitation is from mid-May until mid-September. There are very few local pollution sources close to the site, but it is frequently hit by pollution plumes from Johannesburg greater metropolitan area. These plumes are often balanced with clean air injections from the western sector
