  the S spectra established that the dominant molecular forms of S present were sulfate (26-84% of total S) and thiophene (13-39% of total S). Sulfate was greater in the PM2.5 samples than in the PM2.5+ samples. Inorganic sulfides and elemental sulfur were present in lower percentages. The Ni XANES spectra from all of the samples agreed fairly well with that of NiSO4, while most of the V spectra closely

  The UV and global solar radiation on a horizontal surface at ground level in Riyadh City (latitude 24 degrees 34' N, longitude 46 degrees 43' E) have been measured and analyzed. Measurements of UV radiation (295-385 nm) were recorded every 10 min for five years (January 1983-December 1987). The maximum recorded hourly mean irradiance UV radiation was 28 W/m(2) and occurred in July, while the minimum was 14 W/m(2) in December. A steady monthly value of K-vh = (UV/H) was obtained and equaled 2.9%. A similar trend was found for the monthly variation of K-t = (H/H-o) and K-v = (UV/H-o) Maximum values of 90% and 2.6% were recorded in June for K-t and K-v, respectively, while minimum values of 35% and 1%, respectively, were obtained in December. A linear correlation was obtained between K-v and K-t. These findings were discussed and connected to the meteorological events. The results were compared with the regions of Kuwait, Bahrain, Dhahran, and Makkah.
