Publications for Linke Turbidity factor: Remund et al. 2003, Diabaté et al. 2003

Inputs

  • Latitude and longitude of the point
  • Month in the year
  • Altitude: the altitude of the geographical site of simulation can be either extracted from the orography resource (if set to 0) or forced by the user by inputting a value greater than or equal to 1. Unit is meter. The orography resource has a grid cell of 5' of arc angle and uses the data base TerrainBase (TerrainBase, Worldwide Digital Terrain Data. Documentation Manual, CD-ROM Release 1.0, April 1995. NOAA, National Geophysical Data Center, Boulder, Colorado, USA).

Outputs

  • Water Vapor: total precip. water (NVAP, 1988-1997), unit=[cm]
  • Linke Turbidity factor: monthly mean, climatological values, unit= [ ]
  • Ozone: O3: Mean stratosph. ozone (GOME, 1996-2000), unit=[Dobson]
  • Angstroem Beta: BE (wv (NVAP, 1988-1997) / TL), unit=[ ]

Method

Water vapour (WV) or total precipital water is taken from NVAP and corresponds to mean values of 1988-97 (maps unit=[cm]: January, February, March, April, May, June, July, August, September, October, November, December). Ozone (O3) is taken from GOME and corresponds to mean values of 1996-2000 (maps: January, February, March, April, May, June, July, August, September, October, November, December). The standard deviation of Ozone during the 5 years is shown for 4 months in the following maps: January, April, July, October. Angstroem beta (BE) is calculated with TL and water vapour.
