VIKING LANDER POINT-BY-POINT ATMOSPHERIC OPACITY DATA PAGE
Viking Lander 1 Atmospheric Opacity Data Viking Lander 2 Atmospheric Opacity Data










Above are shown point-by-point measured Atmospheric Opacity measurements obtained by the Viking Landers during Mission Years 1 and 2, spanning sols 6-920 at VL1 and 6-872 at VL2.
The 0.67 μm Opacity values plotted above are available within the vl_opac.dat ASCII file located within the data folder which itself is within the Viking Lander data archive vl_1001. The contents of the vl_opac.dat file and a description of the structure of that file are available in the vl_opac.lbl file which is also located within the data folder within the data archive vl_1001. The VL2 point-by-point optical depth values follow the VL1 optical values within the vl_opac.dat file.
