MARS EXPLORATION ROVER POINT-BY-POINT ATMOSPHERIC OPACITY DATA PAGE
Opacity values obtained at 440 nm and 880 nm from Spirit and Opportunity's Pancam imager Solar Images








































   Above are shown point-by-point measured 440 nm and 880 nm Atmospheric Opacity values obtained from Mars Exploration Rover Pancam solar images during Mars Years 26-30 for Spirit and 26-31 (and ongoing) for Opportunity.

   The opacity values plotted above, obtained at 440 nm and 880 nm, are available within the 2tau440_2209_20110214a.tab and 2tau880_2209_20110214a.tab (for Spirit) ASCII files located within the data folder which itself is within the MER Pancam Opacity data archive merao_1xxx. The Opportunity opacity data are located within the 1tau440_2790_20120504a.tab and 1tau880_2790_20120504a.tab ASCII data files located in the same data directory within the MER Pancam Opacity archive merao_1xxx. The contents of these ASCII data files are described in their accompanying **.LBL ('label') files.
