C C C 1 97.196 1.02 1.2 176 7.71 -108.90 -78.28 C ============================================================= C C A "C" or other character in column 1 indicates that the row C contains text or other, information. C Column 2 is reserved for special flags which can be: C data quality indicators for a row with problems; C an indicator to reject one or more variables in C the row, e.g., wind is bad but pressure and temperature C are good, etc. C These will be defined as necessary. C C Rows will not be blank; there will always be at least a "C" in C column 1 C C Column 3 is always blank. C C Definitions C =========== C C Year Mars year, approximately 687 Earth days C Solar Longitude, Angular direction from Mars to the Sun C L_s; 0 to 360 degrees C Deg. 90 = summer, 180 = autumn, 270 = winter C 0 or 360 = spring in northern hemisphere C Sol Martian days after landing; 1 sol is C Viking landed on sol 0 C One sol is 24.62 hours C Wind speed Meters per second C Wind direction Degrees, (direction from which the C wind blows) C Pressure mb = millibars, 1 mb = 100 hPa, where C hPa = hecta Pascals C Temperature Degrees; C = Centigrade; F = Fahrenheit C C ================================================================= C C These rows of data are formed by checking for bad data, C removing or reprocessing them, collecting the points into one C of 25 equal length intervals, "bins", in each sol, and then C averaging each bin. When no data exist in one to a few bins, C a value is interpolated, ( using a cubic spline technique,, C which is not described here.)
