"Hourly" Averaged Surface Meteorology Data
                       July 20, 1976 Ls 96.8 MY 12 to Aug 18, 1979 Ls 341.4 MY 13


























         The Viking 1 Meteorology Boom, on which were located the wind speed and direction sensors
         and the Ambient and Reference temperature sensors











    The above plot shows data obtained during a 20-sol interval of the Viking Lander 1 mission during which the 1977b global dust storm developed are shown on the plot above. Each 'bin' spans 1/25th of a martian sol, and thus represents a bit less than one hour of data.

    Data

    Hourly-averaged Surface meteorology data (pressure, temperature, wind speed and direction), sols 1-350 - dataset VL1/VL2-M-LCS-5-ATMOS-OPTICAL-DEPTH-v1.0 This dataset contains binned and splined data obtained from the Viking Meteorology Instrument System (VMIS) through portions of the Viking Lander 1 mission. The dataset consists of mean values of pressure, temperature, and wind speed (zonal and meridional) calculated for 25 bins of equal duration per day.

    Hourly-averaged Surface meteorology data (pressure, temperature, wind speed and direction) - dataset VL1/VL2-M-MET-4-BINNED-P-T-V-v1.0 This dataset contains binned and splined data obtained from the Viking Meteorology Instrument System (VMIS) through most of the Viking Lander 2 mission sols 1-1050 and the early days of the Lander 1 mission. The dataset consists of mean values of pressure, temperature, and wind speed (zonal, meridional, and combined) and relevant statistics and warning flags calculated for 25 bins of equal duration per day.
