The data descriptions for Viking Lander 1 Hourly-averaged Vl1 Surface meteorology data
(pressure, temperature, wind speed and direction - sols 1-350) and Viking lander 1 & 2 Hourly-averaged Surface meteorology data
(pressure, temperature, wind speed and direction - Viking Lander 2 mission sols 1-1050 and sols 1-40 of the Lander 1 mission) describe these dataset that contain binned and splined data obtained from the Viking Meteorology Instrument System (VMIS). The datasets consist 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 sol.
Retrieving the Data Volume
Within the data volume
the Viking 1 data file and labels are identified as vl_mbin.dat
respectively while the data file and labels for the combined Viking 1 and 2 data are identified as vl_tbin.dat, vl_tbin.xml and vl_tbin.lbl respectively.
