Atmospheric Density and Pressure profiles were also derived from the EDL accelerometer measurements. In fact, Density is the primary derived quantity. Pressure is derived via vertical integration of the Density, and Temperature is then derived via application of the Ideal Gas Law to the derived Density and Pressure values.
All of these quantities: the derived density, derived pressure, and derived temperature profiles, as well as the 1-σ errors, are provided at 1-kilometer vertical resolution altitude intervals in the PHXCOMPACT.TAB ASCII file in the Raw Data collection.
The data presented above are provided at 1-km altitude increments. The enhanced vertical (and time) resolution data set of derived Entry, Descent, and Landing variables (altitude, density, pressure, temperature) and other relevant measurements is provided in the PHXPROFILES.TAB ASCII data file, which is located within the Reduced Data collection. The contents of PHXCOMPACT.TAB file are derived from the contents of the PHXPROFILE.TAB file as described within the DATASET.CAT file located in the Documents collection.
During the Entry, Descent, and Landing (EDL) phase of the mission, atmospheric data were collected in order to determine the first profiles of atmospheric density, pressure, and temperature from a martian polar region.
