mbar

Atmospheric air pressure is often expressed in millibars and sea level atmospheric air pressure is defined as 1013.25 mbar which is equivalent to 1 atm.

Why does the troposphere pressure greater than 200 mbar get colder as altitude increases?

The atmospheric pressure measured at the two Viking sites varied over a Martian year between 7 and 10 millibars 1 bar is Earth sea-level atmospheric pressure, or 14.7 psi; 10 millibar, or mbar, is 1 percent Earth sea-level atmospheric pressure, with a year-round average of about 8 mbar observed at the higher altitude Viking 1 landing site on Chryse Planitia.

However, if the polar temperature should rise to a point where the vapor pressure is much greater than that which can be produced by the mass in the cap reservoir between 50 and 100 mbar then the cap will disappear and the atmosphere will be regulated by the regolith reservoir.
