Compact and robust instrumentation can monitor the temperature, pressure, and gross composition of the near-surface martian atmosphere. This could place important constraints on the CO2 condensation process (frost versus snow), as well as meteorology at large. Accommodation on a penetrator or hard lander allows delivery in a low-cost or piggyback mission. Measurements proposed include, speed of sound and windspeed and direction via acoustic measurements, total pressure and temperature via conventional means, and possibly CO2 partial pressure measurement by tunable diode laser. Interleaved battery-powered landers are suggested as an alternative to the technical challenges of long-lifetime landers in polar winter. Additional information can be found in the original extended abstract.
