A 31 March 2022 news item, Mars more volcanically active than we thought, marsquakes hidden in NASA Insight data suggest, states that in relation to measuring of seismic data,
A major source of noise comes from gusty winds, which pick up when the Sun warms the atmosphere and die down again about an hour before the Sun sets.
For this reason, most marsquakes have been detected during the quieter night and pre-sunset time, when the minute waveforms generated by small quakes aren't lost in the noise.
A NASA website concerning the instrumentation of the Mars Insight probe, states,
A suite of wind, pressure, temperature, and magnetic field sensors help fine-tune the seismometer's measurements. This helps it sense surface vibrations generated by weather systems such as dust storms, or by turbulence in the atmosphere due to phenomena such as dust devils, which can also generate seismic waves.
It appears Insight does not have a dedicated light detection device, which would be useful in determining whether the seismometer is measuring ground vibrations during the day or during the night time?
Output from the solar panels could easily provide this data. Are the solar panels used in this way and if not how do scientists know when it is day time or night?
