From our experience normal temperature fluctuations do not impact the accuracy. However many NDIR sensors do not like vibrations and get inaccurate after being moved around. Then you need to wait for the automatic baseline calibration to kick in or do a manual calibration. The Aranet 4 uses the Senseair Sunrise that is more resistant to vibrations. However I could imagine that sudden air pressure changes could have an impact on the measurement accuracy.
