Since landing on Mars in February 2021, Nasa’s Perseverance rover has been collecting data that could help answer crucial questions about Mars and help us better understand also our own home planet. Attached to the rover, a weather station full of advanced technology, including humidity and pressure sensors developed by Finnish Meteorological Institute (FMI) based on Vaisala sensor technology, conduct around-the-clock measurements on temperature, wind speed and direction, pressure, relative humidity, and the size and amount of dust particles.

Designing technology that can withstand a rough landing and remain reliable even in the extreme conditions of Mars is difficult. But even after successful measurements, researchers are faced with an additional challenge: assessing the accuracy of the data.

To ensure best possible data for researchers”, a team at VTT MIKES, the National Metrology Institute of Finland, in cooperation with FMI worked to estimate and reduce uncertainty levels of the measurements.
