火星の気象を研究するためには正確なデータが必要 – VTTの解析で測定結果の精度が大幅に向上(Accurate data is needed as researchers study weather on Mars – VTT’s analysis significantly improved accuracy of measurement results)
mage:NASA/JPL-Caltech

VTT の研究者は、NASA の火星ミッションで収集されたデータを、数学を使用してより正確にすることに成功しました。
VTT の誤差補正モデルの結果、相対湿度測定の精度はミッションの要件を大幅に上回りました。
この不確実性の大幅な減少は、世界中の惑星科学者や他の研究者が、火星の大気や水循環から歴史的な居住可能性に至るまでの疑問を研究する際に、この測定データから恩恵を受けることができることを意味します。

Researchers at VTT have succeeded in making data collected on NASA’s Mars mission more accurate by using mathematics. As...

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.
