CosmicDustGroup/cassini-cda-spectra

该数据集包含来自NASA卡西尼号航天器上宇宙尘埃分析仪（CDA）仪器的飞行时间（TOF）质谱数据。CDA旨在分析土星系统和行星际空间中宇宙尘埃粒子的组成。重要提示：由于CDA仪器在2008年10月3日（年日277）后灵敏度下降，该数据集仅包含此日期之前的数据。这一变化发生在卡西尼号飞越土卫二（Enceladus）期间，当时航天器穿过了由土卫二间歇泉喷出的冰粒子云，此事件可能对后续测量引入了偏差。

This dataset contains time-of-flight (TOF) mass spectra from the Cosmic Dust Analyzer (CDA) instrument aboard NASAs Cassini spacecraft. The CDA was designed to analyze the composition of cosmic dust particles in the Saturnian system and interplanetary space. Important: Only data until October 3, 2008 (day of year 277) are included in this dataset. Data recorded after this date are excluded due to a sensitivity drop of the CDA instrument. This sensitivity change occurred after a close flyby of Enceladus, during which Cassini flew through an ice plume—a cloud of ice particles ejected by Enceladus geysers. This event likely introduced bias in subsequent measurements.
