MAVEN (Multiple Instrument Ensemble) In-situ Observations, Data Product Bundle, Key Parameter (KP), 4 s Data

The MAVEN In-situ Calibrated Level 2, L2, Science Data Bundle contains selected fully calibrated Data from the Neutral Gas and Ion Mass Spectrometer, NGIMS, Instrument and the Particles and Fields Package together with Ephemeris Information. The Particle and Fields In-situ Instrument Data are from the Extreme Ultraviolet, EUV, Langmuir Probe and Waves, LPW, Antenna, Magnetometer, MAG, Solar Energetic Particles, SEP, SupraThermal And Thermal Ion Composition, STATIC, Solar Wind Electron Analyzer, SWEA, and Solar Wind Ion Analyzer, SWIA, Instruments. All of these Data are in Physical Units and are averaged and/or sampled at a uniform 4 s Cadence. These In-situ Data are derived directly from the Level 2 Data. The Ephemeris Data are derived by using SPICE Libraries and Kernels provided by MAVEN Navigation, NAV, Team and Lockheed-Martin.

MAVEN原位校准2级（Level 2, L2）科学数据包包含选自中性气体与离子质谱仪（Neutral Gas and Ion Mass Spectrometer, NGIMS）、粒子与场包的全校准数据，以及星历信息。其中粒子与场原位仪器数据来自极紫外（Extreme Ultraviolet, EUV）、朗缪尔探针与波（Langmuir Probe and Waves, LPW）天线、磁强计（Magnetometer, MAG）、太阳高能粒子（Solar Energetic Particles, SEP）、超热与热离子成分分析仪（SupraThermal And Thermal Ion Composition, STATIC）、太阳风电子分析仪（Solar Wind Electron Analyzer, SWEA）以及太阳风离子分析仪（Solar Wind Ion Analyzer, SWIA）等仪器。所有此类数据均采用物理单位（Physical Units）表征，并以统一的4秒采样周期（Cadence）进行平均处理和/或采样。这些原位数据直接源自2级（Level 2）原始数据。星历数据通过使用MAVEN导航团队（MAVEN Navigation, NAV）与洛克希德·马丁（Lockheed-Martin）提供的SPICE库（SPICE Libraries）及内核（Kernels）生成。
