NOAA GOES-R Series Space Environment In-Situ Suite (SEISS) Instrument Calibration Data

The Space Environment In-Situ Suite (SEISS) is comprised of four sensors that monitor proton, electron, and heavy ion fluxes in the magnetosphere. These four sensors are the Energetic Heavy Ion Sensor (EHIS), the Magnetospheric Particle Sensors - High and Low (MPS-HI and MPS-LO), and the Solar and Galactic Proton Sensor (SGPS). There are two SGPS units on each satellite, one looking westward and one looking eastward. The SEISS instrument is critical in assessing the risk for electrostatic discharge and radiation hazards to satellites and astronauts. The information collected by SEISS can also be used to warn of high flux events that may damage radio communication. The SEISS Calibration Data file contains data used to support the generation of EHIS, MPS-LO, MPS-HI, and SGPS Level 1b products, and monitor and evaluate the health and performance of the sensor suite. This
file contains derived level 1b calibration parameters including raw sensor count rates, valid raw sensor
count data percentages, and dead-time and contamination correction factors needed for the production of
all the SEISS products. The Instrument Calibration Data product contains the data needed to evaluate, monitor, and trend sensor performance.

空间环境原位套件（Space Environment In-Situ Suite，SEISS）由四款传感器组成，用于监测磁层中的质子、电子及重离子通量。该套件搭载的四款传感器分别为高能重离子探测器（Energetic Heavy Ion Sensor，EHIS）、磁层粒子高低能探测器（Magnetospheric Particle Sensors - High and Low，MPS-HI与MPS-LO）以及太阳与银河质子探测器（Solar and Galactic Proton Sensor，SGPS）。每颗卫星配备两台SGPS设备，一台朝西观测，另一台朝东观测。
SEISS仪器对评估卫星与航天员面临的静电放电及辐射危害风险具有关键作用。SEISS采集的观测数据还可用于预警可能损毁无线电通信的高通量事件。
SEISS校准数据文件包含用于生成EHIS、MPS-LO、MPS-HI及SGPS的1b级（Level 1b）产品，并监测、评估整套传感器健康与性能的数据。该文件包含衍生的1b级校准参数，包括原始传感器计数率、有效原始传感器计数数据占比，以及生成所有SEISS产品所需的死时间与污染校正因子。
仪器校准数据产品包含用于评估、监测及追踪传感器性能趋势的数据。
