迈克尔逊全球高分辨率热层成像干涉仪(MIGHTi)于2019年10月搭载美国国家航空航天局(NASA)的电离层连接(ICON)探测器卫星发射，用于测量中上层和热层下部(MLT)边缘的风和温度。温度是利用分子氧大气波段从白天90-127公里高度和夜间90-108公里高度的763纳米附近观测到的。在这里，我们描述了温度恢复的测量方法和方法，包括允许更好地了解仪器响应的独特的在轨操作。MIGHTi温度测量方法的不同之处在于来自两个不同传感器的同时观测，允许两个自洽的温度产品。我们将MIGHTi温度与现有的MLT空间和地面观测结果进行了比较。MIGHTi的温度在昼夜90-95公里的范围内，与这些观测结果的平均温度在7K以内。在白天平均99-105公里处，MIGHTi温度比NASA定时卫星上使用宽带发射辐射测量仪(SABER)探测大气的一致观测高18K。由于MIGHTi和SABER观测之间的差异在给定高度下主要是恒定的偏差，因此基于温度变化的科学分析结论在很大程度上不受影响。
The Michelson Interferometer for Global High-resolution Thermospheric Imaging (MIGHTI) was launched aboard NASA’s Ionospheric Connection (ICON) Explorer satellite in October 2019 to measure winds and temperatures on the limb in the upper mesosphere and lower thermosphere (MLT). Temperatures are observed using the molecular oxygen atmospheric band near 763 nm from 90–127 km altitude in the daytime and 90–108 km in the nighttime. Here we describe the measurement approach and methodology of the temperature retrieval, including unique on-orbit operations that allow for a better understanding of the instrument response. The MIGHTI measurement approach for temperatures is distinguished by concurrent observations from two different sensors, allowing for two self-consistent temperature products. We compare the MIGHTI temperatures against existing MLT space-borne and ground-based observations. The MIGHTI temperatures are within 7 K of these observations on average from 90–95 km throughout the day and night. In the daytime on average from 99–105 km, MIGHTI temperatures are higher than coincident observations by the Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) instrument on NASA’s TIMED satellite by 18 K. Because the difference between the MIGHTI and SABER observations is predominantly a constant bias at a given altitude, conclusions of scientific analyses that are based on temperature variations are largely unaffected.
