论文摘要
使用从Tirvim傅立叶光谱仪获得的NADIR观察结果（ACS）在Exomars Trace Gas Orbiter（TGO）上获得的一部分，使用Tirvim傅立叶谱仪（ACS）获得的NADIR观察结果来分析火星大气中的热潮。该数据是在北夏季冬至附近的太阳经度（LS）75°-105°（MY）35°。观察结果具有完整的当地时间覆盖范围，这可以分析每日温度异常。与LMD MARS通用循环模型（GCM）相比，观察到的区域平均温度在〜100Pa时降低4-6K，但朝夏极较高。波模式的分解显示出主要的昼夜潮汐和重要的半日间潮汐和昼夜开尔文波，最大振幅分别为5K，3K和2.5K，从数十到数百个PA。结果总体上与LMD MARS GCM良好，但与LMD MARS相当良好，但明显的早期（〜1h）（〜1H）和SEMI（〜1H）〜1H）和〜1houral（〜1H）〜1H〜HISI 〜1H〜HISI 〜ININIS〜HINIENIEN（〜1H）。
Thermal tides in the Martian atmosphere are analyzed using temperature profiles retrieved from nadir observations obtained by the TIRVIM Fourier-spectrometer, part of the Atmospheric Chemistry Suite (ACS) onboard the ExoMars Trace Gas Orbiter (TGO). The data is selected near the northern summer solstice at solar longitude (LS) 75°-105° of Martian Year (MY) 35. The observations have a full local time coverage, which enables analyses of daily temperature anomalies. The observed zonal mean temperature is lower by 4-6K at ~100Pa, but higher towards the summer pole, compared to the LMD Mars General Circulation Model (GCM). Wave mode decomposition shows dominant diurnal tide and important semi-diurnal tide and diurnal Kelvin wave, with maximal amplitudes of 5K, 3K, and 2.5K, respectively, from tens to hundreds of Pa. The results generally agree well with the LMD Mars GCM, but with noticeable earlier phases of diurnal (~1h) and semi-diurnal (~3h) tides.
