我们提供了一氧化碳（CO）的最低点测量的概述迄今为止获得对流层发射光谱仪（TES）。该仪器是一种高分辨率阵列傅立叶变换光谱仪，用于测量近地轨道红外光谱辐射度。它是2004年7月15日从加州范登堡空军基地成功发射到705千米高度太阳同步轨道上的四个仪器之一。记录了0.06 cm - 1光谱分辨率的最低点光谱，最低点足迹为5 × 8 km。我们描述了用于最低点测量分析的TES检索方法，报告了典型热带和极地海洋位置的平均核，表征了这些位置的随机和系统误差，并描述了仪器性能在CO光谱区域的变化作为时间的函数。从2005年12月和2006年4月的全球调查中获取的对流层中高层CO样本图突出了测量和跟踪全球污染以及从空间确定空气质量的潜力。
We provide an overview of the nadir measurements of carbon monoxide (CO) obtained thus far by the Tropospheric Emission Spectrometer (TES). The instrument is a high resolution array Fourier transform spectrometer designed to measure infrared spectral radiances from low Earth orbit. It is one of four instruments successfully launched onboard the Aura platform into a sun synchronous orbit at an altitude of 705 km on July 15, 2004 from Vandenberg Air Force Base, California. Nadir spectra are recorded at 0.06‐cm−1 spectral resolution with a nadir footprint of 5 × 8 km. We describe the TES retrieval approach for the analysis of the nadir measurements, report averaging kernels for typical tropical and polar ocean locations, characterize random and systematic errors for those locations, and describe instrument performance changes in the CO spectral region as a function of time. Sample maps of retrieved CO for the middle and upper troposphere from global surveys during December 2005 and April 2006 highlight the potential of the results for measurement and tracking of global pollution and determining air quality from space.
