Tropospheric Emission Spectrometer

TES is the first satellite instrument to provide simultaneous concentrations of carbon monoxide, ozone, water vapor and methane throughout Earth’s lower atmosphere. This lower atmosphere (the troposphere) is situated between the surface and the height at which aircraft fly, and is an important part of the atmosphere that we often impact with our activities.

TES 作为首个卫星仪器，能够同时提供地球对流层（介于地表与飞机飞行高度之间的重要大气层）中一氧化碳、臭氧、水汽和甲烷的浓度数据。对流层是人类活动频繁影响的大气组成部分。
