Atmospheric Emitted Radiance Interferometer (AERI): channel 2 data - aerich2

The atmospheric emitted radiance interferometer (AERI) is a ground-based instrument that measures the downwelling infrared radiance from the Earth s atmosphere. The observations have broad spectral content and sufficient spectral resolution to discriminate among gaseous emitters (e.g., carbon dioxide and water vapor) and suspended matter (e.g., aerosols, water droplets, and ice crystals). These upward-looking surface observations can be used to obtain vertical profiles of tropospheric temperature and water vapor, as well as measurements of trace gases (e.g., ozone, carbon monoxide, and methane) and downwelling infrared spectral signatures of clouds and aerosols.

大气发射辐射干涉仪（Atmospheric Emitted Radiance Interferometer, AERI）是一种地基观测仪器，可测量地球大气的下行红外辐射。该观测数据拥有宽泛的光谱覆盖范围与充足的光谱分辨率，能够区分各类气体辐射源（如二氧化碳与水蒸气）及悬浮颗粒物（如气溶胶、水滴与冰晶）。这类地面天顶观测可用于获取对流层温度与水蒸气的垂直廓线，同时还可实现痕量气体（如臭氧、一氧化碳与甲烷）的测量，并能获取云与气溶胶的下行红外光谱特征。
