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）是一款地基观测仪器，用于测量地球大气的下行红外辐射。该观测数据拥有宽光谱覆盖范围与足够高的光谱分辨率，可有效区分气体辐射源（如二氧化碳、水汽）与悬浮颗粒物（如气溶胶、水滴及冰晶）。这类天顶式地表观测可用于获取对流层温度与水汽的垂直廓线，同时还可用于测量痕量气体（如臭氧、一氧化碳及甲烷）以及云与气溶胶的下行红外光谱特征。
