2009 TCCON Data Release Auxiliary Files

The Total Carbon Column Observing Network (TCCON) is a network of ground-based Fourier Transform Spectrometers that record direct solar absorption spectra of the atmosphere in the near-infrared. From these spectra, accurate and precise column-averaged abundances of atmospheric constituents including CO2, CH4, N2O, HF, CO, H2O, and HDO, are retrieved. This is the 2009 data release auxiliary files.

全碳柱观测网络（Total Carbon Column Observing Network，TCCON）是一个由地基傅里叶变换光谱仪（Fourier Transform Spectrometers）组成的观测网络，用于记录近红外（near-infrared）波段的大气直接太阳吸收光谱。基于此类光谱，可反演得到包括二氧化碳（CO₂）、甲烷（CH₄）、一氧化二氮（N₂O）、氟化氢（HF）、一氧化碳（CO）、水汽（H₂O）以及氘水（HDO）在内的大气成分的柱平均丰度，且反演结果兼具准确性与精密性。本数据集为2009年数据发布的辅助文件。
