TCCON data from Eureka (CA), Release GGG2020.R0

<p>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 GGG2020 data release of observations from the TCCON station at Eureka, Canada</p>

全碳柱观测网络（Total Carbon Column Observing Network, TCCON）是由地基傅里叶变换光谱仪组成的观测网络，可记录近红外波段下大气的直接太阳吸收光谱。基于此类光谱数据，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（H₂O）以及氘化氢（HDO）在内的多种大气组分的高精度、高准确度柱平均丰度。本数据集为加拿大尤里卡站点TCCON观测数据的GGG2020版本发布成果。
