2021年5月26日 · We present the first results from the application of the Fast atmOspheric traCe gAs retrievaL (FOCAL) algorithm to derive column-averaged dry-air mole fractions of carbon dioxide (XCO2) from GOSAT and GOSAT-2 radiances and their validation.

2022年1月31日 · After quality filtering and bias correction, the differences in XCO2 between ACOS GOSAT v9 and both TCCON and models have a scatter (1σ) of approximately 1 ppm …

中国地区大气CO2浓度对全球气候变化有重要的影响。 本文基于日本GOSAT卫星短波红外CO2的长期观测数据，对2010年—2016年中国大陆上空CO2浓度的分布特征和变化趋势进行分析研究。

2018年10月7日 · 日本宇宙航空开发研究机构 (Japan Aerospace Exploration Agency)于2009年发射了全球第一颗温室气体探测卫星GOSAT，星上搭载高光谱傅里叶变换光谱仪 (Fourier Transformation Spectrometer, FTS)对全球大气CO 2 浓度进行高光谱遥感探测 (Kuze et al，2009)。 卫星遥感可以提供稳定、长时间序列、广空间区域的大气成分信息 (张兴赢等，2007)，应用卫星遥感数据来分析全球大气CO 2 的变化趋势已有非常广泛的应用 (白文广 …

2023年8月10日 · Moreover, the fused results present coincident spatial patterns with GOSAT and OCO-2, which accurately display the long-term and seasonal changes in globally distributed XCO2 and XCH4. The daily global seamless gridded (0.25∘) XCO2 and XCH4 from 2010 to 2020 can be freely accessed at https://doi.org/10.5281/zenodo.7388893 (Wang et al., 2022a).

This study is the first to validate the XCO2 of satellite observations with total carbon column observing network (TCCON) data and to compare the global XCO2 distribution for the passive satellites Orbiting Carbon Observatory-2 (OCO-2) and Greenhouse Gases Observing Satellite (GOSAT), which are on-orbit greenhouse gas satellites.

2022年2月20日 · In this paper, we mapped a global spatiotemporally continuous XCO 2 dataset (Mapping-XCO 2) using the XCO 2 retrievals from GOSAT and OCO-2 during the period from …

2021年2月10日 · In this study, in order to assimilate the GOSAT (Greenhouse Gases Observing Satellite) XCO2 retrievals, the Global Carbon Assimilation System (GCAS) is upgraded with new assimilation algorithms, procedures, a localization scheme, …

2022年5月31日 · In this study, we apply an empirical orthogonal function (EOF)-based method on the GOSAT L3 products (137 images, from January 2010 to May 2021) to estimate the column average of carbon dioxide and methane (XCO2–XCH4) within the entire Earth.

2024年4月13日 · We designed an ML model to predict ΔXCO 2 (OCO-2–GOSAT) using a training data set from 2014 to 2020, with 71 predictors (Table S3 in Supporting Information S1) extracted from the GOSAT Level 2 product, such as band spectra, …
