Tan-Tracker global daily NEE and ocean carbon fluxes for 2015-2019 (TT2021 dataset)

Tan-Tracker global daily NEE and ocean carbon fluxes for 2015-2019 (TT2021 dataset)


Here we present a global and regional resolved terrestrial ecosystem carbon flux (NEE) as well as ocean carbon flux dataset from 2015 to 2019, inclusive. The dataset is generated using the Tan-Tracker inversion system by assimilating Observing Carbon Observatory 2 (OCO-2) column CO2 retrievals. Apart from optimized NEE and ocean fluxes, CO2 emissions from other sectors (e.g. fossil fuel emissions, biomass burning emissions, chemical sources) are also included to help calculate the carbon budget. The atmospheric transport model used is GEOS-Chem, model simulated CO2 concentrations driven by posterior fluxes are provided as well. We still contain a tabular summary about the annual global carbon budget, annual and monthly NEE and ocean fluxes with corresponding uncertainties. The posterior fluxes are comprehensively validated by comparing the posterior simulated CO2 concentrations with OCO-2 independent retrievals and Total Carbon Column Observing Network (TCCON) measurements. The validation shows that the posterior carbon fluxes could significantly improve the modelling of atmospheric CO2 concentrations, with global mean bias of 0.33 ppm against OCO-2 retrievals and 0.12 ppm against TCCON measurements. The dataset has been applied to evaluate the global, TransCom regional, and Tibetan Plateau carbon fluxes. We plan to update the dataset annually in the future, aiming to better understand the global carbon cycle, support the formulation of climate policies , and project future climate change.

数据使用方法

File naming: The carbon flux data and CO2 concentration data are stored in NetCDF format. The name of the carbon flux file is "TT2021.Flux.yyyymmdd.nc", and the name of the CO2 concentration file is "TT2021.CO2.yyyymmdd.nc", where yyyy represents the year ,mm represents the month, and dd represents the day. For example, TT2021.Flux.20150101.nc represents the NetCDF file describing the global carbon fluxes on January 1, 2015

Data reading method: All the NetCDF files in this dataset can be opened directly with programs like Panoply and Ncview.
