An Error Model for Evaluating the Accuracy of Satellite-Based XCO Products
Vineet Yadav, Jonathan Hobbs, Hai M. Nguyen +8
Several satellites (e.g., OCO-2 & 3) and their derived products now provide spatially extensive coverage of the abundance of carbon dioxide in the atmospheric column (XCO). How…
Low latency global carbon budget reveals a continuous decline of the land carbon sink during the 2023/24 El Nino event
Piyu Ke, Philippe Ciais, Yitong Yao +28
The high growth rate of atmospheric CO2 in 2023 was found to be caused by a severe reduction of the global net land carbon sink. Here we update the global CO2 budget from January 1…
Posterior Uncertainty Estimation via a Monte Carlo Procedure Specialized for Data Assimilation
Michael Stanley, Mikael Kuusela, Brendan Byrne +1
Through the Bayesian lens of data assimilation, uncertainty on model parameters is traditionally quantified through the posterior covariance matrix. However, in modern settings inv…
Global and Brazilian carbon response to El Niño Modoki 2011-2010
K. W. Bowman, J. Liu, A. A. Bloom +8
The El Niño Modoki in 2010 lead to historic droughts in Brazil. We quantify the global and Brazilian carbon response to this event using the NASA Carbon Monitoring System Flux (CMS…
Comparison between Local Ensemble Transform Kalman Filter and PSAS in the NASA finite volume GCM: perfect model experiments
Junjie Liu, Elana Judith Fertig, Hong Li +5
This paper explores the potential of Local Ensemble Transform Kalman Filter (LETKF) by comparing the performance of LETKF with an operational 3D-Var assimilation system, Physical-S…
