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…
