Global Atmospheric Inversions of XCO2 and Solar-Induced Fluorescence (SIF) from OCO-2
Abstract
The OCO-2 satellite was launched on July 2, 2014, to monitor global atmospheric concentration and flux of CO2 from space. We present a novel new atmospheric inversion scheme that solves for respiration and gross primary production (GPP) using a decomposition of multiplicative biases into seasonal harmonics in combination with solar induced fluorescence. Initial CO2 flux results for the time period of September 2014 to March 2016 will be presented with a focus on temporal corrections to the flux and an "in line" bias correction that allows fluxes to be solved for simultaneously with observational bias allowing for a posterior covariance between observational bias and flux errors. Separation of flux terms into mechanistic components then allows comparison to independent estimates such as eddy covariance data and inventory based data such as harvest yields.
