Description

Lamont-Doherty Earth Observatory Hybrid Physics Data (LDEO-HPD) Thiscollection contains the Lamont-Doherty Earth Observatory Hybrid Physics Data (LDEO-HPD) product. This product makes near-global monthly estimates of surface ocean pCO2 fromJanuary 1982 through December 2018 with a 1x1 spatial resolution. LDEO-HPD uses aneXtreme Gradient Boosting (XGB) algorithm to make estimates of the misfit between observations and mode-based estimates. These spatiotemporal misfit estimates are then added back to the model-based estimate to make the final LDEO-HPD estimate. This is done for each of nine models part of the Global Carbon Budget 2020. Air-sea CO2 flux is calculated using a bulk parameterization, which is a function of wind speed. Three wind speed products are used to estimate flux. The average across these three estimates is taken as the best estimate.
