The ORNL DAAC recently released the following new Carbon Monitoring System (CMS) datasets by Haynes, K.D., et al. (2021):

SiB4 Modeled Global 0.5-Degree Hourly Carbon Fluxes and Productivity, 2000-2018

SiB4 Modeled Global 0.5-Degree Daily Carbon Fluxes and Pools, 2000-2018

SiB4 Modeled Global 0.5-Degree Monthly Carbon Fluxes and Pools, 2000-2018

These datasets provide global terrestrial carbon cycle model outputs predicted by the Simple Biosphere Model, Version 4.2 (SiB4), at a 0.5-degree spatial resolution covering the time period 2000 through 2018. SiB4 is a mechanistic land surface model that integrates heterogeneous land cover, environmentally responsive phenology, dynamic carbon allocation, and cascading carbon pools from live biomass to surface litter to soil organic matter. The SiB4 output is per plant functional type (PFT) within each 0.5-degree grid cell. 

The three datasets differ by frequency of model data output and aggregation and provide data at hourly, daily, and monthly time steps.

The NASA CMS program is designed to make significant contributions in characterizing, quantifying, understanding, and predicting the evolution of global carbon sources and sinks through improved monitoring of carbon stocks and fluxes. The System uses NASA satellite observations and modeling/analysis capabilities to establish the accuracy, quantitative uncertainties, and utility of products for supporting national and international policy, regulatory, and management activities. CMS data products are designed to inform near-term policy development and planning.

Additional data from CMS and other relevant links can be found on the ORNL DAAC's CMS Project Page.
