14Constraint

Mission

The goal of 14Constraint is to enhance the availability and use of radiocarbon data as constraints for process-based understanding of the age distribution of carbon in and respired by soils and ecosystems. A team of researchers who is envisioned who will (1) work collaboratively with others on building an open community database of 14C data; (2) fill gaps in data and understanding by making new radiocarbon measurements in soil and respired CO2, (3) use models to interpret data for improving models of soil C cycling and (4) produce global data products for comparison with models.
