20-Year Synthesis of Soil Respiration Data at Harvard Forest 1991-2008

All data on soil carbon flux (“soil respiration”) collected using chamber-based methods at Harvard Forest from a range of observational and experimental plots were collated, their units were harmonized, and geographic (locations) and environmental characteristics (soil series, drainage class, soil temperature, soil moisture, vegetation type, etc.) were identified for each observation. This yielded a dataset with 106,192 observations of soil respiration taken between 1991 and 2008. These data provide a unique resource for exploring spatial and temporal patterns in soil respiration in a range of common New England forest types. For the Giasson, et al. (2013) publication, we also used 24 site-years of eddy covariance measurements from two Harvard Forest sites (EMS and Hemlock towers) to examine the relationship between soil and ecosystem respiration. Here, we present all derived/synthetic datasets associated with the manuscript. M.-A. Giasson, A. M. Ellison, R. D. Bowden, P. M. Crill, E. A. Davidson, J. E. Drake, S. D. Frey, J. L. Hadley, M.
