摘要：The magnitude of carbon (C) loss to the atmosphere via microbialdecomposition is a function of the amount of C stored in soils, the qualityof the organic matter, and physical, chemical, and biological factors thatcomprise the environment for decomposition. The decomposability of C iscommonly assessed by laboratory soil incubation studies that measuregreenhouse gases mineralized from soils under controlled conditions. Here,we introduce the Soil Incubation Database (SIDb) version 1.0, a compilationof time series data from incubations, structured into a new, publiclyavailable, open-access database of C flux (carbon dioxide, CO2, ormethane, CH4). In addition, the SIDb project also provides a platformfor the development of tools for reading and analysis of incubation data aswell as documentation for future use and development. In addition tointroducing SIDb, we provide reporting guidance for database entry and therequired variables that incubation studies need at minimum to be included inSIDb. A key application of this synthesis effort is to better characterizesoil C processes in Earth system models, which will in turn reduce ouruncertainty in predicting the response of soil C decomposition to a changingclimate. We demonstrate a framework to fit curves to a number of incubationstudies from diverse ecosystems, depths, and organic matter content using abuilt-in model development module that integrates SIDb with the existingSoilR package to estimate soil C pools from time series data. The databasewill help bridge the gap between point location measurements, which arecommonly used in incubation studies, and global remote-sensed data or dataproducts derived from models aimed at assessing global-scale rates ofdecomposition and C turnover. The SIDb version 1.0 is archived and publiclyavailable at https://doi.org/10.5281/zenodo.3871263 (Sierra et al., 2020), and the database is managedunder a version-controlled system and centrally stored in GitHub (https://github.com/SoilBGC-Datashare/sidb, last access: 26 June 2020).
