| Zusammenfassung |
| Soil respiration – RS, the flux of CO2 from the soil to the
atmosphere – is probably the least well constrained component of the
terrestrial carbon cycle. Here we introduce the SRDB database, a
near-universal compendium of published RS data, and make it available to
the scientific community both as a traditional static archive and as a
dynamic community database that may be updated over time by interested
users. The database encompasses all published studies that report one of the
following data measured in the field (not laboratory): annual RS, mean
seasonal RS, a seasonal or annual partitioning of RS into its
sources fluxes, RS temperature response (Q10), or RS at 10 °C.
Its orientation is thus to seasonal and annual fluxes, not shorter-term
or chamber-specific measurements. To date, data from 818 studies have been
entered into the database, constituting 3379 records. The data span the
measurement years 1961–2007 and are dominated by temperate, well-drained
forests. We briefly examine some aspects of the SRDB data – its climate
space coverage, mean annual RS fluxes and their correlation with other
carbon fluxes, RS variability, temperature sensitivities, and the
partitioning of RS source flux – and suggest some potential lines of
research that could be explored using these data. The SRDB database is
available online in a permanent archive as well as via a project-hosting
repository; the latter source leverages open-source software technologies to
encourage wider participation in the database's future development.
Ultimately, we hope that the updating of, and corrections to, the SRDB will
become a shared project, managed by the users of these data in the
scientific community. |
