Soil respiration database

Soil respiration (Rs) in situ measurements that were reported in peer-reviewed publications were collected into a database. The database contains annual Rs flux, share of autotrophic Rs, climate parameters, type of soil and vegetation. 3822 records on Rs fluxes around the globe were collected from 932 studies, spanning the measurement years 1961-2011. The largest portion of data was taken from the global database by Bond-Lamberty and Thomson (2014, 2018). We have taken from this database only the records where annual Rs flux or mean seasonal rate of Rs or root contribution to the Rs were reported. Data from additional 290 sources were collected on the same basis, from the northern hemisphere, with a special focus on Russia. The regions most frequently represented are Northern America (n=1835), Europe (n=1116) and Asia (n=872). Data from temperate ecosystems dominate in the database (n=1816), boreal zone is represented by 911 records, subtropical and tropical biomes are represented by 628 and 400 records accordingly. The most data collected in forests (n=2475), grasslands (n=518) or arable land (n=517).
