Spin-up
Was A Spin-Up Performed?: Yes
Spin-Up Design: 5000 years of PNV spin-up, followed by 161 years of land-use spin-up. Both spin-ups recycle 200 years of piControl climate data and use a constant CO2 concentration of 286.23 ppm (value for 1860). The land-use spin-up uses transient land-use patterns from the period 1700-1860.
Natural Vegetation
Natural Vegetation Partition: dynamic vegetation distribution
Management & Adaptation Measures
Management: crop sowing dates computed internally but fixed after 1960 in biome, permafrost and water sector runs

Spin-up
Was A Spin-Up Performed?: Yes
Spin-Up Design: 5000 years of PNV spin-up, followed by 390 years of land-use spin-up, both recycling 120-year random climate sequence (taken from 1901-1930), spin-up leads into transient run 1901 - end of climate dataset; 278 ppm CO2 used before 1765, after 1765 CO2 from provided input file
