See description on <a href="https://www.cen.uni-hamburg.de/en/icdc/data/cryosphere/cmip6-sea-ice-area.html">https://www.cen.uni-hamburg.de/en/icdc/data/cryosphere/cmip6-sea-ice-area.html</a> about how SIA is derived. See <a href="https://www.cen.uni-hamburg.de/en/icdc/data/cryosphere/cmip6-sea-ice-area.html">https://www.cen.uni-hamburg.de/en/icdc/data/cryosphere/cmip6-sea-ice-area.html</a> to learn about the models included into this CMIP6 archive. SIA time series are provided for historical, piControl,and ssp runs (119, 126, 245, 370, 460, 585). The number of time series provided per run depends on the CMIP6 model; it might be zero.
