TY - Data T1 - Pan-Arctic Free Excess Ice and its Melting CH4 Emission Sensitivity Coupled Simulation Test Data Set (1995-2014) A1 - zhu jia wen A1 - dong xiao DO - 10.12072/ncdc.db7707.2026 PY - 2026 DA - 2026-08-31 PB - National Cryosphere Desert Data Center AB - Data sets related to the results of "Rapid melting of permafrost/key processes affecting climate in the Pan-Arctic region and future changes in typical climate-ecology-environment elements"(1 set of coupled sensitivity experiments), the models used include the Earth System Model CAS-ESM of the China Academy of Sciences. The temporal resolution of the test data is monthly average, the spatial resolution is 1.4 degrees for atmospheric land surface variables, and the ocean sea ice variables is 1 degree for ocean sea ice variables. The spatial range is north of the pan-Arctic (50N north latitude). The test is set up with the same hist test but there is no excess ice and its melted CH4 emissions. The operation period is 1980-2014, and the first 15 years are used as spin-up. Data is available for the last 20 years. Data elements: Historical simulation experiments of CAS-ESM model, variables include surface temperature tas, precipitation pr, relative humidity hurs, surface wind speed sfcWind, total primary productivity gpp, carbon dioxide co2, cLitter, cSoil, cVeg, fire carbon emission fFire, vegetation leaf area index lai, mrro, mrros, pfrost, ra, rh, sea ice concentration siconc, sea ice thickness sithick, ua, va, zg, pfrost, alt.
