δ18Op decomposition dataset based on a preindustrial (PI) iCAM5.3 water-tagging experiment

TS_month_model.ncSimulated monthly climatological surface temperature for the pre-industrial period. TS_month_observation.ncObserved monthly climatological surface temperature derived from the CRU dataset (https://crudata.uea.ac.uk/cru/data/hrg/). d18Op_month_model.ncSimulated monthly climatological d18Op for the pre-industrial period. d18Op_month_observation.csvPost-processed observational monthly d18Op data derived from the Global Network of Isotopes in Precipitation (GNIP) database (https://nucleus.iaea.org/wiser). data_d18Op_decomposition.rarDecomposition results of the simulated pre-industrial d18Op seasonal cycle. These files are used to quantify the relative contributions of different processes to the total d18Op seasonal variability.
