The available code includes Python code for Fig. 2&3 (named "Fig*-code.py") in the main text of the "Tropical mountain ice core 𝜹18O: A Goldilocks indicator for global temperature change". The available data includes original data for Fig.1-Fig.5 (named "Data_Fig*") and post-processed data for analysis in the manuscript "Tropical mountain ice core 𝜹18O: A Goldilocks indicator for global temperature change". The post-processed data includes iTRACE model data, HighRes model data, TES&IASI satellite data, PMIP3&4 data, and GNIP observation data. We thank author Tabor Clay for providing HighRes model simulation data. Contact information: Author Yuntao Bao is responsible for data processing, analysis, calculation, and visualization.
