Based on a peak-over-threshold (99.7%) method applied to the historical extreme still water levels of Global Extreme Sea Level Analysis version 2 (GESLA2) following Special Report on Ocean and Cryosphere in a Changing Climate (SROCC) and additionally fitting a Gumbel distribution between Mean Higher High Water (MHHW) and the threshold following Buchanan et al. (2016), using the regional sea level projections of Section 9.6.3.3 for (a-f).\r\n\r\n Further details on data sources and processing are available in the chapter data table \r\n(Table 9.SM.9).\r\n\r\n---------------------------------------------------\r\n Data provided in relation to figure\r\n ---------------------------------------------------\r\n Data provided in relation to Figure 9.32\r\n \r\n - Data file: Fig9-32a_facts_esl_af_allow_ssp585_2050.nc\r\n - Data file: Fig9-32b_facts_esl_af_allow_ssp585_2100.nc\r\n - Data file: Fig9-32c_facts_esl_af_allow_ssp245_2050.nc\r\n - Data file: Fig9-32d_facts_esl_af_allow_ssp245_2100.nc\r\n - Data file: Fig9-32e_facts_esl_af_allow_ssp126_2050.nc\r\n - Data file: Fig9-32f_facts_esl_af_allow_ssp126_2100.nc\r\n\r\nPython file 'facts_esl_output_to_NetCDF.py' included in the 'Plotted Data' folder of the dedicated GitHub repository is not archived here but on Zenodo at the link provided in the Related Documents section of this catalogue record.
