Annual mean changes\r\n . Seasonal mean changes (DJF, JJA)\r\n \r\n - Precipitation minus evaporation (P–E) climatology (annual mean, 1850-1900).\r\n\r\n---------------------------------------------------\r\n Data provided in relation to figure\r\n ---------------------------------------------------\r\n The map for the annual case (subdir ANN) has two data files :\r\n 1. One for the colored , P-E change, field :\r\n - Fig8-21_ANN_P-E_mean-change_ssp585_ANN_1850-1900_plus3K.nc\r\n \r\n 2. One for the P-E climatology (for red isoline 0) :\r\n - Fig8-21_ANN_P-E_mean_piControl_ANN_1850-1900_.nc. The solid and dashed contours are isolines 0 of that data, masked out over continents. The decision between solid and dashed line is a manual one, based on the latitude of the line. \r\n\r\nThe seasonal panels (subdirs DJF and JJA) have a single file for the colored, P-E change, field.\r\npanel_DJF: Fig8-21_DJF_P-E_mean-change_ssp585_DJF_1850-1900_plus3K.nc\r\npanel_JJA: Fig8-21_JJA_P-E_mean-change_ssp585_JJA_1850-1900_plus3K.nc\r\n\r\nCLARIFICATION: The following file names have been changed from the original, for the purposes of conforming to the file naming standards for the CEDA catalogue. \r\n- panel_ANN: Fig8-21_ANN_P-E_mean-change_ssp585_ANN_1850-1900_+3K.nc ->  Fig8-21_ANN_P-E_mean-change_ssp585_ANN_1850-1900_plus3K.nc\r\n- panel_DJF: Fig8-21_DJF_P-E_mean-change_ssp585_DJF_1850-1900_+3K.nc -> Fig8-21_DJF_P-E_mean-change_ssp585_DJF_1850-1900_plus3K.nc\r\n- panel_JJA: Fig8-21_JJA_P-E_mean-change_ssp585_JJA_1850-1900_+3K.nc -> Fig8-21_JJA_P-E_mean-change_ssp585_JJA_1850-1900_plus3K.nc\r\n\r\nCMIP6 is the sixth phase of the Coupled Model Intercomparison Project.\r\nSSP585 is the Shared Socioeconomic Pathway which represents the upper boundary of radiative forcing and development scenarios, consistent with RCP8.5.\r\n\r\n---------------------------------------------------\r\n Sources of additional information\r\n ---------------------------------------------------\r\n The following weblinks are provided in the Related Documents section of this catalogue record:\r\n - Link to the figure on the IPCC AR6 website\r\n - Link to the report component containing the figure (Chapter 8)\r\n - Link to the Supplementary Material for Chapter 8, which contains details on the input data used in Table 8.SM.1\r\n - Link to the code for all figures in Chapter 8, archived on Zenodo.\r\n - Link to the documentation for CAMMAC, the tool used for AR6 analysis.",
