title: Dataset: First comprehensive assessment of industrial-era land heat uptake from multiple sources

description: Dataset Overview

This Zenodo repository contains a comprehensive dataset of global mean yearly land heat uptake (LHU) estimates for the historical period (all data sources) and the SSP585 scenario (exclusively for CMIP6 models). The dataset includes estimates from multiple data sources: gridded observations (OBS, 5 sources), reanalyses (REA, 7 sources), and CMIP6 simulations (CMIP6, 37 models). These LHU estimates were developed and first analyzed in García-Pereira et al. (2024).

The estimates were obtained using the one-dimensional heat conduction forward model (ConForM; García-Pereira et al., 2023), forced with yearly global mean ground surface temperature data from each source over various time periods. The time periods include the full available range (fromINIT), as well as specific periods starting in 1950, 1960, and 1971, extending to the most recent data available. For a detailed explanation of the methods, rationale, main findings, and comparisons with previous geothermal LHU estimates, refer to García-Pereira et al. (2024).

Dataset Contents

The dataset is provided in NetCDF format and is organized by data source type (OBS, REA, CMIP6) and time period (fromINIT, from1950, from1960, from1971). Each file follows the naming convention:



<source_type>_LHU_ym_gb_sum_<period>.nc


where <source_type> indicates the data source (OBS, REA, CMIP6) and <period> specifies the starting time (fromINIT, from1950, from1960, from1971). For example, OBS_LHU_ym_gb_sum_from1971.nc contains LHU estimates derived from observational data starting in 1971. For files corresponding to from1950, from1960, and from1971, the dataset also includes mean and standard deviation calculations. Additionally, raw LHU estimates derived from CMIP6 subsurface temperature data are provided in the file CMIP6/CMIP6raw_LHU_ym_gb_sum.nc.
