Cryosphere Lake Greenhouse Gases Database 2025

This is an expanded cryosphere lake greenhouse gas dataset based on the Cryosphere Inland Water Greenhouse Gases Database (https://doi.org/10.5281/zenodo.11054180). To compile the dataset, we searched various sources, including peer-reviewed papers, dissertations, theses, and public data repositories. The searches were conducted using platforms such as Web of Science, Google Scholar, ProQuest Dissertations & Theses Global, China National Knowledge Infrastructure, Arctic Data Center, Zenodo, Environmental Data Initiative, and PANGAEA. The search string is: (methane OR CH4 OR carbon dioxide OR CO2 OR nitrous oxide OR N2O OR greenhouse*) AND (lake OR pond OR reservoir) AND (Arctic* OR Tibet* OR Greenland OR Antarctic OR glacier* OR permafrost). We ensured completeness by conducting multiple searches before April 2025.The R code used to analyze the temperature dependence of CH4 emissions in cryosphere lakes is available at https://github.com/songchunlin/CryoLakeCH4Temp. The related manuscript by Chunlin Song, Genxu Wang, Cristian Gudasz, R. Iestyn Woolway, Hongyang Chen, Yang Li, and Jan Karlsson is under review by a journal.Correspondence: Chunlin Song ([e-mail]).
