This study presents a novel method for generating long-term (&gt;1000 years) site-specific climate data to drive peatland ecohydrological models. Using meteorological observations, we employ the Long Ashton Research Station Weather Generator (LARS-WG) to produce stochastic climate series for precipitation and temperature. The method integrates Holocene climate reconstructions from the EPOCH-2 database to simulate paleoclimate trends and interpolates climate projections based on Shared Socioeconomic Pathways (SSP) from CMIP6 models. Finally, a time series of potential evapotranspiration is calculated using a modified version of the Thornthwaite equation. This approach ensures continuity in climate inputs for peatland modelling, aiding in the assessment of long-term climate impacts on carbon dynamics. Our method provides a replicable framework for other regions, supporting improved climate-driven peatland simulations.<ul><li><span>•</span><span><div>Long-term paleoclimate data with climate projections tailored to specific sites are scarcely available</div></span></li><li><span>•</span><span><div>This research outlines a simple method for generating climate series for driving ecosystem models</div></span></li><li><span>•</span><span><div>Uses open-source resources and databases that are applicable across Europe</div></span></li></ul></div></div>","PeriodicalId":18446,"journal":{"name":"MethodsX","volume":"14 ","pages":"Article 103265"},"PeriodicalIF":1.6,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143714992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional disciplinary research approaches have well-established evaluation criteria and processes in which research quality is often narrowly defined.

Standard research assessment criteria are simply inadequate for TDR, and inappropriate use of standard criteria may disadvantage TDR proposals and impede the development of TDR. This paper presents a Quality Assessment Framework (QAF) designed for TDR, along with guidance for its application.
