Survey results, data for "Revisiting the Global Methane Cycle Through Expert Opinion"

We developed the written survey questions using the Qualtrics Survey Tool with an enterprise license held by Yale University. We interactively revised background information, response formats, and survey questions based on our discussion with leading scientists in uncertainty quantification and expert opinion analyses. Survey respondents did not include experts involved in survey development or testing. From July to August 2021, the survey questions were further refined for readability, clarity, and scientific rigor following a pilot interview with several early-career scientists.All authors involved in the development of the survey completed human subjects’ protection training offered at Yale University. The survey was approved by the Yale University Institutional Review Board (Yale IRB) and included a risk statement as follows: “You will not directly benefit from participation in this research study, but we hope that the input we receive from all our experts will advance public policy in this area. Your responses will not be linked to your name. Your participation in this study is completely voluntary and the limited amount of personal information collected will be dissociated with your answers prior to data analysis. We are required to inform you that the only risk the Yale IRB review has identified is a possible loss of confidentiality of your answers.”The survey was finally distributed to experts through emails on 19 August 2021 with an accessible link and closed on 31 December 2021. To better help survey participants access all information and questions while filling out the survey, we also distributed a pdf document containing the questionnaires (Supplementary information). The final survey consists of three sections: Introduction, Pre-survey, and the Main Questionnaire containing 16 questions related to uncertainties in the global methane budget. The questionnaire includes a mix of quantitative survey questions to answer initial research and qualitative survey questions that are open-ended and designed to uncover thoughts and opinions.This Excel data sheet includes anonymous survey data
