Public health researchers have worked more closely with geoscientists because of the effects of climate change. Collaborations between these fields can be limited due to the size and complexity of climate data. We surveyed researchers who published research on climate and health to learn more about the challenges impacting this field. Our response sample included researchers across many countries and split across career stages. Across career stages, access to climate data for the time and area required for analyses was the primary reported barrier to data use (N = 237, 31.0%). Institutional review board and data use agreement restrictions were the primary barriers identified for data sharing (N = 295, 28.3%). More than 85% of respondents responded as somewhat or very interested in having access to analysis-ready climate/health-related datasets (96%) and video tutorials or virtual workshops on climate data management or analysis (87%). This survey highlighted interest in additional infrastructure for data identification and access, additional educational resources, and professional data services to accelerate health analyses. These findings, and the resources produced in response, can support the climate and public health research and practice community, as well as other disciplines increasing engagement with the geosciences in response to climate change.
