Simplifying cost calculations for eLTER sites and platforms: A flexible web application for site managers

The eLTER-SO-Costs web application is a specialized tool designed to assist the eLTER (integrated European Long-Term Ecosystem, critical zone and socio-ecological Research) community in estimating the costs associated with upgrading and operating standard observations (SOs) across various eLTER sites. It provides a flexible and efficient approach to cost estimation by tailoring calculations to specific site characteristics, ensuring that cost assessments are relevant and accurate. The tool considers key factors such as the site category, habitat types, focus spheres, and the potential for co-location with other research infrastructures, all of which influence the costs. The application is designed to be highly adaptable, allowing users to customize the output according to specific needs and exclude or adjust certain predefined cost elements based on the unique conditions of their sites or platforms. The core functionality of the application allows users to input unique site-specific data and receive an automated, detailed annual cost breakdown for SOs. The eLTER-SO-Costs facilitates financial planning, enabling eLTER site managers to optimize their eLTER site management, reducing the time and effort traditionally spent on manual cost calculations, democratizing access to essential financial data for the broader eLTER community. The tool's user-friendly interface ensures that site managers and researchers, even those without expertise in cost analysis, can efficiently plan for the long-term sustainability of their sites while meeting the scientific and operational demands of ecological monitoring.
