Video Demo of the Dairy Cattle Methane Emission Prediction Model Testing Platform. In this study we developed a DC CH4 emission prediction model testing platform, which allows researchers to upload and assess the performance of their locally developed prediction models, against a global repository (GR) of intercontinental DC CH4 emission prediction models published in the literature. A simulated DC CH4 emission dataset based on the European region comes prepopulated within the application, yet the platform also allows researchers to upload their own local datasets, which the GR is revaluated on and subsequently, uploaded models can be compared against.It is hoped that the platform developed will provide an accessible tool for researchers to assess the adaptability of the local DC CH4 emission prediction models they have developed, as well as review the applicability of a GR of published DC CH4 emission prediction models in their particular region, both of which can help refine the development of local prediction models, as well as identify potential prediction models for the implementation of mitigation solutions in respective regions.
