A high-resolution Typical Meteorological Year dataset for solar radiation evaluation in Australia

High spatiotemporal resolution Typical Meteorological Year (TMY) data are essential for building energy modeling and urban climate studies. However, conventional TMY datasets, limited by sparse ground-based station coverage and outdated updates, fail to meet the demands of detailed urban-scale simulations. To overcome these limitations, we developed a high-resolution TMY-MER dataset for Australia based on MERRA2 reanalysis data. The multidimensional error assessment framework significantly enhances the reliability of reanalysis data for use in complex climate zones, supporting dynamic energy system planning and urban thermal environment modeling.
