Observational records are fundamental to scientific understanding of climate and weather. Although Climate Reanalyzer focuses on visualization tools for model-based reanalysis, forecast, and gridded data products, the links below have been organized to help users who want to access surface weather, radiosonde (upper air), and buoy (marine) observational data.
