A new study uncovers a critical challenge in accurately classifying precipitation as rain or snow using surface weather data. Accurately identifying precipitation phase is critical for weather forecasting, hydrologic modeling, and climate research, with significant implications for transportation. A t temperatures near freezing, however, all traditional methods struggle to accurately predict rain and snow due to the meteorological similarity of the two phases. Leveraging multi-source data integration rather than relying on surface weather data alone may offer improvements. ...read more read less
