Dense gauge observations-based evaluation of gridded precipitation in southwest China and its implication for future data development

Key Points

• This evaluation emphasizes the discrepancy between gauge observations and gridded precipitation data, affecting accuracy.
• The study found an average deviation of 20% between observed and predicted precipitation values in certain regions.
• Observational analysis of dense gauge data across multiple locations was conducted over a two-year period.
• These findings highlight the need for improved data collection techniques to enhance climate modeling efforts.
