What is the Normal Ratio Method used for?
Think about how we can use data from other sources.
What do we need from neighboring stations to use the Normal Ratio Method?
What types of data do you think are crucial for estimation?
What is the purpose of the Normal Ratio Method?
Consider why we use this method.
True or False: The Normal Ratio Method does not require long-term normal rainfall data.
Think about what is needed for accurate rainfall data.
Station X has no reported rainfall data for a month, but the nearest stations report 400 mm and 600 mm with 30-year normals of 300 mm and 500 mm. Use the Normal Ratio Method to estimate missing data for Station X.
Make sure to apply the formula correctly and carefully.
Critique the application of the Normal Ratio Method in a scenario where only one reliable neighboring station exists.
Consider the importance of data diversity.
