Q1: The table below represents the annual average rainfall (mm) for each station A with the average of eight other stations for the period between 1946 and 1967. Check the homogeneity of the records for station A with the other stations and then correct the information using the double cumulative curve method, explaining: A In what year does a change in the fall rate system occur? b- What are the years that need to adjust readings? C- What is the value of the correction factor for heterogeneous years?
