+ ## Data Processing
69
+ - **Cumulative Metrics**: Columns with cumulative prefixes (e.g., `cumulative_relative_humidity_rmax`) start accumulating data from the previous water year, typically beginning on October 1. These metrics are not normalized unless specified.
70
+ - **Smoothing Process**: Several columns underwent a smoothing process to fill gaps in missing data. These include:
71
+ - `SWE`
72
+ - `air_temperature_observed_f`
73
+ - `precipitation_amount`
74
+ - `relative_humidity_rmin`
75
+ - `relative_humidity_rmax`
76
+ - `mean_vapor_pressure_deficit`
