Maps depicting the change in the number of observed RxDays across the western United States (WUS) on an annual (a) and seasonal (b–e) basis. The trend in RxDays is calculated using a linear least squares regression and is represented graphically by the accumulated change (in RxDays per year or season) over the full 40-year period using meteorological data from the GridMET dataset (1981–2020).
