Time series & trends

Every variable in the dataset, with its Theil–Sen slope and Mann–Kendall p-value. Click any row to open the annual time series, a 12-month rolling trend (long-term direction without the annual cycle), and a togglable seasonal climatology for three 15-year periods so the shift in seasonal pattern is visible.
