Parameter estimates from ARIMA models of the daily water index by site.

MA(1) is the estimated moving average term at a 1-period lag (1 day), and AR (1) is the estimated autoregressive term at a 1-period lag (1 day). Lagged values of independent variables are denoted similarly. Asterisks denote significant differences between sites. Rain Day is an indicator for days with precipitation>0, Day After Rain is the first rain free day, Rain is the quantity of precipitation (mm), La Niña (Wet Season) is an indicator for wet season La Niña phases, El Niño (Dry Season) is an indicator for dry season El Niño phases, Post-La Niña (Wet Season) is an indicator for the time directly following a La Niña phase in the wet season, Post-La Niña (Dry Season) is an indicator for the time directly following a La Niña phase in the dry season, and Post-El Niño (Dry Season) is an indicator for the time directly following a El Niño phase in the dry season.
