Sacramento & Colorado River series

If you are new to lookup, before you begin you may want to take a look at our tutorial to get things started.

There are four versions of lookup that target Sacramento and Colorado River (Lee's Ferry) streamflow. Two of these use data from the instrumental record and two use data from the paleo record.

Instrumental record:

>> Aleutian low
Focuses on patterns between the Sacramento and Colorado River, North Pacific Index anomalies (NPI; Trenberth and Hurrell 1994), and the Aleutian Low Pressure Index (ALPI; Beamish et al. 1997).

>> ENSO
Focuses on patterns between the Sacramento and Colorado River, the March-May bivariate ENSO index, and the December-February bivariate ENSO index (Smith and Sardeshmukh 2000).

Paleo record:

>> Paleo Aleutian low
Focuses on patterns between tree-ring reconstructions of the Sacramento and Colorado River (Meko et al. 2001; Meko et al. 2007), and reconstructions of coastal surface air temperature in the Gulf of Alaska (as proxy for the Aleutian low; Wilson et al. 2007).

>> Paleo ENSO
Focuses on patterns between tree-ring reconstructions of the Sacramento and Colorado River (Meko et al. 2001; Meko et al. 2007), and reconstructions of Equatorial Pacific sea-surface temperature anomalies (ENSO Niño 3.4 Index; Li et al. 2013).
