Method synopsis

Spatial averaging of gridded precipitation data over selected headwater basins to create seasonal and annual precipitation totals for water balance analysis.

Synthesized from method descriptions across 3 papers using this protocol.

Procedure from a recent peer-reviewed implementation

Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Recent Upper Colorado River Streamflow Declines Driven by Loss of Spring Precipitation (2024), Geophysical Research Letters. Implementations in other papers (listed below) may differ.

1. Collect gridded precipitation data
   Gridded UCRB precipitation data were collected from the Parameter-elevation Regressions on Independent Slopes Model, PRISM for the 1964-2022 period. The monthly precipitation product was spatially averaged over each selected basin. Seasonal and annual aggregates of precipitation were created for each basin for each water year in the data record.
   Quantities: 59 years of data (1964-2022), 26 basinsDuration: 1964-2022 periodConditions: Monthly data aggregated to seasonal and annual totals
   Equipment: PRISM Climate Group database
