Method synopsis

A systematic approach to test climate change impacts at multiple model resolutions by running the same scenarios at both coarse (1 km) and fine (100 m) spatial resolution. Climate scenarios are developed by perturbing baseline meteorological conditions according to projected temperature and precipitation changes.

Procedure as described in the canonical source

Steps below were extracted from the paper that introduces this protocol — Resolution matters when modeling climate change in headwaters of the Colorado River (2020), Environmental Research Letters. Implementations in other papers (listed below) may differ.

1. Prepare baseline meteorological forcing data
   Model was driven by observed meteorological datasets from water year 2006, chosen to represent baseline conditions because it most closely matched historical means of temperature and precipitation data available from two SNOTEL sites within the domain (1985-2014). Data from three meteorological stations were used: high elevation Schofield SNOTEL (3261 m, 1200 ± 230 mm annual precipitation, 0.6°C average temperature), mid elevation Butte SNOTEL (3097 m, 670 ± 120 mm annual precipitation, 2.1°C average temperature), and relatively low elevation Gothic CASTNET (2915 m, 640 ± 100 mm annual precipitation, 1.8°C average temperature).
   Quantities: 3 meteorological stations, 30-year period of record (1985-2014), water year 2006 as baselineDuration: Water year 2006 (1 year baseline)Conditions: Stations at elevations 2915 m, 3097 m, and 3261 m with different precipitation and temperature regimes
   Equipment: SNOTEL meteorological stations, CASTNET station
2. Design climate perturbation scenarios
   Twenty-seven climate simulations were developed with three temperature conditions (no change, +2°C, +4°C) and nine precipitation conditions in every combination. Precipitation perturbations were seasonally variable, testing eight likely precipitation shifts ranging from −5% of summer precipitation to +5% summer and +10% winter precipitation. Each precipitation scenario was run at three temperature conditions.
   Quantities: 27 climate scenarios total (3 temperature × 9 precipitation conditions), temperature changes of 0°C, +2°C, +4°C, precipitation changes from -5% to +10%Duration: Not specified for individual runs Based on likely scenarios for the Rocky Mountains in the IPCC report
