Synthesized from method descriptions across 1 paper 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 — The influence of orbital parameters on the North American Monsoon system during the Last Interglacial Period (2021), Journal of Quaternary Science. Implementations in other papers (listed below) may differ.

1. Configure regional climate model domain
   Set up RegCM_4.4.5 model domain ranging from 128° W to 82° W along southern domain margin at ~10° N and from 150° W to 60° W along northern domain margin at ~60° N, including parts of eastern Pacific and Gulf of Mexico to accurately simulate climate pattern and source regions over oceanic areas
   Quantities: Domain spans 46° longitude by 50° latitude, horizontal resolution of 55 km, 18 vertical levelsDuration: Initial setup phaseConditions: Model physics includes representation of convective schemes, surface physics, atmospheric chemistry and aerosols, ocean-air exchanges
   Equipment: RegCM_4.4.5 regional climate model, ERA-Interim reanalysis data, NOAA optimum interpolation SST analysis
2. Design orbital parameter experiments
   Configure 4 experiments accounting for different orbital parameter configurations during LIG: modern conditions, MinObliquity (115 ka), Eemian (125 ka), and MaxObliquity (130 ka), using interglacial time slices to capture obliquity minimum and maximum phases
   Quantities: 4 separate experimental configurations, orbital parameters for 115 ka, 125 ka, and 130 ka time periodsDuration: Experimental design phaseConditions: Present-day vegetation and polar ice sheets, consistent sea surface temperatures, changing greenhouse gas concentrations
   Equipment: Orbital parameter calculations, Greenhouse gas concentration data
