README for WRF model data
*************************

By Øivind Hodnebrog (oivind.hodnebrog@cicero.oslo.no), CICERO, August 2021.

The dataset contains WRF model data used in a manuscript under review for publication in Climate Dynamics: "Understanding Model Diversity in Future Precipitation Projections for South America" by Ø. Hodnebrog et al., and I refer to that manuscript for further details about the results.

The overall folder WRF_results consists of the following (tarred and gzipped) subfolders:
- WRF_ACC: Downscaled results using ACCESS1-0 as initial and boundary conditions to WRF (1996-2005 and 2091-2100 RCP8.5)
- WRF_CCSM4: Downscaled results using CCSM4 as initial and boundary conditions to WRF (1996-2005 and 2091-2100 RCP8.5)
- WRF_CCSM4_cpGF: As WRF_CCSM4, but short sensitivity run for Peru with different CP scheme (1996-1998 and 2091-2093 RCP8.5)
- WRF_CCSM4_large: As WRF_CCSM4, but short sensitivity run with large domain for Peru (1996-1998 and 2091-2093 RCP8.5)
- WRF_CCSM4_noCP: As WRF_CCSM4, but short sensitivity run for Peru without CP scheme (1996-1998 and 2091-2093 RCP8.5)
- WRF_CCSM4_topo: As WRF_CCSM4, but short sensitivity run for Peru with smoothed terrain (1996-1998 and 2091-2093 RCP8.5)
- WRF_CESM: Downscaled results using CESM1-CAM4 as initial and boundary conditions to WRF (1986-2005, 2041-2060 RCP4.5 and 2081-2100 RCP8.5)
- WRF_NNRP: Downscaled results using NNRP reanalysis as initial and boundary conditions to WRF (1986-2005)

For each year of the simulations, there are files for each of four domains/regions:
- d01: South America in 50 km horizontal resolution (approximately the same domain as in CORDEX)
- d02: Central Chile in 10 km horizontal resolution
- d03: Peru in 10 km horizontal resolution
- d04: Southern Brazil in 10 km horizontal resolution (12 km for WRF_NNRP and WRF_CESM)

There are two types of files with WRF results:
- wrfout_d0X_YYYY-MM_monthly.nc: Monthly averages of several instantaneous variables
- wrfout_d0X_YYYY-MM_daily.nc: Daily accumulated precipitation (in mm) split into convective (RAINC) and non-convective (RAINNC) precipitation
