Time-varying albedo

[juliasloan25]

We currently have the capability to use albedo read in from a file thanks to functionality provided by ClimaLSM. However, the albedo is read only once from the supplied data file, and does not change over time. Here, we want to extend our implementation to read in albedo as it changes over time.

CliMA/ClimaLand.jl#243 implements the necessary functionality in ClimaLSM, and we just have to update to use this new option.

  • Bare ground albedo dataset (no time dimension)
  • CESM2 albedo dataset (midmonth dates from 1/15/1850 to 12/15/2014)
  • Both datasets contain variables "lat" (dim. 192), "lon" (dim. 288), and "sw_alb" (dim. lat x lon)
    • Note that our SST and SIC datasets have lat and lon dimensions of 180 and 360, respectively

• Note that the date range in the CESM2 albedo dataset (1850-2014) is different from the range of our SST and SIC datasets (1870-2022). This is fine for now since we're running shorter-length simulations, but we may need to revisit this when we want to have longer runs.
