YFT SUPPLEMENTAL DATASET: Fully spatial simulated datasets (Simulation #: 34_66) — YFT_221cell_observations_34_66

This R data file contains 34-66 simulated data sets at the 221 5x5 grid cell level, which matches the spatial resolution used in the OM. These data are provided for your information and in a usable format if participants wish to develop spatially structured models beyond the one and four area aggregations already provided.
