disturbance_dhw.Rd

Degree Heating Weeks (DHW) Disturbance Layer

Usage

disturbance_dhw(spatial_grid, spde, config_sp)

Arguments

spatial_grid

An sfc_POINT object representing the full spatial grid.

spde

A list containing the SPDE mesh, SPDE object, precision matrix Q, and projection matrix A.

config_sp

A list with:

  • years – vector of years to simulate

  • seed – random seed

Value

A list with:

  • dhw_temporal – data frame of the DHW temporal trend

  • dhw_effects – matrix of spatial random field values

  • dhw_pts_sample – DHW effects projected onto the grid

  • dhw_pts_effects_df – long-format data frame for plotting

Details

Generates a synthetic DHW disturbance layer by combining a temporal trend with a spatial random field projected onto a spatial grid.
