get_temp: get water temperatures from a GLM simulation

In USGS-R/glmtools: Tools for working with the General Lake Model (GLM)

get water temperatures from a GLM simulation

Description

Creates a data.frame with DateTime and temperatures (in deg C).
Temperatures that are sampled out of the GLM output are taken relative to the surface (reference = 'surface') or the bottom of the lake (reference = 'bottom').

Usage

get_temp(
  file = "output.nc",
  reference = "bottom",
  z_out = NULL,
  t_out = NULL,
  ...
)

Arguments

file	a string with the path to the netcdf output from GLM
reference	a string which specifies the vertical reference ('surface' or 'bottom')
z_out	an optional vector of depths for temperature output (in meters). If NULL, depths will be determined based on the depth of the lake
t_out	a vector of POSIXct dates for temporal resampling (order is important)
...	additional arguments passed to resample_sim()

Value

a data.frame with DateTime and temperature at depth

Examples

sim_folder <- run_example_sim(verbose = FALSE)
nc_file <- file.path(sim_folder, 'output/output.nc')
temp_surf <- get_temp(nc_file, reference = 'surface', z_out = c(0,1,2))
temp_bot <- get_temp(nc_file, reference = 'bottom', z_out = c(0,1,2))
temp_bot <- get_temp(nc_file)

#-- get temporal subset--
t_out <- seq(as.POSIXct("2015-04-15"), as.POSIXct("2015-06-01"), by = 86400)
temp_surf <- get_temp(nc_file, reference = 'surface', z_out = 0, t_out = t_out)
plot(temp_surf)
