Pull environmental data from IMOS THREDDS server and save to local system

Description

Accesses and download environmental data from the IMOS THREDDS server

Usage

.pull_env(
  dates,
  study_extent,
  var_name,
  folder_name = NULL,
  .cache,
  .crop,
  .nrt = FALSE,
  .output_format = ".grd",
  .parallel = TRUE,
  .ncores = NULL,
  verbose = TRUE
)

Arguments

dates	detection data source in data frame with at the minimum a X, Y and date time field
study_extent	terra::ext object defining the study area from which environmental data should be cropped
var_name	variable needed options include current options ('rs_sst', 'rs_sst_interpolated', 'rs_salinity', 'rs_chl', 'rs_turbidity', 'rs_npp', 'rs_current', 'bathy', 'dist_to_land')
folder_name	name of folder within 'imos.cache' where downloaded rasters should be saved. default NULL produces automatic folder names based on study extent
.cache	should the extracted environmental data be cached within the working directory?
.crop	should the extracted environmental data be cropped to within the study site
.nrt	should NRT Ocean Current data be used if DM data is not available for certain years?
.output_format	File type for cached environmental layers. See writeFormats. The default format is 'raster'.
.parallel	should the environmental data download be conducted in parallel to speed up the process? Currently, parallel processing is only supported when downloading 'rs_current' data.
.ncores

Details

Internal function to download environmental raster layers from IMOS Thredds server (http://thredds.aodn.org.au/)

Value

a SpatRaster object with daily spatial environmental layers associated with detection dates
