Download OISST data — download

Function to download and save NetCDF files for CoralTemp download_OISST() is a function to download OISST v2.1

If the number of cores is set to >1, the function uses mclapply to parallel download datasets, else 1 = single downloads.

Notes: The NOAA 1/4° Daily Optimum Interpolation Sea Surface Temperature (OISST) is a long term Climate Data Record that incorporates observations from different platforms (satellites, ships, buoys and Argo floats) into a regular global grid. The dataset is interpolated to fill gaps on the grid and create a spatially complete map of sea surface temperature. Satellite and ship observations are referenced to buoys to compensate for platform differences and sensor biases.

Usage

download_OISST(
  url =
    "https://www.ncei.noaa.gov/data/sea-surface-temperature-optimum-interpolation/v2.1/access/avhrr/",
  start_date,
  end_date,
  dest_dir,
  mc.cores = 1
)

Arguments

url: one of the NOAA thredds url
start_date: end year
end_date: end year
dest_dir: save file location
mc.cores: set the number of cores

Value

downloaded nc files to specified location

Examples

if (FALSE) { # \dontrun{
