Function to extract point data from TerraClimate

Description

Extracts variables needed for microclimate modelling from the monthly TerraClimate database described in "Abatzoglou, J. T., Dobrowski, S. Z., Parks, S. A., & Hegewisch, K. C. (2018). TerraClimate, a high-resolution global dataset of monthly climate and climatic water balance from 1958–2015. Scientific Data, 5(1), 170191. https://doi.org/10.1038/sdata.2017.191" This dataset includes climate change scenarios for +2 and +4 deg C warming (via parameter 'scenario') Michael Kearney Feb 2022

Usage

get_terra(
  scenario = 0,
  x = c(-5.3, 50.13),
  ystart = 1985,
  yfinish = 2015,
  source =
    "http://thredds.northwestknowledge.net:8080/thredds/dodsC/TERRACLIMATE_ALL/data"
)

Arguments

`scenario`	= 0, climate scenario, either 0 (historical), 2 (plus 2 deg C) or 4 (plus 4 deg C)
`x`	= c(-5.3, 50.13), location expressed as longitude, latitude, decimal degrees
`ystart`	= start year (min is 1958 for historical, 1985 for climate change)
`yfinish`	= finish year (max is 'last year' for historical, 2015 for climate change)
`source`	= "http://thredds.northwestknowledge.net:8080/thredds/dodsC/TERRACLIMATE_ALL/data", location where data is stored - defaults to opendap web location but can be retrieved locally if desired
