support for era-5-land

[everydayduffy]

Hello,

Recently, the ERA5-land dataset was released. I'm trying to use wf_request to obtain this data, but am unsure what I should put as my product_type and dataset variable in the request list. If you have any advice that would be much appreciated. Here is an example request:

# area of interest
ar <- paste0(5,"/",-2,"/",1,"/",2)

request <- list(
      area = ar,
      product_type = "reanalysis-era5-land",
      format = "netcdf",
      variable = c("2m_temperature", "2m_dewpoint_temperature", 
                   "10m_u_component_of_wind", "10m_v_component_of_wind"),
      year = "2007",
      month = c("01", "02", "03", "04", "05", "06", "07", "08", "09", "10", "11", 
                "12"),
      day = c("01", "02", "03", "04", "05", "06", "07", "08", "09", "10", "11", 
              "12", "13", "14", "15", "16", "17", "18", "19", "20", "21", "22", 
              "23", "24", "25", "26", "27", "28", "29", "30", "31"),
      time = c("00:00", "01:00", "02:00", "03:00", "04:00", "05:00", "06:00", 
               "07:00", "08:00", "09:00", "10:00", "11:00", "12:00", "13:00", 
               "14:00", "15:00", "16:00", "17:00", "18:00", "19:00", "20:00", 
               "21:00", "22:00", "23:00"),
      dataset = "reanalysis-era5-land",
      target = "test.nc")

Have you seen the documentation here on how to transform the API request to an R request using the rstudio addin?

https://khufkens.github.io/ecmwfr/articles/cds_vignette.html

This is what you get if you do so:

request <- list(
  format = "netcdf",
  variable = c("10m_u_component_of_wind", "10m_v_component_of_wind", "2m_dewpoint_temperature", "2m_temperature"),
  year = "2007",
  month = c("01", "02", "03", "04", "05", "06", "07", "08", "09", "10", "11", "12"),
  day = c("01", "02", "03", "04", "05", "06", "07", "08", "09", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20", "21", "22", "23", "24", "25", "26", "27", "28", "29", "30", "31"),
  time = c("00:00", "01:00", "02:00", "03:00", "04:00", "05:00", "06:00", "07:00", "08:00", "09:00", "10:00", "11:00", "12:00", "13:00", "14:00", "15:00", "16:00", "17:00", "18:00", "19:00", "20:00", "21:00", "22:00", "23:00"),
  dataset = "reanalysis-era5-land",
  target = "download.nc"
)

This should work, adjust the area manually.

Brilliant. Looks like product_type is absent for these requests. That seems to be working. Thanks for your quick response and also thank you for developing such a useful package!
