Preprocessed data of Atlas in EUCP-WP2

We provide some notebooks that check the original/raw data, fix/add the metadata using CF-conventions https://cfconventions.org/Data/cf-conventions/cf-conventions-1.9/cf-conventions.html and save data in a NetCDF format. See https://github.com/eucp-project/atlas/blob/main/python/README.md.

The pre-processed data follows the following standards:

coordinates

  • climatology_bounds (climatology_bounds) datetime64[ns] ['2050-06-01', '2050-09-01', '2050-12-01', '2051-03-01']
  • time (time) (datetime64[ns]) [2050-07-16 2051-01-16] # "JJA", "DJF"
  • latitude (lat) (float64) [30, ..., 75]
  • longitude (lon) (float64) [-10, ..., 40]
  • percentile (percentile) (int64) [10, 25, 50, 75, 90]

variables

  • tas (time, latitude, longitude, percentile) (float64)
  • pr (time, latitude, longitude, percentile) (float64)

attributes

The attributes of variables and coordinates are defined as:

  • "tas": {
    "description": "Change in Air Temperature",
    "standard_name": "Change in Air Temperature",
    "long_name": "Change in Near-Surface Air Temperature",
    "units": "K",

    },
  • "pr": {
    "description": "Relative precipitation",
    "standard_name": "Relative precipitation",
    "long_name": "Relative precipitation",
    "units": "%",

    },
  • "latitude": {"units": "degrees_north", "long_name": "latitude", "axis": "Y"},
  • "longitude": {"units": "degrees_east", "long_name": "longitude", "axis": "X"},
  • "time": {

    "climatology_bounds": ["2050-6-1", "2050-9-1", "2050-12-1", "2051-3-1"],
    "description": "mean changes over 20 years 2041-2060 vs 1995-2014. The mid point 2050 is chosen as the representative time.",
    },
  • "percentile": {"units": "%", "long_name": "percentile", "axis": "Z"},

The attributes of the data is defined as:

  • "description": "Contains modified institute method data used for Atlas in EUCP project.",
