Defining ERA5 Datasets

Defining an ERA5Dataset is easy. All you need to define are two things:

1. Date range, ranging from start to stop

2. Data path, i.e. where you want to save the ERA5 Reanalysis Data

DatasetFunction(
    start = Date(),
    stop  = Date(),
    path  = ...
)

Setup

using ERA5Reanalysis

Example for an Hourly Dataset

See below for an example of defining an ERA5Hourly dataset:

e5ds = ERA5Hourly(start=Date(2017,2,1),stop=Date(2017,2,1),path=homedir())

The ERA5Hourly Module has the following properties:
    Dataset ID        (ID) : era5hr
    Date Begin     (start) : 2017-02-01
    Date End        (stop) : 2017-02-28
    Data Directory  (path) : /home/runner/era5hr
    Mask Directory (emask) : /home/runner/emask

e5ds.start

2017-02-01

e5ds.stop

2017-02-28

typeof(e5ds)

ERA5Hourly{String, Date}

typeof(e5ds) <: ERA5Dataset

true

Note that the resultant ERA5Hourly dataset processes data by whole-months. It is not possible to specify specific days in which to download data.

Example for a Monthly Dataset

And below for an example of defining an ERA5Monthly dataset with a custom home directory:

e5ds = ERA5Monthly(start=Date(2017,1,2),stop=Date(2018,5,1),path=pwd())

The ERA5Monthly Module has the following properties:
    Dataset ID        (ID) : era5mo
    Date Begin     (start) : 2017-01-01
    Date End        (stop) : 2018-12-31
    Data Directory  (path) : /home/runner/work/ERA5Reanalysis.jl/ERA5Reanalysis.jl/docs/build/datasets/era5mo
    Mask Directory (emask) : /home/runner/work/ERA5Reanalysis.jl/ERA5Reanalysis.jl/docs/build/datasets/emask
    Hour-of-Day?   (hours) : false

e5ds.start

2017-01-01

e5ds.stop

2018-12-31

typeof(e5ds)

ERA5Monthly{String, Date}

Note that the resultant ERA5Monthly dataset processes data by years. It is not possible to specify specific months in which to download data. The same holds true for the ERA5MonthlyHour dataset.

Example for a Monthly-Hour Dataset

e5ds = ERA5Monthly(start=Date(2017,1,2),stop=Date(2018,5,1),hours=[0,3,6,9,12,15,18,21])

typeof(e5ds)

ERA5Monthly{String, Date}
