An Overview of ERA5 Reanalysis Datasets

An ERA5 Dataset is defined to be a module containing ERA5 Reanalysis data from the Climate Data Store, and is to distinguish between datasets with differing time-resolution, from hourly to monthly.

ERA5 reanalysis data is stored on the Climate Data Store in several different categories, so different people with different needs may access different data types depending on their research. In ERA5Reanalysis, we defined these datasets as ERA5Dataset Types.

When defining an ERA5Dataset container, we also indicate the start and end dates of the dataset that we want to work on.

ERA5Reanalysis.ERA5Dataset — Type

ERA5Dataset

Abstract supertype for ERA5 reanalysis datasets, with the following subtypes:

ERA5CDStore <: ERA5Dataset
ERA5Custom  <: ERA5Dataset
ERA5Dummy   <: ERA5Dataset

All ERA5Dataset Types contain the following fields:

path : The specified directory in which to save the data
emask : The specified directory in which to save the LandSea dataset

All ERA5CDStore and ERA5Custom Types also contain the following additional fields:

ID : The module ID, that also acts as a prefix to filenames
name : The full name of the module
start : The date for which downloads/analysis begins
stop : The date for which downloads/analysis finishes
sldoi : Single-Level DOI (N/A for ERA5Daily)
pldoi : Pressure-Level DOI (N/A for ERA5Daily)
ptype : Product type (N/A for ERA5Daily), set to reanalysis
