==========================================================
Argo data access to global ocean in situ observing system.
==========================================================
In order to ease Argo data analysis for the vast majority of standard users, we implemented in argopy different levels of verbosity and data processing to hide or simply remove variables only meaningful to experts. Let argopy manage data wrangling, and focus on your scientific analysis.

If you don’t know in which category you would place yourself, try to answer the following questions:

    - [] what is a WMO number ?

    - [] what is the difference between Delayed and Real Time data mode ?

    - [] what is an adjusted parameter ?

    - [] what a QC flag of 3 means ?

If you don’t answer to more than 1 question: you probably will feel more comfortable with the standard or research user modes.

By default, all argopy data fetchers are set to work with a standard user mode, the other possible modes are research and expert.

**What it does**

This tool based on argopy is able to fetch (i.e. access, download, format) Argo data into netcdf files.


**Input description**

- This tool provides 3 user modes:

    - 🏄 expert mode return all the Argo data, without any postprocessing,

    - 🏊 standard mode simplifies the dataset, remove most of its jargon and return a priori good data,

    - 🚣 research mode simplifies the dataset to its heart, preserving only data of the highest quality for research studies, including studies sensitive to small pressure and salinity bias (e.g. calculations of global ocean heat content or mixed layer depth).

- The tool provides 3 different data selection methods:

    - 🗺 For a space/time domain (to select data for a rectangular space/time domain)

    - 🤖 For one or more floats (if you know the Argo float unique identifier number called a WMO number you can use this mode)

    - ⚓ For one or more profiles (specify the float WMO platform number and the profile cycle number(s) to retrieve profiles)

- The tool can retrieve data from :

    - ⭐ the Ifremer **erddap** server (Default). The erddap server database is updated daily and doesn’t require you to download anymore data than what you need. You can select this data source with the keyword erddap and methods described below. The Ifremer erddap dataset is based on mono-profile files of the GDAC. Since this is the most efficient method to fetcher Argo data, it’s the default data source in argopy.
    
- With this tool you can thus get access to the following Argo data:

    - the **phy** dataset, for physical parameters. This dataset provides data from floats that measure temperature, salinity, pressure, without limitation in depth. It is available from all Available data sources. Since this is the most common Argo data subset it’s selected with the phy keyword by default in argopy.

    - the **bgc** dataset, for biogeochemical parameters.This dataset provides data from floats that measure temperature, salinity, pressure and oxygen, pH, nitrate, chlorophyll, backscatter, irradiance, without limitation in depth. You can select this dataset with the keyword bgc and methods described below.


**Output**

You can retrieve the Argo data in one netcdf file.
