Package to subsample, or interpolate, climatologies like WOA to any coordinates.

This package started with functions to obtain climatological values to compare with measured data, allowing a quality control check by comparison. It hence needed to work for any coordinates requested. I split these functionalities from `CoTeDe `_ into this standalone package to allow more people to use it for other purposes.

* Documentation: https://oceansdb.readthedocs.io.

Features

--------

- If the database files are not localy available, automatically download it.

- Extract, or interpolate if necessary, climatologic data on requested coordinates;

  - Can request a single point, a profile or a section;

  - Ready to handle -180 to 180 or 0 to 360 coordinate system;

- Ready to use with:

  - World Ocean Atlas (WOA)

  - CSIRO Atlas Regional Seas (CARS)

  - ETOPO (topography)

Quick howto use

---------------

Inside python:

.. code-block:: python

    >>> import oceansdb

    >>> with oceansdb.WOA() as db:

Find out what is available:

.. code-block:: python

    >>>     db.keys()

Average temperature at one point:

.. code-block:: python

    >>>     t = db['sea_water_temperature'].extract(var='mean', doy=136.875, depth=0, lat=17.5, lon=-37.5)

A profile of salinity:

.. code-block:: python

    >>>     t = db['sea_water_salinity'].extract(var='mean', doy=136.875, depth=[0, 10, 15, 18], lat=17.5, lon=-37.5)

A full depth section of temperature:

.. code-block:: python

    >>>     t = db['sea_water_temperature'].extract(var='mean', doy=136.875, lat=17.48, lon=[-39, -37.5, -35.2])

Using CARS instead of WOA:

.. code-block:: python

    >>> with oceansdb.CARS() as db:

    >>>     t = db['sea_water_temperature'].extract(var='mean', doy=136.875, lat=17.48, lon=[-39, -37.5, -35.2], depth=[0,10,120,280])

Or to get topography for one point from the 1 min arc resolution:

.. code-block:: python

    >>> with oceansdb.ETOPO(resolution='1min') as db:

    >>>     h = db['topography'].extract(lat=17.5, lon=0)
