Particulates Database (``pdb``)
==================================

The ``pdb`` is the database for particulates in ``ExoJAX``, namely the microphysics of clouds.
Currently, the refractive index is downloaded from ``VIRGA`` and made available within ``pdb``.


.. code:: ipython3
    
    from exojax.spec.pardb import PdbCloud
    miedir = "/home/kawahara/exojax/documents/tutorials/.database/particulates/virga"
    pdb = PdbCloud("MgSiO3", path=miedir)


For specific examples, please refer to 
:doc:`comp_pymiescatt`
for example.
