Built-in mapping dictionaries
83+
-----------------------------
84+
85+
Instead of a custom dictionary, you can pass a built-in mapping name in the
86+
``dictionary`` argument. Common options include:
87+
88+
- ``"ECMWF"``
89+
- ``"ECMWF_v0"``
90+
- ``"NOAA"``
91+
- ``"GFS"``

- ``"NAM"``

- ``"RAP"``
94+
- ``"HIRESW"`` (mapping available; latest-model shortcut currently disabled)
95+
- ``"GEFS"`` (mapping available; latest-model shortcut currently disabled)
96+
- ``"MERRA2"``
97+
- ``"CMC"`` (for compatible datasets loaded explicitly)
98+
99+
What a mapping name means
100+
^^^^^^^^^^^^^^^^^^^^^^^^^
101+
102+
- Base mapping names (for example ``"GFS"``, ``"NAM"`` and ``"RAP"``) map
103+
RocketPy weather keys to the current default variable naming used by the
104+
corresponding provider datasets.
105+
- These defaults are aligned with current shortcut workflows (for example,
106+
THREDDS-backed latest model sources) and may use projected coordinates
107+
(``x``/``y`` plus ``projection``) depending on the model.
108+
109+
Legacy mapping names
110+
^^^^^^^^^^^^^^^^^^^^
111+
112+
If you are loading archived or older NOMADS-style datasets, use the explicit
113+
legacy aliases:
114+
115+
- ``"GFS_LEGACY"``
116+
- ``"NAM_LEGACY"``
117+
- ``"NOAA_LEGACY"``
118+
- ``"RAP_LEGACY"``
119+
- ``"CMC_LEGACY"``
120+
- ``"GEFS_LEGACY"``
121+
- ``"HIRESW_LEGACY"``
122+
- ``"MERRA2_LEGACY"``
123+
124+
Legacy aliases primarily cover older variable naming patterns such as
125+
``lev``, ``tmpprs``, ``hgtprs``, ``ugrdprs`` and ``vgrdprs``.
126+
127+
.. note::
128+
129+
Mapping names are case-insensitive. For example,
130+
``"gfs_legacy"`` and ``"GFS_LEGACY"`` are equivalent.
131+
132+
For custom dictionaries, the canonical structure is:
133+
134+
.. code-block:: python
135+
136+
mapping = {
137+
"time": "time",
138+
