gpuwm-data
Physics reference tables and map assets for gpuwm.
Install gpuwm and this arrives with it:
pip install gpuwm
You do not install this package by hand and you do not choose it. gpuwm
declares gpuwm-data==<its own version> as a hard dependency, because a
gpuwm that cannot run radiation or Thompson microphysics is not an
install. There is no extra to remember and no post-install step.
Why it is a separate distribution
PyPI rejects any file over 100 MiB. The 2.5.0 gpuwm wheel measured
103.62 MiB. These two directories of pure reference data were 64.21 MiB of
that, so they ship here and gpuwm ships at 39.41 MiB. In 2.8.7 three new
native executables put the gpuwm manylinux wheel near the limit again,
and two incompressible archives moved here as single files: the bundled
historical case catalog and the WRF v4.6.1 SPP oracle captures. The
air-quality line then moved the WRF-Chem aerosol optics tables here.
What is in it
| Directory | Contents |
|---|---|
gpuwm_data/data/rrtmgp/ |
RTE+RRTMGP k-distribution and cloud-optics NetCDFs, the trace-gas climatology RRTMGP derives from the RFMIP inputs, and the license and provenance texts that document them |
gpuwm_data/data/thompson/tables/ |
The Thompson microphysics lookup tables generated by WRF v4.6.1's thompson_init, plus CCN_ACTIVATE.BIN for the aerosol-aware variant, under MANIFEST.sha256 |
gpuwm_data/data/basemap/ |
The Natural Earth and US Census shapefiles the renderer draws coastlines, borders, state lines and counties from |
gpuwm_data/data/case-catalog/historical.zip |
The historical case catalog gpuwm case-catalog opens when --catalog is omitted, with its merge provenance inside the archive |
gpuwm_data/data/spp/native-wrf461.zip |
Stochastic-parameter-perturbation captures from unmodified WRF v4.6.1 modules, read by the SPP consumer gates, with their receipt inside the archive |
gpuwm_data/data/chem/optics/ |
WRF-Chem v4.7.1's GOCART Mie tables and component data the chem aerosol optics read, under table-sha256sums.txt, with their provenance |
Every byte is data. There is no compiled code and no platform coupling,
so one py3-none-any wheel serves every platform gpuwm runs on.
Two of the Thompson tables are not here: freezeH2O.dat (243 MiB) and
qr_acr_qg_V4.dat (71 MiB) are each over the same PyPI limit that split
this package out. They are published as GitHub release assets and staged
by gpuwm fetch-tables, byte-verified against the pins in
gpuwm.core.thompson_contract. Only mp_physics=8/28 runs need them.
Reading it
gpuwm resolves these paths through gpuwm.data_assets, which is the only
supported way in. If you want the directory yourself:
import gpuwm_data
gpuwm_data.data_root() / "rrtmgp" / "rrtmgp-gas-lw-g256.nc"
Provenance and licensing
The code here is Apache-2.0. The data is not uniformly so, and each
directory carries its own texts: see data/rrtmgp/PROVENANCE.md with its
LICENSE and LICENSE-CC-BY-SA-4.0 files, and gpuwm's own
gpuwm/data/thompson/PROVENANCE.md for the WRF-derived Thompson tables.
The map assets are public domain; data/basemap/PROVENANCE.md names their
sources.
No RFMIP file is carried here or in the source repository: the four
reference results are CC-BY-NC-SA-4.0 and the input file's terms are
ambiguous, so the tests that read them fetch them from upstream at test
time, and RRTMGP runs on a 136-number table derived from the inputs.
