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.

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

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.
