ArWen 2.9.7

ArWen 2.9.7. The desktop stays ArWen Desktop 1.0.10, from the 2.9.0 release.

• Install or upgrade: pip install --upgrade "gpuwm[all-cu12]==2.9.7".
• Integration kit, verification records, and checksums.
• Node GPU gate: Stage 1 and both GPU-shard results, with the tested source revision and card identity.

New

• Run controls: per-nest history intervals, a quick-look stream between full frames (quicklook = { every_s, history_vars }), an LES closure below 250 m, the storm nest size and an inner nest.
• Moving nest-downs: gpuwm downscale --follow storm|parent|fixed|target and --warm-from.
• Every run and ensemble member writes the any-point column store (rw-store v2), so soundings can be drawn at any point and hour after the run.
• IFS HRES open data at 0.1 degree (ecmwf-open-data-0p1) at any posted cycle and lead.
• RRFS ensemble members start with their same-cycle deterministic companion, which supplies the land state and the column above the member's 250 hPa top.
• HRRR v4 climate statistics (output_diagnostics, diag_int, wind_int) and the HRRR initial-history reflectivity.
• A sub-hourly history subset beside hourly full frames ([output] full_history_interval_s).
• Children finer than 4 km (gpuwm downscale --point, --source hex-global) default to the HRRR-shape suite; --physics-profile ID or parent chooses.
• A hydrometeor handed to a child (another model's analysis, a downscale, the specified ring) arrives with a number that matches its mass.
• Cyclone runs: a rain swath product, and moving-nest accumulations kept in one fixed frame across moves.
• 5 km CONUS forecasts stream on a 32 GB card.
• CONUS hydro from EPA NHDPlus V2.1 with pip install "gpuwm[hydro-conus]".
• Remote resumes find prepared bundles and checkpoints across chain names.
• Branched ensembles (gpuwm ensemble --branch-from) share each card among several members (--members-per-card auto) and draw their maps on every core; branched members write column stores, and ensemble maps carry their map transform for any-point soundings.

Fixed

• gpuwm go with the default products on grids whose spacing is not a whole kilometre.
• Maps: isobar labels and H/L marks are drawn over wind barbs; the sounding location inset has world coastlines; the ensemble paintball map has a member legend; the meteogram's end barbs stay inside the panel.
• --cyclone-products works with ensembles and with tiles; gzipped b-decks, track times in UTC, and Earth-2 storm: auto picks the named storm's low.
• The 30 m terrain overlay takes a following nest's all-ocean first footprint; the corridor terrain mosaic and its resample run on every core.
• Morrison runs a small domain in one launch; the start state, the regional hex static and polygon meshes build on every core; nested adaptive runs land on output times with fewer steps; rw_mpas_stream encodes on every core.
• rw_wrfbatch no longer overflows its stack importing a 1 km hex region frame.
• mp=28 downloads the pinned WIF aerosol climatology or refuses by name; the synthetic profile is used only when named. --recipe hrrr and hrrr_v4 are accepted, and --recipe takes --forecast-start-hour.
• Ensemble preparation: one download per object and an atomic HRRR bridge gate.
• RUC: the soil-moisture floor after the 0 m anchor, and partial sea-ice albedo and emissivity seeds.
• MPAS-route exports read reflectivity from the diag stream.
• A streamed moving nest's checkpoint keeps its accumulation archive.
• gpuwm run --wrfinput and --met-em stream a forecast the card cannot hold resident instead of refusing it.
• GFS archive cycles with no index read their level ladder from the object; HRRR coastal matching works at an open window edge; hydro parameters handle catchments leaving the window; two --prepare-only launches in one second get two run folders.
• The 1 km nest of an HRRR 3-1 tree and ICON global source normalization initialise on every core.
