- SwpcClient: unparseable time_tag rows drop silently, integer / string
numerics both cast, already-decoded list bodies (Req auto-decode) are
accepted, non-JSON-array bodies return {:error, :not_a_list}, X-ray
rows whose energy isn't the long wavelength are filtered, and the
misspelled-upstream electron_contaminaton key flags
electron_contaminated.
- UwyoSoundingClient: every month abbreviation routes to its correct
number, bogus month tokens fall through to an empty result, and
short-of-fixed-width lines are skipped without raising.
- Grid.wgrib2_grid_spec/0: lon/lat_start anchor to the SW corner,
steps match Grid.step/0, cell counts span CONUS inclusive, and the
spec's cell product equals length(Grid.conus_points/0).
- PollWorker: empty-link list is a no-op, and poll_fn receives host /
community / radio_type straight from the link row.
- Contact submission_changeset: antenna heights are bounded to
[0, 1000] ft, whitespace-only mode normalises without firing an
invalid-mode error, plus a pair of StreamData properties — every
sanctioned band validates and every out-of-list band string is
rejected.
Suite: 2,380 tests + 148 properties (was 2,370 + 146); coverage
70.38% → 71.08% total; credo strict clean.
IEM's RAOB endpoint stopped keeping Canadian stations current — most
stalled around Sep 2024 — which leaves a gap in refractivity/ducting
calibration over all the CW*/CY* stations already in weather_stations.
MSC's own tephi CSV is fixed-width and rendering-focused; the WMO TEMP
bulletins would need a full decoder. University of Wyoming serves the
same stations in a clean space-delimited format, is current, and
accepts the 3-letter station code (drop the leading C from Canadian
ICAO). Its output shape matches IemClient.parse_raob_json/1 exactly,
so it drops straight into Weather.upsert_sounding/2.
- New UwyoSoundingClient with URL builder, Req-based fetch_sounding,
and a fixed-width parse_sounding_html that extracts PRES/HGHT/TEMP/
DWPT/DRCT/SKNT from the <PRE> block and DateTime from the <H2> header.
- New CanadianSoundingFetchWorker: Oban batch worker that finds all
sounding stations whose code starts with C, picks the most recently
publishable 00Z or 12Z slot (90 min publish delay), calls UWYO per
station, and upserts with SoundingParams-derived refractivity/
ducting fields.
- Oban cron at 01:30Z and 13:30Z (dev + prod) to drive the worker.
- Req.Test plug wiring in config/test.exs.
- Captured Goose Bay fixture as test/support/fixtures/uwyo_sounding_yyr.html.
Also drops two implementation plans under docs/plans/:
- 2026-04-13-rdps-vertical-profiles.md: ~2 day plan for RDPS 10 km
Canadian ducting outside HRRR's Lambert footprint.
- 2026-04-13-hrdps-canadian-prop-grid.md: ~5 day plan for the full
HRDPS 2.5 km Canadian prop grid. Explicitly recommends doing RDPS
first.
TDD throughout, 19 new tests, 1318/1318 passing, credo strict clean.
