MRMS
----
Layer the NOAA MRMS PrecipRate product onto the score grid so rain fade
updates every 2 minutes instead of every hour alongside HRRR. New modules:
- Microwaveprop.Weather.MrmsClient: fetches the latest .grib2.gz off the
NCEP mirror (Req auto-decompresses so no gunzip step), writes the raw
GRIB2 to a temp file, and calls the existing wgrib2 wrapper with the
0.125 propagation grid spec to get interpolated cells. Returns a
%{{lat, lon} => mm_per_hour} map with missing-value sentinels dropped.
- Microwaveprop.Weather.MrmsCache: ETS-backed GenServer mirroring
ScoreCache/GridCache. Caches a single "current" entry keyed by
valid_time with PubSub broadcast so peer nodes stay in sync and only
the Oban leader pays the fetch + regrid cost.
- Microwaveprop.Workers.MrmsFetchWorker: cron every 2 minutes, short-
circuits when the cached valid_time already matches the newest file.
Microwaveprop.Propagation.AsosNudge.compute/4 now takes an optional
rain_grid. When a cell has MRMS rain >= 0.1 mm/hr it gets patched onto
the HRRR profile's `precip_mm` field (the scorer already reads it there)
and the cell is re-scored even with no ASOS station nearby. Cells with
MRMS rain below the threshold aren't touched so dry cells keep their
raw HRRR scores (which have the wind/sky/native-gradient signal that
isn't persisted on HrrrProfile rows and would otherwise be lost).
AsosAdjustmentWorker pulls MrmsCache on every tick and passes the grid
through to AsosNudge.compute/4. Also skips the IemClient error branch
that can never happen and handles the ASOS-empty + MRMS-empty case
explicitly. MrmsCache wired into the supervision tree; MrmsFetchWorker
cron entry added to config.exs and dev.exs.
Four new AsosNudge cases cover MRMS-only re-scoring, threshold gating,
and the wet/dry score delta.
Beacons 500
-----------
Beacon.format_freq/1 and format_mw/1 crashed on whole-number floats
(e.g. 24192.0) because `frac == 0.0` could become false under float
rounding while `trim_trailing_zeros/1` stripped the decimal point,
leaving a 1-element list that couldn't be destructured as [_, frac].
Shared format_number/1 helper handles integer input directly and
pattern-matches both the "int-only" and "int + frac" shapes.
Added stream_data property tests covering the whole microwave range for
both integers and floats to catch this class of bug before prod.
UTC clock flash
---------------
The /weather and /map UTC clocks were empty until the JS hook mounted
post-WebSocket, producing a several-second blank spot on initial load
and a clobber risk on sidebar re-renders. Mount now computes a
server-rendered `initial_utc_clock` string and the template seeds the
element with that plus `phx-update="ignore"` so LiveView morphdom won't
overwrite what the hook writes.
Beacons can now record a directional bearing ("omni" or 0-360 degrees)
and a beamwidth in degrees. The keying list grows from {on_off, fsk}
to include FM Voice, WSPR, and the full Q65A/B/C/D/E × 15/30/60/120
family, grouped via optgroups in the submission form.
- Anonymous users can submit beacons (held pending admin approval)
- Added notes field to beacons (textarea on form, shown on detail page)
- Added Beacons link to /map sidebar nav (mobile + desktop),
removed stale Rover Planner link
- Moved /backfill to /admin/backfill under the admin live_session
- Beacon detail map zooms in two extra levels after fitBounds
Non-admin users can now submit beacons but they are held in an
unapproved state until an admin approves them. Only approved beacons
appear in the public list; pending submissions are shown in a separate
admin-only section on /beacons with Approve and Delete actions. The
show page surfaces a pending badge and an admin-only Approve button
when viewing an unapproved beacon.
Also formats EIRP (mW) on the index page without scientific notation.
- Add on_the_air boolean to beacons (default true); surfaced as a
checkbox on the form, a badge on the index, and in the detail list.
- Render a Leaflet map on the beacon show page with a marker at the
beacon's lat/lon tooltipped with callsign + frequency. Marker is
green when on air, gray when off.
- Compute and draw a reception-range estimate as concentric signal-
strength rings. New Microwaveprop.Beacons.RangeEstimate solves a
link budget (FSPL + O2/H2O absorption from BandConfig) at five RX
thresholds (-100 to -145 dBm), then scales by 0.5 + score/100 from
the latest Propagation.point_detail at the beacon's grid square, so
current HRRR conditions shift the rings in or out.
- Re-enable the hourly PropagationGridWorker cron and freshness
monitor in dev.exs so dev actually has HRRR-backed scores to feed
the new estimator.
- Rename beacons.height_m to height_ft; migration converts existing
values (m * 3.28084). Form/list/show labels updated.
- Beacon changeset now fills lat/lon from the grid when they're blank
(previously only the reverse worked). Lat/lon and grid inputs are no
longer marked required in the form — enter one side and the other
populates on blur via phx-change.
- Rename beacons.power_watts to power_mw (migration multiplies existing
values by 1000); form/list/show all relabeled to "Power (mW)"
- Fix Add-monitor button alignment on /users/settings by rendering the
label above and putting the input and button in a plain flex row so
the input wrapper margin no longer offsets the button
- Extend the settings page re-auth window from 10 minutes to 24 hours
Beacons:
- Scaffolded with phx.gen.live then reworked so reads are public
and mutations go through a live_session gated by the new
:require_admin on_mount hook in UserAuth
- Beacon schema stores frequency (MHz), callsign, grid, lat/lon,
power (W), and height above ground (m); grid auto-derives from
lat/lon when left blank via Maidenhead.from_latlon
- Adds Maidenhead.from_latlon/3 so we can compute grids locally
instead of hitting an external API
Users admin page:
- /users and /users/:id/edit (admin-only) for listing, editing
(callsign/name/email/is_admin), and deleting other users
- Adds Accounts.list_users, admin_update_user, delete_user, and
a dedicated admin_changeset on the User schema
- Nav gains a "Users" link for admins and a "Beacons" link for
everyone
