Surface conditions remain live. The multi-layer pressure profile will appear after its independent feed recovers.
Unavailable for the selected weather target. Each field reports its own lineage; unavailable fields are not presented as observations. This panel is not an RF retrieval.
Weather drivers set the simulated atmosphere. Historical RF datasets calibrate or challenge selected effects; they do not become live ground-to-LEO measurements.
No atmospheric profile is currently loaded.
GEOMETRY Earth-fixed numerical-weather grid sampled along a modeled ground-to-LEO ray.
LOCAL DATA Nine compact 6-epoch 4×4×4 event cubes plus one original higher-resolution Iowa fixture; 14 days of San Diego pressure-level columns occupy about 0.5 GB.
FIELDS temperature · pressure · relative humidity · height · horizontal and vertical wind · cloud cover (live) / cloud liquid mixing ratio (offline fixtures) HRRR is analysis/forecast weather, not a received satellite RF observation. The live point-profile broker does not expose native liquid, ice, rain, snow, or graupel mixing ratios.
No point-sampled MRMS observation is attached to this station.
GEOMETRY CONUS radar mosaic point-sampled at a station or intersected with a modeled slant path.
LOCAL DATA 2,928 uncropped CONUS GRIB2 files across three products and two 2024 San Diego event days, totaling 2,336,588,802 bytes (2.18 GiB).
FIELDS instantaneous precipitation rate · radar-only hourly QPE · multi-sensor hourly QPE MRMS describes precipitation from ground radar and gauge synthesis; it is not an RF link measurement. The local rain-labelled subset is only two days wide; the separate live adapter supplies one point rather than the raw CONUS volume.
Historical calibration, validation, and profile priors · 4 sources Paired Ku-band received-signal level and path rainfall for calibrating rain-attenuation response.
GEOMETRY 215 fixed GEO satellite-microwave downlinks in France, not moving ground-to-LEO links.
COVERAGE August through December 2022 at one-minute cadence, with radar path rainfall and 113 rain gauges.
FIELDS Ku-band received signal level · per-link geometry · radar path rainfall · rain-gauge rainfall · ERA5 freezing level
LOCAL CORPUS Three NetCDF files covering 215 links and 220,320 one-minute steps; the local forward fit contains 1.97 million wet link-minutes, pooled correlation 0.629, and calibrated RMSE 0.873 dB. Interpretation limits GEO geometry does not reproduce LEO motion, Doppler, handover, or changing elevation. The dataset supports Ku rain-fade calibration, not coherent phase, CSI, or a complete LEO channel model. ERA5 contributes the freezing-level field, so it is not independent weather truth for that variable. Actual Starlink service and local-weather measurements for evaluating weather-associated user impact.
GEOMETRY Real ground-to-LEO Starlink service, but without a calibrated satellite, beam, carrier, or RF-observable record.
COVERAGE Contiguous fixed-site Starlink and Froggit weather measurements from the published campaign.
FIELDS throughput · latency · packet drop · obstruction fraction · surface weather
LOCAL CORPUS An 805 MB nested shallow clone containing raw and preprocessed measurements, plots, and analysis scripts; the local weather/performance join contains 116,956 measurements. Interpretation limits Application-layer performance is heavily confounded by routing, congestion, firmware, beam handover, and terminal state. The firmware-era dish SNR field is obsolete or masked; no calibrated RSSI, C/N0, phase, I/Q, or CSI is exposed. Use this corpus for service-impact validation, never as physical RF-channel truth. Ground GNSS meteorology for learning neutral delay, precipitable-water, and thermodynamic priors.
GEOMETRY Ground-to-GNSS paths, predominantly MEO and L-band; not Ku-band ground-to-LEO geometry.
COVERAGE 577 daily CONUS NetCDF files from 414 stations spanning 2023 through 2024-08-11.
FIELDS zenith delay features · precipitable water vapor · temperature · relative humidity · masked rain target
LOCAL CORPUS 486 MB raw; 9,235,392 processed rows and 1,200,000 overlapping supervised windows, with a 279-station frozen split. Interpretation limits Ground-to-GNSS L-band delay does not reproduce Ku attenuation, LEO motion, or a commercial LEO terminal channel. The 1.2 million windows overlap, so adjacent windows are not independent captures. Use as a neutral-atmosphere prior or benchmark, not as direct ground-to-LEO RF labels. Limb-sounding refractivity and wet-profile evidence for atmospheric-profile priors and transfer studies.
GEOMETRY GNSS transmitters observed by LEO receivers through an atmospheric limb occultation; not LEO-to-ground.
COVERAGE Five selected days of 2024 across development and season-disjoint local trees.
FIELDS 100 Hz excess phase and SNR · bending angle · refractivity · temperature · pressure · moisture profiles
LOCAL CORPUS About 24 GB for days 001, 002, 091, and 274 plus a 1.9 GB held-out day 183 tree; the multi-season profile table contains 11,079 events. Interpretation limits Occultation rays are near-horizontal limb paths between GNSS and LEO spacecraft, not ground-to-LEO communication paths. Level-2 wetPf2 is a 1D-Var retrieval with an NWP first guess, not independent radiosonde truth. The five locally mirrored days are a sampled corpus, not the complete COSMIC-2 archive.

GEOMETRY CONDITION -- lower is better; solver rejects rank-deficient views
A 3D velocity solution needs rain plus at least four delay-gated bistatic observations with independent geometry.
OSSE only. A Doppler sample is admitted only when the scattered path is delay-resolved and the explicit scenario echo SNR/clutter margins pass their gates. These margins are not inferred from the communications carrier. Missing rain/wind, weak echoes, unresolved delay, or rank-deficient geometry produces an abstention.
No simultaneous rays cross this volume at the current epoch. Increase the array size or choose another ground station.
Perturbed-operator OSSE only—not a field retrieval. Hidden-truth measurements use independently perturbed endpoints, path geometry, and gain before TV-ART inverts the nominal exact sparse ray–voxel operator. Validation holds out complete station groups. Opacity is relative ray-path exposure; the display error proxy is not posterior covariance. The local ENU corner sag is 0 m against this coarse OSSE's explicit 0 m limit. Production inversion accepts calibrated external observations only and rejects unsafe tangent-plane domains.

MODEL ASSURANCE interactive-rf-v4
component-verified simulation with a perturbed-operator OSSE. FIELD VALIDATION NOT EVALUATED. Not for operational use.
Policy interactive-rf-field-acceptance/v1 · No synchronized calibrated field-validation package has been ingested. Research simulation—not a live atmospheric retrieval instrument. SGP4 public mean elements drive geometry; public weather cover is converted to explicitly heuristic liquid-water scenarios. Catalogs omit the synchronized payload, antenna, clock, beam, polarization, and receiver-calibration telemetry needed for coherent RF inference. The interface therefore reports path coverage and synthetic fit diagnostics, never field-validation claims.
