DATA
The following NOAA CoastWatch ERDDAP dataset metadata explicitly permit free
use and redistribution. Data are supplied without warranties and are not
intended for legal use. No agency endorsement is claimed.

NOAA/NCEP GFS, distributed through PacIOOS and NOAA CoastWatch:
https://upwell.pfeg.noaa.gov/erddap/info/ncep_global/index.html
10m wind components, 2m temperature, precipitation rate, sea-level pressure,
and 2m relative humidity. Approximately 1-degree samples; forecast valid time
is selected near the current UTC time. Kelvin is converted to Celsius,
wind m/s to km/h, pressure Pa to hPa, precipitation kg/m2/s to mm/h.

NOAA CoastWatch Caribbean / NOAA AOML geostrophic currents:
https://cwcgom.aoml.noaa.gov/erddap/info/miamicurrents/index.html
Satellite-derived geostrophic u/v components, approximately 1-degree samples.
Coverage approximately 64.7S–64.7N; not a complete wind/tide-driven flow model.

NASA JPL MUR analysed sea-surface temperature, NOAA CoastWatch distribution:
https://coastwatch.pfeg.noaa.gov/erddap/info/jplMURSST41/index.html
NASA JPL MUR anomaly, NOAA CoastWatch processing/distribution:
https://coastwatch.pfeg.noaa.gov/erddap/info/jplMURSST41anom1day/index.html
Anomaly uses a 2003–2014 seasonal reference; recent values can be revised.
Both are sampled at approximately 1 degree for this global overview.

NOAA WaveWatch III, PacIOOS / NOAA CoastWatch distribution:
https://upwell.pfeg.noaa.gov/erddap/info/ww3_global/index.html
Significant wave height; approximately 1-degree samples, 77.5S–77.5N.

Clouds view: NOAA / NCEP GFS Total_cloud_cover_entire_atmosphere (%).
Public model data served through the University of Wisconsin THREDDS mirror:
https://thredds.aos.wisc.edu/thredds/dodsC/grib/NCEP/GFS/Global_0p25deg/Best.html
The 0.25-degree model is sampled at 0.5 degrees and interpolated for display.
Cloud cover is a model estimate through the atmosphere, not satellite imagery.

Retained legacy NASA GIBS / Terra and Aqua MODIS satellite adapter (not the Clouds view):
Layers: MODIS_Terra_CorrectedReflectance_TrueColor,
MODIS_Aqua_CorrectedReflectance_TrueColor, MODIS_Terra_Data_No_Data,
MODIS_Aqua_Data_No_Data. Images and masks share one dated UTC day, with
an additional day allowed for processing. Missing coverage reveals the
base map. The outer Mercator rows are transparent at the polar limits.
No cloud-cover percentage or other measurement is inferred from RGB.
Official coverage mask definition:
https://gibs.earthdata.nasa.gov/colormaps/v1.3/MODIS_Data_No_Data.xml
We acknowledge the use of imagery provided by services from NASA's Global
Imagery Browse Services (GIBS), part of NASA's Earth Science Data and
Information System (ESDIS).

NASA imagery generally is not subject to copyright in the United States;
this scientific imagery is used with attribution and without implying NASA
endorsement. No NASA logo, commercial satellite imagery or recognisable
person is used. The provider's colour scale is retained. Daily imagery is
fetched for the latest available complete day, with gaps left transparent.

DISPLAY AND ACCESS
Data are retrieved when a layer opens or is refreshed. Numerical datasets
are cached in page memory for 15 minutes. The site's same-origin service retrieves global JSON datasets from NOAA
ERDDAP and caches them for 15 minutes; it sends no device coordinates. The data's actual
valid timestamp is displayed; older data are flagged. Interpolated values
are approximate. Missing values are not filled with zero. Motion is
accelerated and illustrative of the vector field, not real-time travel.
A global overview is not a local forecast, navigation aid or warning service.

The renderer uses original WebGL shaders with a Canvas fallback. Scalar values
are bilinearly interpolated on the GPU, with valid-neighbour renormalization
and a soft coverage edge. No-data cells are never treated as physical zero.
D3 supplies projection/coastline geometry; trails integrate source u/v components.
At source outages, previously loaded numerical grids may remain available for
up to 24 hours from retrieval, explicitly labelled with the unchanged valid time.
The official PacIOOS OPeNDAP service is a model fallback with dynamic available
time discovery. NOAA mirrors may redirect to this same upstream host.

EARTHQUAKE REPORTS AND MOTION (added 3 October 2026)
USGS official all_day/all_week GeoJSON summary feeds; checked every minute while
this page is visible. Feed generation times and preliminary/reviewed status are
shown; events may be revised. Only earthquake-type events are mapped. USGS data
are generally public domain unless otherwise noted, with source credit requested.

Marker pulses indicate epicentre locations; they are not seismic wavefronts or
shaking-in-progress alerts. The tsunami screening flag is not used as a warning.

The 10 m wind field is a separately labelled companion overlay on atmospheric
scalar maps and cloud-top imagery. Geostrophic currents accompany ocean surface
temperature and anomaly. These movements do not advect or evolve scalar colors.
WaveWatch III Tdir supplies peak FROM direction. Original crest marks travel
opposite that bearing with illustrative speed; they do not predict arrival time.
Angular bearings are converted to east/north components before interpolation.
Gentle camera rotation is a browsing effect, not time-lapse. Pause/reduced-motion
controls apply across all layers. Data dates remain unchanged by animation.


CITY AND STREET MAPS — added 3 October 2026
MapLibre GL JS 6.4.1 (BSD-3-Clause), self-hosted browser distribution.
Full bundled notices: /vendor/LICENSE.txt
Source: https://github.com/maplibre/maplibre-gl-js/tree/v6.4.1
Public vector map service and style: https://openfreemap.org/
Commercial use is allowed. Terms: https://openfreemap.org/tos/
Attribution: OpenFreeMap © OpenMapTiles Data from OpenStreetMap.
OpenStreetMap data: ODbL, https://www.openstreetmap.org/copyright
Style remains provider-hosted; attribution stays visible at every zoom.
OpenFreeMap provides no SLA; map detail depends on that public service.
Weather tiles are generated locally in a browser worker from the existing
NOAA/NASA data. Reprojection/interpolation and reduced opacity at city zoom
do not increase the underlying scientific resolution.

GLOBAL FIRE DETECTIONS — added 4 October 2026
NASA LANCE FIRMS Suomi-NPP VIIRS 375 m active-fire / thermal anomaly CSV.
We acknowledge the use of data from NASA’s Fire Information for Resource
Management System (FIRMS), part of NASA’s Earth Science Data and Information
System (ESDIS). NASA data are openly shared; reuse follows NASA’s data-use
and citation guidance. No NASA endorsement or logo is implied.

https://www.earthdata.nasa.gov/engage/open-data-services-software/data-use-policy
Rendering, controls, CSV adapter, and observation replay are original project
code on the existing BSD-3-Clause MapLibre renderer. No proprietary fire-map
UI, third-party animation, commercial fire tiles, or NASA logo is embedded.
The same-origin service checks one fixed public global CSV, with five-minute
caching and labelled prior data for at most one hour after retrieval failure.
It sends no visitor coordinates. Source observation and retrieval times are
shown. Low-confidence pixels are excluded by default; users can include them.
Clusters count detection pixels, not wildfire incidents. Nominal 375 m
resolution is not a precise ground perimeter; scan/track footprint varies.
Original animated flame icons highlight locations. Replay reveals acquisition times, not fire
spread, flames in progress, evacuation zones, or predicted arrival. Clear
areas are not an all-clear: clouds, overpasses, and detection limits apply.

The retained legacy cloud-temperature adapter uses NASA GIBS MODIS_Cloud_Top_Temp
colour definitions (checked 4 October 2026); it is not the displayed Clouds layer:
https://gibs.earthdata.nasa.gov/colormaps/v1.3/MODIS_Cloud_Top_Temp.xml
The original XML is retained in the source checkout. Text values describe
the exact displayed pixel's published colour bin, not raw sensor values.
Unknown, blended or partially transparent colours are not decoded.
