kWx vs FYRAVUE

Minimize bandwidth and eliminate third-party data collection by directly asking official NOAA weather stations, which include many Canadian and Mexican stations. You can add/ rearrange /subtract from the list. kWx retrieves data directly from weather.gov. Get the current conditions and temperature for most airports and then get the 7-day text forecast for those stations, or offset the forecast location from the weather station, e.g. use KNUQ (Moffett) for current temperature but set the latitude and longitude of Cupertino for the 7-day forecast. This is how NOAA reports the weather for any location. On the list page a station that has an asterisk means the forecast location is different from the weather station or you can rename that station to the actual location. Sometimes data are missing from weather.gov but available from aviationweather.gov (the FAA). These data are used as backup. On the Add station screen you can click the "Get Location" button and using your favorite mapping app you can enter in the location for where you want the forecast to be from as well as naming the station. Find Station button links to new page that allows you to see all the stations for each State and Canadian Province. If the corrected lat/lon offset is within 0.02 degrees the asterisk is omitted. Most stations are K+ Airport Locator (e.g. KORD), but Alaska/Hawaii begin with PA/PH, and Canadian stations begin with C. Many Canadian stations are C+Airport Locator (e.g. CYVR for Vancouver) but others begin CW, CX and CZ. In-app lookup for both US and Canadian weather stations. If available the Heat Index (combination of temperature and humidity) is presented. A heat index below 105F is in yellow, below 125F in orange, above that in red. ~40 Mexican stations are available, all start with MM rather than K (US) or C(Canada). No forecast for the Mexican stations, just current weather. Most foreign airports have now been added. Enter the ICAO code and aviationweather.gov will return the current temperature, conditions and winds for that airport. ICAO codes are different from IATA codes, which are typically 3 letters. ICAO codes are 4 letters and info about the region the airport is based in. All existing US weather stations (e.g. KORD) are ICAO codes but overseas they tend to be more obscure, eg Heathrow, which has an IATA code of LHR, has an ICAO code of EGLL, Narita is RIAA, CDG is LFPG, Seoul is RKSS, etc. The webs are pretty good at coming up with the right ICAO code for a given airport. Note that there is no forecast within these data, just the current conditions. We are tapping into METAR data for each airport. Try it and see! The app requires iOS 15

FYRAVUE helps you keep track of satellite-detected fire activity and modeled air and smoke data worldwide. Explore events on the map, save places that matter to you and see how current the displayed data is. What FYRAVUE offers: • Worldwide fire map: Nearby satellite detections are grouped into clear events. Heat intensity, regions and filters help you understand the data. • Satellite view: Explore the surroundings of a fire detection from above. Imagery provides geographic context, may be older and does not necessarily show a visible fire. • Clear air data: PM2.5 pollution, other pollutants and smoke indicators are presented separately, with units, timestamps and information about their model basis. • Your places in focus: Save places or use your current location. Set a radius from 5 to 250 km and choose your own PM2.5 alert thresholds for each place. • Local notifications: Get notices about newly detected thermal activity and confirmed PM2.5 alert levels. Repeated downloads do not count as new confirmation. • Fire data offline: The last valid fire dataset is retained for up to 72 hours. Map tiles and satellite imagery are not included in this offline cache. • Widgets: View fire detections, PM2.5 and smoke AOD for selected places on your Home Screen and Lock Screen. The different measures remain clearly separated. • Focused navigation: Compact map information, favorites, structured fire regions and light and dark map styles. Understanding air data Low PM2.5 pollution means less modeled fine-particle pollution, not low air quality. The PM2.5 rating is not an overall assessment of all air pollutants. Smoke AOD describes the optical thickness of the atmospheric column, not the air you breathe at ground level. Missing or outdated values are identified. Notifications in context Analysis of watched places and notifications run locally. iOS controls background and widget updates; fixed check intervals and real-time alerts are not guaranteed. Missing or disappearing satellite detections do not confirm that an area is fire-free or that a fire has been extinguished. Data sources and limitations FYRAVUE uses NASA LANCE FIRMS data and modeled atmospheric data from the Copernicus Atmosphere Monitoring Service. Thermal anomalies are not individually confirmed fires. Satellite and model data may be delayed, incomplete or inaccurate. The app is not an official warning, health or evacuation system. Always follow local authorities in an emergency. No account required. Location and notification permissions are optional. The app contains banner advertising; the map view remains ad-free.
