I have designed this GUI to make finding ICAO METAR's as fast and easy as possible. AP Weather is simply an ICAO browser which accesses NOAA's website using a built-in ICAO database. I will add updates as ICAO station codes dramatically change.
The list of ICAO stations is always changing. I have compiled NOAA's latest list with other resources I have found on the internet while removing some stations that never seem to report any data. There are some locations, like Iowa, that have numerous stations that do not report. In some cases, I have left these for ICAO ID reference only. You can always manually enter the ICAO by touching the text entry field. Remember to use all caps.
ICAO weather data (METAR) is provided by NOAA's public domain server. You can access this information though the internet by going to: http://adds.aviationweather.gov/metars/
The METAR information is only as accurate and up-to-date as provided by NOAA at the time of request. A P Weather reads the text files of NOAA's archive so the data you receive will be the last report filed by the station. If NOAA hasn't received an update from a station for a while, the METAR will NOT be accurate. You will find many stations that have no data at all and some that have not been updated for as long as a year.
When you get the report, look for the time stamp to verify its accuracy.
I have included a link to NOAA's TOC METAR server at the bottom of each station report so you can access it to verify results and get more information without closing AP Weather.
The satellite images are infrared images from the 11 micron channel of the geostationary satellites including; GOES-east, GOES-west, GMS, Meteosat satellites, NOAA-15, NOAA-16, and NOAA-17. The higher clouds are colder and appear white in the "B & W" maps and green and blue in the "Color" maps. The ground temperature is warmer so it appears black in the "B & W" maps and red in the"Color" images.
These images have been remapped and combined into a mosaic by NOAA and are generated every 30 minutes. They are time stamped in the upper left corner. Further information on weather satellites and available images can be obtained from NESDIS at http://www.goes.noaa.gov/
There are over 5,000 locations stored on the scroll wheel. This is too many to "finger scroll" so I added a fast forward and rewind button for each side of the wheel. The buttons skip entries proportionally to the length of the list. On long lists you will skip large numbers of entries and on small lists you my not skip any. (The buttons are disabled on lists less than 10 entries long.)
