Programmers
 

Does anyone know of a (preferably free) web service that provides METARs?

Eg: http://weather.noaa.gov/pub/data/obs...tions/KBOS.TXT

Tom,

Metars
 

I read them into one of my programs from this XML site:
http://weather.aero/dataserver_curre...tars.cache.xml

I use the METAR desktop gadget for windows. Microsoft has removed the gadget gallery (the link says in preparation for Windows 8) but you can still find gadgets online. I found it on this link: http://www.thoosje.com/vista-sidebar...ilities-3.html, five rows down on the right. I think the programmer does not actively support it anymore but it has worked flawlessly for several years. You can configure it with your nearest local reporting station and then clicking it will bring up the latest METAR for that station, decoded, along with a radar image and 7-day forecast. There are links in the report that will open a web browser to give you animated radar or find weather for a different location.

Notams
 

I am looking for something similar to this in XML for Notams

Web Service Registration
 

Perhaps this link will provide what you are after...

Thanks all. I'll let you know what I come up with.
