I registered my weather station with AWEKAS today.  This is another online service that aggregates and provides weather data on the Internet.  They have a very simple interface for publishing data so I went ahead and added it.  They come to a URL on a periodic basis that you provide and pick up a small data file with your weather data.  I built a PHP page that returns the weather data in the expected format with a content-type of text/plain.  So the data file is virtual and built on demand.  So far they are receiving my data OK.  There really is no need for me to publish my weather data to so many different sites.  But it’s all part of my enjoyment of the hobby.  Which hobby you might ask?  The weather station, software development, electronics, or abuse of PVC plumbing and conduit?  Definitely some combination of the above.
