owned by our user community. The station owners upload their data to
us, which we then archive and display to the general public via web
applications. Without centralized planning, this network has grown to
cover most of the US and is starting to develop a global presence.
Developing an ingest/archival system that can accomodate a large
number of rapidly updating observations has been an interesting
technical challenge. Since the network is composed of heterogenous
hardware sited using different approaches, this poses special issues
for quality control. In this paper we will discuss how we addressed
these challenges and also the lessons learned in working with our
community of station owners.
