The primary reason for creating this new version was that the old version became difficult to manage as more and more cameras got installed. Specifically in the old version changes to its many files had to be done by hand, while the new version uses a few simple (currently spreadsheet) configuration files from which its thousands of HTML/web pages get generated or installed.
A currently incomplete set of KML files is also being generated from those spreadsheets to show HPWREN sensor and network attributes in Google Earth. This allows real-time data to be displayed in Google Earth. The columns sticking up, visible when rotating the image, show the wind speed (height) and wind direction (the more towards red, the closer to NE wind, to get a quick view of Santa Ana-ish conditions). Those towers are clickable for all the met data from that site.
Other changes include:
The old cameras web page is still around but not linked in and can be restored if need be. The new one may also change over time.
