Wmleler and DaculaWeather - Here is the response I got from NWS about Ridge 2 products.
Q1: Is Ridge2 ready to be used by the public? Is there any sample code they can provide that accesses the new Ridge2 radar?
A1: Ridge is still in experimental mode. Though that means it's available to the public, things will likely still change. So, do consider that as you're writing any code.
Q2: How do we access the Ridge2 image files? I have found this link
http://radarcache.srh.noaa.gov/tc/tc.py/1.0.0/ridge::NAT-N0Q-201209131710/4/3/6.png but it doesn't help me figure out how to really access them.
A2: The URL you give above, is the address to part of a radar image as served by a tile server. The last 3 integers indicate its position in the google grid (left, right, zoom, essentially).
Q3: Are there other ways to access the images, like a tile server or other server? Is there any documentation on what is available?
A3: Though it's not well-documented at this state in development, the js in the page (which is you can see pretty easily in the directory:
http://www.srh.noaa.gov/ridge2/ridgenew2/js/)
They also said "once Ridge2 becomes the official radar Ridge (one) images on
http://radar.weather.gov/ridge/RadarImg/ will remain up and running for a couple of years".
