Yes, they are ALL available! "All RIDGE radar images are downloadable and all that is needed is the URL."

But! To get to them is a bit complicated and requires a bit of computer savy.

Check out the following link and read it very carefully:

Downloading RIDGE Radar Images

For *older* images, you will need to *carefully* follow Step 3, "Download the individual files" (In your case, steps 1 and 2 do not apply.)

You will need to "plug in" the date and time you're interested in, and your all-important "Radar Site ID" and the type of radar image desired, 'Base Reflectivity', etc.

Hope this puts you on the right trail. If you need help, let me know & we'll puzzle it out together. Aloha!
