That's not a good option for bad weather depending on the region. Rain fade and other effects at 24Ghz and above can hinder a set of links, which is sometimes better than having no links at all. The encoding and error correcting capabilities play a crucial part in having a good connection.

In addition to RSVP or may be worth using minimum modulation settings on the radios if possible. IE so that links completely drop and you re-route rather than run with less bandwidth.

Auto-bandwidth won't help here if the bandwidth reduction is 'silent' as stated in the first message. A 1G interface , as far as RSVP is concerned, is a 1G interface, even if radio interference across it means it's effectively a 500M link.
Jason also explained the TWAMP + latency solution, which is an active solution and doesn't rely on operator or automatic bandwidth providing information, but network automatically measures latency and encodes this information in ISIS, allowing automatic traffic engineering for LSP to choose the lowest latency path. I believe Jason's proposal is exactly what OP is looking for. -- ++ytti
