What's happened to the Ozone?
Editor: Almost forgotten in the Global Warming movement has been been any discussion about the ozone layer.
The Canadian Community News monitors an international blog of scientists, mathematicians, economists and engineers who communicate on a daily basis regarding a wide range of topics.
From time to time these active researchers send through something of interest to the general public. We'd like to bring you some research results in simple form that were received today from Forrest Mims. It shows the interesting interplay between Scientists, both inside and outside organizations that you recognize immediately.
The lesson is: This is how science progresses. It moves in deliberate steps over time.
I've been measuring the ozone layer here in South Texas most days
since 1989 (see
www.forrestmims.org). My data agrees closely with that from the
series of ozone satellites launched since then--closely enough to have
found errors in 3 of them. (I published the first error in NATURE.) [ED

I notified NASA about this, and the scientist I contacted seemed unaware of this. I requested the global mean for my latitude (29.6 N), and he kindly sent the data (for 30-35 N)
These data showed a 3.5 percent or so decline during the spring of 2008 when compared to the prior 4 years (all OMI data).

This finding would have attracted considerable attention
5 years ago. But now it seems that the ozone layer is of much less
interest than global warming, even though the former is easily measured
and studied and the latter is not.
