Northern hemisphere ozone receives little attention.
Fairly recently a partial view of the north has become available, still incomplete, model output, nevertheless this might be eye opening.
The images used here are from NASA  are tilted partial northern hemisphere. Image left here is making the geography clear, barely makes the Mediterranean, southern US or Japan.
Fingers of ozone reaching far south has been known for a long time, pre-dates satellites, is rarely mentioned.
Satellite sensing is restricted by how it has to be done: the only proper way is by transmission through the atmosphere, which means from the ground. Reason: measurement uses the difference in absorption between a pair of spectral lines where a light source shining through, daytime the sun, night-time reflected sunlight, the moon, hence remote sensing has no data night side.
Over much of 2013 I have been collecting the extremes for a day as reported by the UK Met Office. April up to 1st December.
Example as copied

Sunniest 2100-2100 6.8 hours Wittering

This might be useful / of interest to a few people so I have processed the information into a flat field spreadsheet form. I considered full Normal form but lets keep things simple, I’ve done the hard part.

I’ve been thinking about what makes the warmist-skeptic fight go on and on. What I have noted is the constant difference in how each side places its emphasis, and that this shows up in its speech. Specifically, the skeptics use declarative, as in “this will”, “this shall” or “this does”, and, of course, its negative equals.
The meteorological station at Armagh Observatory, Northern Ireland closed in 2000. A lot of the data has been made online access via scanned logbooks and some digitised data, paid for primarily by lottery funds.
An unpublished version of the data is used as part of a fractional delay demonstration.
Earlier article providing a template and instructions is
Working code is provided for copying and use, no macros.
Fractional delay means one timeseries can be delayed or advanced in time relative to another by any amount including any fraction of one sample time. This is achieved by a short digital filter (5 taps) which is “designed” by the spreadsheet to user demand.
A demonstration of usage on real data is the next DaedalEarth article. Link to demonstration.
Combining (or merging or whatever you call it) two or more PDF files into a single output PDF is very easy to do without needing to pay for anything provided you can do simple typing.
This contradicts various web advice sites, how-to and so on where surprise surprise the solution is buy this or that.
Unix users, BSD, Linux, OSX probably won’t need telling but the following with slight changes works there too.
I often use Method 2 but for this is horses for courses, why we have a brain.
I’ve written this without assuming the reader is much of an expert, might be talking down.
This is a welcome new facility. Well put together web site.
Figures 1 and 2 are demonstrating both northern and southern hemisphere decay from a Dirac injection of a test signal. The consequent effect is very close to perfectly linear, proportionality between pressure and effect of pressure over more than an order of magnitude of data variation (hence linear law). This seems to destroy IPCC claim of a non-simple law. Deviation is <1%
In addition the effect is a simple low pass filter on all kinds of atmospheric carbon dioxide. A later article might cover this in detail.
Fig. 14 from paper 100 years ago by Anders Angstrom on LWIR emission. This shows families of curves grouped by two different lapse rates.
Note: This Daedal Earth blog article was rapidly produced to make the PDF available for citation elsewhere. Content may change later.
Sub-extract from Smithsonian Miscellaneous Collections, Volume 65, Number 3, published 1915. is A study of the Radiation of the Atmosphere
Physicist Dr Anders Angstrom was the son of physicist Dr Knut Anstrom (radiation instrument inventor) the son of physicist Dr Anders Angstrom after whom the wavelength unit the Angstrom is named. Confusion is understandable.
