Re #96 MrPete

Rain in Seine … I think I have read all CA posts for the last 2 years (E&OE) and enjoyed Maine. That is, if it is possible to enjoy bad science, errors going neglected and the rest of the lessons therein.

Re 99 Steve McI

My email is sherro1 at optusnet dot com dot au

If you are prepared to mail me a postal address I will try to remedy that shortage.

Regards Geoff.

#97. Nope. I asked BoM for data quite a few months ago, but got no response.

#91 I think You are confusing Chathams with some other island (Stewart?). Chatham Islands are on the Chatham Rise about 800 km almost due east of Christchurch, i e just north of the middle of the South Island. A fairly good analogue would be using data from Bermuda to correct the record for Washington DC.

Re # 95 MrPete

It’s not the value of a change that I’m referring to, it’s the fact of a change. I do not know the answer to this, but if a new calculation for (say) satellite calibration adjusts a distance, does this mean that the whole GISS system is adjusted? There has to be some reason for the frequency of adjustments.

Re # 96 Steve McI, let me know if you already have the public CD of some 1200+ Australian B o M stations. The CDs are the best means I know for getting ROW data from here.

81,92. What I’m inteested in in is Antony Wtts type detailed informatino on the stations and details on station history, if they can be obtained from the NZ meteorological service or elsewhere.

Geoff,

Even with a new reference frame, the rain in Maine falls mainly on the Seine.**

It’s an interesting paper. However, I seriously doubt any of this would impact climate calculations. Grid adjustments in the paper would be pure “bit noise,” below climate measurement detectability.

Grid adjustments in the paper are all much smaller than an arc-second (30m or so); climate location measurements are not that precise.

More significant: even with reference frame adjustments, distances change much less than do positions.
