NOAA has deleted the files referred to in this post, the ones that were previously archived in this directory
ftp://ftp.ncdc.noaa.gov/pub/data/ushcn/OtherIntermediates/ , and ones that were required to reconcile the former GISS results. If anyone has a copy of the SHAP file, I’d appreciate it.

#97 Roger. Over time, as the darkened snow heats more than the other, won’t the darkened (carbon particles) snow tend to sink more, and become less heat absorbing as it sinks, as it is no longer exposed to the suns rays?

Re #83 on climate alterations .
Science News – 9/1/2007, page 141 Has a brief article about Greenland receiving some soot from Canadian wild fires. However, the amount increased around 1850, when mills and power plants in CXanada and elsewhere in Northern Hemisphere began burning lots of coal.
Industrial soot fell at its greatest rate between 1906 and 1910, causing the darkened snow to absorb about eight times as much solar radiation as it would have if free of soot. The change in energy balance warmed the snow and influenced climate.
More recently, changes in regulations and technology have significantly reduced emissions of industrial soot. However, in the past few decades, Arctic snow has on average absorbed about 40% more solar energy than it did before the Industrial Revolution – see Sept 9 Science.

So was my response (meant to be general in nature), _Jim, try not to be so testy.

Quite a lot, actually.

Please; my comment was related to what ‘they’ could see over the continental US or Canada (AS the signal from said Woodpecker was receivable quite easily stateside) given primitive (by today’s standards) technology; the RADAR equation pretty much spells out the paramters to obtain a given signal strength of a certain value before the application of S/N improvement techniques (like pulse compression, alluded to earlier when I cited ‘chirping’).

These replies are meant to be general in nature, relating back to ClimateAudit topics of discussion (I believe any number of us have easy access to such works as Skolnik’s (NOTA BENE: his “RADAR Handbook”) so perhaps we should lay low on further discourse on this subj).

OTH (Over the Horizon) HF (High Frequency meaning shortwave as on 3 – 30 MHz) RADAR; unsure of its exact purpose or what exactly they could see (pull out of the mud so to speak with any received signals they picked up) as the years during which this was in service was quite awhile before easily-implemented DSP techniques

Quite a lot, actually. The original successful OTH early warning radar had a transmit array in Rome, NY, and a receive array in Maine. It was put in place in 1955. From the wiki:

The USAF’s Rome Laboratory had the first US success with their AN/FPS-118 OTH-B. A prototype with a 1 MW transmitter and a separate receiver was installed in Maine, offering coverage over a 60 degree arc between 900 to 3,300 km.

They could detect missile launches, bombers, etc. Quite a useful beast. Now they are used primarily for other things, such as NOAA modeling ocean currents/wind patterns.

Kwinkidentally, I just wrote a proposal for developing orthogonal waveforms for multiple-input, multiple-output (MIMO) radar, particularly for use in OTH radar. The original systems all used the same waveform, generally a frequency modulated continuous wave.

FWIW, the Wikipedia article on the Soviet Woodpecker

Having lived a good bit of that period, having also endeavored in parallel if not directly in identical ‘fields’ in some cases, underscored with a technical (engineering) background to boot … I like to rely upon my own knowledge base as a ‘check’ on anything else that happens to drift my direction in the way of anecdotes, stories, accounts (call it auditing, if you will, keeping the discussion in line with the purpose of this site); not everything one reads on Wikipedia (or the internet) is authoratative, right true *or* complete.

Lacking here now, in any discussion of the Woodpecker are accounts that would have discussed ‘it’ at the time it was taking place in ham publications e.g. as QST, 73 Magazine; discussions such as DFing the source of the pulses (to provinces of the old USSR).

(As an aside, I imagine an assembled fleet of SAC B-52 bombers would have had quite a signature on ‘the woodpecker’, as did the daily readyness flights the 52′s particiapated in back in those days as part of the nuclear triad that was monitored: missiles, subs, airborn delivery platforms.)
