Statistics on average days with clear skies needed

Can anyone point me to a website which lists the average number of clear
days (nights would be even better) per year for cities across the USA?

Make Cincinnati about a minus 3.
Clearer skies than here.

There's summary data for lots of US cities -- monthly percentages of
clear/partly-cloudy/cloudy days (sunrise-to-sunset, unfortunately) -- at

http://ols.nndc.noaa.gov/plolstore/p....prodspecific?
prodnum=C00095-PUB-A0001

[you'll need to paste the above URL back together -- no space between
the "prodspecific?" and "prodnum=C00095-PUB-A0001"]

This comes from following the sequence
NOAA online store
http://ols.nndc.noaa.gov/plolstore/p...re.main?look=1

select Climate - Data, Cloud, and hit Continue for list

select Comparative Climatic Data
select Cloudiness - Mean Number of Days (Clear, Partly Cloudy, Cloudy)


A few years ago NOAA offered lots of raw individual-station data for free,
but not any more. For more detailed data you can buy on-line a time-series
hourly observations, including cloud cover, for lots of sites across
the US for $2.00 per site. There's also a CD of hourly observations
for 262 sites, spanning 1990-1995, for $130.00; and three regional CDs
(Western/Central/Eastern) spanning 1961-1990, for $130.00 per CD.

And, for $50 there's a "Climate Atlas of the United States" CD,
spanning mostly 1961-1990. It appears to include daytime cloud cover data.
Not sure whether it offers time-series data (month-by-month or year-by-year)
or only mean&extreme values over the period. Anyway it's described at:
http://ols.nndc.noaa.gov/plolstore/p....prodspecific?
prodnum=C00519-CDR-A0001
[likewise, paste the above two lines together]


There may well be lots of other data sources available. The above just came
from following a link I'd bookmarked a few years ago, which now redirects
to the NOAA on-line store.

Guy Ottewell's "Astronomical Companion" (a wonderful book, not a website)
includes seasonal cloudiness contour maps for the continental US.
