Default Need free temperature data for specific location

I am looking for temperature data for Asheville, NC. What I need
is the daily low temperatures from November 1st to April 1st, going
back how ever many years the data is available.

See my post here subject: "Need graph - avg of coldest 10% of
recorded temps for each day for location" posted on 10/17/2009.
Nobody could recommend a site that had something similar to what I
need - so I apparently will have to make my own.
I wanted a graph of the coldest 10% (or maybe up to 20%) of the
data to get an idea of how cold it could get (reasonable possibility)
during those months. (If the data goes back 80 years, then the point
for each day would be the average of the 8 coldest days on record.)
If I make my own graph, I will probably exclude the coldest 2 days on
record for each day, and then take the coldest 10% from whats left.

I know http://weather-warehouse.com will provide a spread sheet
of the data (more data than I want) for Asheville (the station closest
to downtown) going back many years, but they want $210 for it. I also
could get it a day at a time from almanac.com - but for 80 years that
would be 12,000 manaul queries.

Thanks for any help.

You will not get 'the big picture' using the technique above
Here are two problems with it.

1) Asheville is not the globe. To measure GLOBAL warming
one needs many stations distributed across the Earth.

2) One does not use extrema to find trends. That is a statistical
fallacy. Try linear regression.

Why not say why you need it, depth to make
a foundation footer, or sizing a central air system?

Check the record high and low box and see a
great interactive graph.

2) One does not use extrema to find trends. That is a statistical

If that data was available for Asheville I -might- look at it closer
to see if it would help - if the data I need is unavailable. If I
had the data I described I wouldn't need to use statistical
probabilities - I would just average the coldest 10% of the data.

I am not interested in trends. I am interested in a long-term
reasonable worst-case scenario (cold). (Not a record setting/matching
worst-case scenario - that is available.) I am not using extrema. I
said I'm dropping off the two coldest days on record, and then
averaging the bottom 10% that's left (for each individual day).

Where can I get the data - the lows for each day going back many
years?

Well, it might get to be 20 below F, that would be
an all-time record by 3 degrees, but what the heck,
it is a reasonable worst-case scenario.

I was in 20 below near Lake Erie in 1962, and
thought that would be the coldest I would see, but in
1996, 300 miles farther south, it got to 22 below F.

There isn't much about weather that can be
predicted months ahead of time.

I'm looking for a source of weather data. You work without data?

These data cover the years 1874-2005. The number of years on
Each station's record varies and is presented in the last column
of this table. These "Filnet Value" data were corrected for:
- outliers 3.5 SIGMA beyond the mean (replaced by estimates),
- time of observation bias,
- the change from liquid to electronic thermometers, and
- vertical station moves.


The second column of the table is the probability of non-zero
correlation F-statistic. Numbers near zero indicate weak trends,
while numbers at, or near, one mark strong trends.


These data were found at:ftp://ftp.ncdc.noaa.gov/pub/data/ush...ata.Zftp://ftp....
The valid, or non "-99.99," yearly average fields from mean "Filnet
value," or "3A," records in years later than, or equal to, 1800 are
used.


is the daily low temperatures from November 1st to April 1st, going
back how ever many years the data is available.


See my post here subject: "Need graph - avg of coldest 10% of
recorded temps for each day for location" posted on 10/17/2009.
Nobody could recommend a site that had something similar to what I
need - so I apparently will have to make my own.
I wanted a graph of the coldest 10% (or maybe up to 20%) of the
data to get an idea of how cold it could get (reasonable possibility)
during those months. (If the data goes back 80 years, then the point
for each day would be the average of the 8 coldest days on record.)
If I make my own graph, I will probably exclude the coldest 2 days on
record for each day, and then take the coldest 10% from whats left.


I knowhttp://weather-warehouse.comwillprovidea spread sheet
of the data (more data than I want) for Asheville (the station closest
to downtown) going back many years, but they want $210 for it. I also
could get it a day at a time from almanac.com - but for 80 years that
would be 12,000 manaul queries.


Thanks for any help.


You will not get 'the big picture' using the technique above
Here are two problems with it.


1) Asheville is not the globe. To measure GLOBAL warming
one needs many stations distributed across the Earth.


2) One does not use extrema to find trends. That is a statistical
fallacy. Try linear regression.


If that data was available for Asheville I -might- look at it closer
to see if it would help - if the data I need is unavailable. If I
had the data I described I wouldn't need to use statistical
probabilities - I would just average the coldest 10% of the data.


I am not interested in trends. I am interested in a long-term
reasonable worst-case scenario (cold). (Not a record setting/matching
worst-case scenario - that is available.) I am not using extrema. I
said I'm dropping off the two coldest days on record, and then
averaging the bottom 10% that's left (for each individual day).


Where can I get the data - the lows for each day going back many
years?


Just take a look here for lots of actual and older Asheville data.

Maybe this helps you.


It looked very promising. I got to the 3rd window, with the data I
wanted selected (Asheville daily mins 1902-now), and then it said the
price was $200. (The source I 1st mentioned was $210.)
