NOAA's premiere
surface temperature
reference network
shows little warming
since 2005.
Here is NOAA's
( U.S. Commerce Dept. )
proud description of
their United States
USCRN weather
station network,
from their website:
"The contiguous U.S.
network of 114 stations
was completed in 2008.
There are two USCRN stations
in Hawaii and deployment of
a network of 29 stations in Alaska
continues.
The vision of the USCRN program
is to maintain a sustainable
high-quality climate observation
network that 50 years from now
can with the highest degree
of confidence answer
the question: How has the
climate of the Nation changed
over the past 50 years?
“These stations were designed
with climate science in mind.
Three independent measurements
of temperature and precipitation
are made at each station,
ensuring continuity of record
and maintenance of
well-calibrated and
highly accurate observations.
The stations are placed
in pristine environments
expected to be free
of development
for many decades.
Stations are monitored
and maintained
to high standards
and are calibrated
on an annual basis.
In addition to temperature
and precipitation,
these stations also measure
solar radiation,
surface skin temperature,
and surface winds.
They also include
triplicate measurements
of soil moisture and
soil temperature
at five depths,
as well as atmospheric
relative humidity
for most of the
114 contiguous
U.S. stations.
Stations in Alaska and Hawaii
provide network experience
and observations in polar
and tropical regions.
Deployment of a complete
29-station USCRN network
in Alaska began in 2009.
This project is managed by
NOAA's National Climatic Data Center
and operated in partnership with
NOAA's Atmospheric Turbulence
and Diffusion Division.”
