Moreover, as Cowtan & Way (2013) demonstrated, even the short - term slowing of global surface temperatures was largely an artifact of poor Arctic
temperature station coverage.

Penn Station coverage [Curbed]
The calculations between the two agencies differ only slightly, as NASA's calculations are extrapolated to account for polar locations with
poor station coverage, while NOAA relies more heavily on the polar station data.
Although station coverage varies spatially and temporally, there are adequate stations with decadal and century periods of record at local, regional, and global scales.
The width of each year's curve reflects the uncertainty in the annual temperature values (caused by factors such as changes in measurement techniques and the fact that some parts of the world have more
sparse station coverage).
National Grid has warned that there has been a significant increase in the risk of electricity shortages and brownouts this winter after fires and faults knocked out a large chunk of Britain's shrinking
power station coverage.
Interest was especially high this particular December because a race was on: since mid - to late summer, the scientists in all three groups had been telling their friends and acquaintances, including those in the news media, that 2005 might turn out to be the warmest year on record — since about 1880, that is,
when station coverage first became global enough to permit a meaningful estimate.
The anomalies are computed back to 1910, the approximate date by which all continents have
station coverage sufficient to resolve values at the regional scale.
Kevin Cowtan and Robert Way later published an important paper showing that much of the slowed global surface warming was an artifact of poor global
temperature station coverage, mainly in the Arctic.
Since one of those areas with
no station coverage is the Arctic Ocean, (which as you know has been warming up somewhat), that puts in a growing difference between the products.

What is perhaps more important is if the reduction in station numbers reduces «
station coverage» — the percentage of the land surface with at least one station within «x» kilometres of that location.
The gridded data span much of Europe, but no estimates of the parameters are produced in areas where
the station coverage is too sparse.
In addition to being a result of cherry picking and largely an artifact of a lack of Arctic temperature
station coverage, Dessler pointed to:
