Sentences with phrase «urbanized stations»

We identified the most highly urbanized stations in terms of associated population and night - light brightness.

Having said that, we saw in Section 2 (Figures 12 & 13) that the highly urbanized stations are significantly affected by urbanization bias, with the bias introducing a warming bias of roughly 0.7 °C / century.

When a sample of highly urbanized stations was tested, the adjustments successfully removed warming bias for the 1895 - 1980 period, but left the 1980s - 2000s period effectively unadjusted.

Where are the plots of trend for urbanizing stations versus non-urbanizing?

Not exact matches

As the areas around the weather stations became urbanized, this would have introduced an urban heat island at the station.

This is because many of the world's weather stations are currently in urbanized areas, but in the late 19th / early 20th centuries, these areas were rural (or at least less urbanized).

As a result of this extra urban warmth, if a weather station becomes urbanized, this introduces an artificial warming bias into the station's record, i.e., urbanization bias.

Soon, the weather station itself becomes urbanized (1980 - 2010).

Indeed, if we use NASA's satellite measurements of the average night - time city lights as an estimate of the amount of urbanization in the area, then we can see from Figure 31 that the station is right in the middle of a very heavily urbanized area.

In addition, only 99 of the stations are highly urbanized (in terms of population and average night - light intensity).

If you did that, the way that the amateur deniers think that contaminated data would enter the record — such as stations becoming urbanized, being tampered with, etc — would actually be true.

An even more worrisome result is that the adjustment procedure for one of the popular surface temperature datasets actually increases the temperature of the rural (i.e. best) stations to match and even exceed the more urbanized (i.e. poor) stations... the adjustment process took the spurious warming of the poorer stations and spread it throughout the entire set of stations and even magnified it.

An even more worrisome result is that the adjustment procedure for one of the popular surface temperature datasets actually increases the temperature of the rural (i.e. best) stations to match and even exceed the more urbanized (i.e. poor) stations.

If two stations warm due to increasing populations and the 3rd does not, the 2 «urbanized» stations create a regional expectation for the assumed trend.

Even though most (99 %) of the Earth's surface is not urbanized, some 27 % of the Monthly Global Historical Climatology Network (GHCN - M) temperature stations are located in cities having populations of more than 50,000.

Other notable PHA - detected adjustments are minimum (and more modest maximum) temperature shifts associated with a widespread move of stations from inner city rooftops to newly - constructed airports or wastewater treatment plants after 1940, as well as gradual corrections of urbanizing sites like Reno, Nevada.

to select sites that haven't changed over that time period, all they are claiming is that once a station is urbanized, then the UHI doesn't increase very much.

With one Indian city already installing composters at every police station, it seems composting could play an important role in a strategic approach to this rapidly urbanizing country's waste challenges.

Such a phenomenon has been observed at urban stations whereby once a site has become fully urbanized, its trend is similar to those at surrounding rural sites.
