Sentences with phrase «number of measurement stations»

We know that the number of measurement stations has been slashed by more than two - thirds around the 1990s, about the same time when temperature showed a strong rise.

This is further complicated by the drop out of a large number of measurement stations.

Not exact matches

The expedition was mandated to gather a number of measurements necessary for the design and conception phase of the station.

Let's suppose this position is correct, but when creating the global average I cut the percentage of rural stations in the measurement network from 75 % to 25 % (sorry don't know the real numbers).

Temperatures aloft can be measured in a number of ways, two of which are useful for climate monitoring: by radiosondes (balloon - borne instrument packages, including thermometers, released daily or twice daily at a network of observing stations throughout the world), and by satellite measurements of microwave radiation emitted by oxygen gas in the lower to mid-troposphere, taken with an instrument known as the Microwave Sounding Unit (MSU).5 The balloon measurements are taken at the same Greenwich mean times each day, whereas the times of day of the satellite measurements for a given location drift slowly with changes in the satellite orbits.

Mears and others said that the satellite measurements should not be taken seriously because they only infer the temperature from measurements of radio emissions by Oxygen molecules - AND - that these final numbers never match actual temperature measurements made over land and water (ground stations as well as radiosonde).

These surface networks have had so many changes over time that the number of stations that have been moved, had their time of observation changed, had equipment changes, maintenance issues, or have been encroached upon by micro site biases and / or UHI using the raw data for all stations on a national scale or even a global scale gives you a result that is no longer representative of the actual measurements, there is simply too much polluted data.

Since then, a growing number of surface temperature measurement stations worldwide, coupled with improved methods for correcting for biases induced through urban heat island effects and other station siting and operational issues, have allowed for the development of accurate global temperature estimates.
