In addition to the surface data described above, measurements of temperature above the surface have been made with weather balloons, with reasonable coverage over land since 1958, and from satellite data since 1979.

This involves a combination of satellite observations (when different satellites captured temperatures in both morning and evening), the use of climate models to estimate how temperatures change in the atmosphere over the course of the day, and using reanalysis data that incorporates readings from surface observations, weather balloons and other instruments.

At face value, the satellite data is supported by weather balloon data, covers a much larger area of the globe than the surface - based data, and, as you pointed out, is free from the urban heat island effect and other potential flaws of surface measurements.

None of these reanalyses directly use the surface temperature data so their returned surface estimate is a combination of a state of the art data assimilation scheme and much of the rest of the surface observing system (satellites, weather balloons, surface pressure, sea surface temperatures, etc.).

The same issues have dogged other attempts by climate scientists to glean clues on climate trends from bodies of data collected by satellites and weather balloons for other reasons (not to mention ongoing attempts to discern climate patterns in tree rings, ice layers, and other natural substitutes for thermometers; remember the «hockey stick» debate?).

Both the Microwave Sounding Unit (MSU) satellite (analyzed by the University of Alabama in Huntsville by John Christy and Roy Spencer) and weather balloon data (trends reported by a number of researchers, notably Jim Angell at NOAA) have failed to show significant warming since the satellite record began in late 1978, even though the surface record has been rising at its fastest pace (~ 0.15 C / decade) since instrumental records began.

The year 1979 saw the launch of the first temperature - gauging satellites, and suddenly we were not limited to data from ground stations, sea buoys, merchant vessels, and weather balloons.

I think the data collected by millions of weather balloons shows the absence of the hypothesized «tropical hot spot».

To measure the thermal winds, they studied data on the motion of weather balloons at different altitudes in the atmosphere.

Well, there are a series of now infamous graphs and studies which actaully «hid» the long term temperature data which supported the weather balloon results.

Citing the work of Dr. John Christy and Richard McNider at the University of Alabama in Huntsville (UAH), which compared climate model projections with temperatures measured independently by satellites and weather balloons, he said «the average warming predicted to have occurred since 1979 (when the satellite data starts) is approximately three times larger than what is being observed.»

The satellite data and the weather balloon data are the best evidence we have of whether warming is occurring, and that evidence demonstrates that it is not.

We carried out new laboratory experiments, and analysed the data from millions of weather balloons, to calculate exactly how much global warming carbon dioxide was causing.

It also considers the use of weather balloons to provide a wealth of upper atmosphere data.

The most astounding thing to that viewer was the amount of hard evidence presented, especially the number of weather balloons and Argo buoys that collected data.

They are most commonly used by being lifted up through the atmosphere by a weather balloon — data sets compiled from parts of this data are often referred to as the «Balloon Record&balloon — data sets compiled from parts of this data are often referred to as the «Balloon Record&Balloon Record».

The lamestream climate scientists are still trying to malign the weather balloon data after dozens of years of data!

So, we decided to analyse weather balloon data in terms of a molecular property known as the «molar density».

As each of the weather stations launches between 1 and 4 balloons per day, and has an average of about 36 years worth of data, this makes for a lot of data.

We downloaded weather balloon data for the entire North America continent from the University of Wyoming archive.

Because the satellite data measure an average temperature through a depth of several kilometres in the atmosphere, they would be expected to compare better with upper - air measurements taken using weather balloons and radiosondes than they would with measurements at the surface.

I do not know the accuracy of the NCEP reanalysis data on upper tropospheric humidity, but the direct measurement of humidity by weather balloons seems preferable to the very indirect determination from satellite data.

«We expected about 50 percent stronger response in the atmosphere because of El Nino,» Karl told reporters, explaining that there was «very little response in the satellite and weather balloon data.»
