Sentences with phrase «larger than the satellite data»

Not exact matches

The retreat of sea ice in the Arctic Ocean is diminishing Earth's albedo, or reflectivity, by an amount considerably larger than previously estimated, according to a new study that uses data from instruments that fly aboard several NASA satellites.

First detected in 2003, the 2,500 square - mile hot spot was confirmed by NASA satellite data in October 2014, and is said to be responsible for producing the largest concentration of methane in the U.S., and is more than triple a standard ground - based estimate.

The trends in LW and SW are larger than the trend in NET, but it should be noted that getting decadal trends out of satellite data of this sort is difficult.

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.

Large variability reduces the number of new records — which is why the satellite series of global mean temperature have fewer expected records than the surface data, despite showing practically the same global warming trend: they have more short - term variability.

The difference of adding 1998 is greater here than with the surface data, because the response of tropospheric temperature to ENSO is twice as large as that of surface temperatures to ENSO (in other words, the 1998 anomaly is much larger in the satellite data).

Various methods collect data at different scales: Chamber measurements collect data over square - meter areas, tall towers and aircraft observe larger areas, and satellites (e.g., Greenhouse Gases Observing Satellite, or GOSAT) observe areas larger than a square kilometer.

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.»

That stubborn error in the satellite data is about six times larger than what is scientifically possible, and several times larger than the effect scientists are trying to see, namely planetary warming caused by continued massive emissions of carbon dioxide into the atmosphere.

or does it mean that the potential errors are large enough to permit Paltridge's NCEP data to be a better representation of reality than the layer separated data derived from the satellites?
