Not exact matches

New measurements of atmospheric loss by NASA's MAVEN probe should help scientists determine how a planet with rushing water and a temperate climate a few billion years ago transformed into a cold, dry desert.

New measurements by NASA's Goddard Institute for Space Studies indicate that 2012 was the ninth warmest year since 1880, and that the past decade or so has seen some of the warmest years in the last 132 years.One way to illustrate changes in global atmospheric temperatures is by looking at how far temperatures stray from «normal», or a baseline.

Results: When it comes to understanding how atmospheric particles affect climate, one measurement can't tell the whole story, especially in areas that haven't been studied.

Find out how researchers are using data from U.S. Department of Energy's Atmospheric Radiation Measurement (ARM) Climate Research Facility — the world's most comprehensive outdoor laboratory and data archive for research related to atmospheric processes that affect Earth's climate — to improving regional and global climate models.

Find out how researchers are using data from the U.S. Department of Energy's Atmospheric Radiation Measurement (ARM) Climate Research Facility — the world's most comprehensive outdoor laboratory and data archive for research related to atmospheric processes that affect Earth's climate — to improve earth system models.

As NOAA's Mauna Loa measurement of atmospheric methane concentrations are only currently increasing at a rate of approximately 0.25 % per year (or 12.5 % change in 50 - years); how could anyone be concerned that the change in atmospheric methane burden in 50 - years could be 300 % (as per Isaken et al (2011) case 4XCH4; which would require an additional 0.80 GtCH4 / yr of methane emissions on top of the current rate of methane emissions of 0.54 GtCH4 / yr)?

Mike's work, like that of previous award winners, is diverse, and includes pioneering and highly cited work in time series analysis (an elegant use of Thomson's multitaper spectral analysis approach to detect spatiotemporal oscillations in the climate record and methods for smoothing temporal data), decadal climate variability (the term «Atlantic Multidecadal Oscillation» or «AMO» was coined by Mike in an interview with Science's Richard Kerr about a paper he had published with Tom Delworth of GFDL showing evidence in both climate model simulations and observational data for a 50 - 70 year oscillation in the climate system; significantly Mike also published work with Kerry Emanuel in 2006 showing that the AMO concept has been overstated as regards its role in 20th century tropical Atlantic SST changes, a finding recently reaffirmed by a study published in Nature), in showing how changes in radiative forcing from volcanoes can affect ENSO, in examining the role of solar variations in explaining the pattern of the Medieval Climate Anomaly and Little Ice Age, the relationship between the climate changes of past centuries and phenomena such as Atlantic tropical cyclones and global sea level, and even a bit of work in atmospheric chemistry (an analysis of beryllium - 7 measurements).

The standard logbook entries made at the time contain no information about how the measurements were taken, so the cause was overlooked, says David Thompson, first author on the paper and an atmospheric scientist at Colorado State University in Fort Collins.

Historical temperature time series and series of atmospheric carbon dioxide measurements show clearly how climate has changed over the past 100 years.

Even if we could discriminate between human - originated CO2 and natural CO2 isotopically with reliability I don't see how carbon isotope measurements could prove we have increased atmospheric CO2 by 40 % anyway (or 110ppm) because, problematically, CO2 has a very short atmospheric residence time.

Also, given the atmospheric CO2 measurements at South Pole range between 246.59ppm - 521.48 ppm I don't see how the trapped CO2 in the ice - core bubbles could accurately represent the back - ground level.

It's early days, but this first real - world measurement of a slowdown in the ocean's ability to dissolve carbon could have worrying implications for those currently thinking about how to stabilize atmospheric greenhouse levels.

Also, while we have good atmospheric measurements of other key greenhouse gases such as carbon dioxide and methane, we have poor measurements of global water vapor, so it is not certain by how much atmospheric concentrations have risen in recent decades or centuries, though satellite measurements, combined with balloon data and some in - situ ground measurements indicate generally positive trends in global water vapor.»

When we analysed the atmospheric water concentration measurements for the balloons, we found that the different slopes in Region 3 depended on how humid the air in the region was, and whether or not the balloon was travelling through any clouds or rain.

Carrying out atmospheric measurements often entails having to consider how representative measurements taken in a single location are, and whether local conditions, such as landforms, affect observations.

It is now contributing to atmospheric (carbon dioxide) concentration,» he said.Using a one million sq. km stretch of forest in Manitoba, Gower and his colleagues coupled their measurements of how carbon moved between the atmosphere and the trees with past records and computer models to examine how the forest's ability to store carbon dioxide has changed since mid-century.

Moreover, since DLR varies widely according to atmospheric conditions, it is very important to achieve enough coverage to be sure that we understand how the localized measurements can be generalized to the global scale.

The standard logbook entries made at the time contain no information about how the measurements were taken, so the cause was overlooked, says David Thompson, first author on the paper and an atmospheric scientist at the State University of Colorado in Boulder.

Currently, many observing systems capture elements of how climate is changing, such as direct measurements of atmospheric and ocean temperature.
