In the new paper, published in the journal Environmental Research Letters, Höglund - Isaksson estimated global methane emissions from oil and gas systems in over 100 countries over a 32 - year period, using a variety of country - specific data ranging from reported volumes of associated gas to satellite imagery that can show flaring, as well as atmospheric measurements of ethane, a gas which is released along with methane and easier to link more directly to oil and gas activities.

Such measurements will probe the atmospheric structure and composition, providing unique information useful not just in the solar system but also in the study of Jupiter - like exoplanets, where no comparable data will be available for the foreseeable future.

Also, it is expected that the technique will be applied not only to astronomy, but also to wide - ranging fields such as spectroscopy, information network systems, atmospheric environment measurement, medical diagnostic technology, and fusion plasma diagnostics.

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.

We find (i) measurements at all scales show that official inventories consistently underestimate actual CH4 [methane] emissions, with the natural gas and oil sectors as important contributors; (ii) many independent experiments suggest that a small number of «super-emitters» could be responsible for a large fraction of leakage; (iii) recent regional atmospheric studies with very high emissions rates are unlikely to be representative of typical natural gas system leakage rates; and (iv) assessments using 100 - year impact indicators show system - wide leakage is unlikely to be large enough to negate climate benefits of coal - to - natural gas substitution.

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 data obtained included the first comprehensive measurements of aerosols and cloud particles throughout the atmospheric column during the evolution of multiple deep convective storm systems.

Ocean heat flux is a turbulent and complex system [7] which utilizes atmospheric measurement techniques such as eddy covariance to measure the rate of heat transfer expressed in the unit of joules or watts per second.

To test their hypothesis, the three scientists conducted a meta - analysis that included 1705 field measurements from 21 distinct sites from which they evaluated the effects of atmospheric CO2 enrichment on soil water content in both dryland and non-dryland systems.

Unmanned aerial system and tethered balloon system measurements have supplemented ARM Mobile Facility data to help improve understanding of atmospheric processes in the Arctic.

With the ever increasing divergence of surface temperatures (NASA GISS) from satellite ones (UAH / RSS), and the subsequent divergence of overheated climate models (IPCC CMIP5) to observed reality, it is worth some background on the atmospheric temperature measurement systems used to measure the temperature of the lower troposphere — the exact place where global warming theory is meant to occur and be measured:

Folks who do combustion, solar physics and atmospheric measurements understand that in such systems where the light source (s) are at the same temperature as the absorbers you can not naively use the absorption coefficient

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