Methods: To study bond formation between ions and reactive surfaces, researchers previously had to expose surfaces to a beam of mass selected ions, then take the substrate outside the vacuum system and perform the analysis.

Brandon et al. (2013) assessed the reliability of a novel analysis system for Olympic weightlifting, comprising surface electromyography (EMG) equipment (to measure EMG amplitude within a muscle), synchronised with electrogoniometry (to measure joint angles), and a barbell position transducer (to measure the height of the barbell and thereby its displacement and linear velocity).

the 1.5 to 2 m observations of minimum temperatures that are used as part of the analysis to assess climate system heat changes (e.g., such as used to construct Figure SPM - 3 of Intergovernmental Panel on Climate Change [2007] and of Parker [2004, 2006] study) lead to a greater long term temperature trend than would be found if higher heights within the surface boundary layer were used.

The agency reached a stark conclusion after a recent geographical information system analysis: «No additional leasing involving surface disturbance can occur without significantly altering the ecological integrity and wild character of our state forest system.»

«The assessment is supported additionally by a complementary analysis in which the parameters of an Earth System Model of Intermediate Complexity (EMIC) were constrained using observations of near - surface temperature and ocean heat content, as well as prior information on the magnitudes of forcings, and which concluded that GHGs have caused 0.6 °C to 1.1 °C (5 to 95 % uncertainty) warming since the mid-20th century (Huber and Knutti, 2011); an analysis by Wigley and Santer (2013), who used an energy balance model and RF and climate sensitivity estimates from AR4, and they concluded that there was about a 93 % chance that GHGs caused a warming greater than observed over the 1950 — 2005 period; and earlier detection and attribution studies assessed in the AR4 (Hegerl et al., 2007b).»

If you limit the analysis to the energy balance (or temperature) at the surface then you miss the ocean's heat capacity, which happens to be the largest system component.

Considering Earth's average surface temperature as a reasonable metric (something more along the lines of total surface heat content is probably better, but average T is not a bad proxy for that), the standard systems theory analysis from the physical constraints implies that that average T is determined and constrained through a feedback process.
