In late March, the Obama administration released guidance directing U.S. EPA to address methane emissions from the oil and gas industry, after a number of studies measuring emissions from the air, known as «top - down» measurements, showed that the agency's emissions estimates for the industry were too low (ClimateWire, March 31).

In previous work, air measurements from planes and a sparse network of monitoring towers have revealed that the inventory - based numbers are coming in low — roughly 50 percent low.

The activists cite a letter from Berns stating that «mice are available» with a low background incidence of tumours, and a high sensitivity to carcinogens, «thereby reducing both the time of testing and the number of animals required for a reliable measurement».

While this number is higher than the previous estimate made in the late 1990s based on ground measurements, the new research includes data on more volcanoes, including some that scientists have never visited, and it is still lower than human emissions of sulfur dioxide pollution levels.

The ligand shell has a low symmetry and produces a large number of signals in conventional proton - NMR measurement (see image, left).

For many years measurements of the number of neutrinos produced in the Sun were much lower than theories predicted, a problem which was recently resolved through a better understanding of the effects of neutrino oscillation.

When the researchers compared those numbers, they found that ambulatory blood pressure — an average of all measurements taking while they were awake — tended to be higher than their in - office averages, not lower.

Remember, the scale number may not budge, or it may go up, but the way you FEEL combined with results of other measurements can reinforce that you are succeeding in so many ways — you might be gaining muscle mass, losing fat, losing inches, fitting into your clothes better, feeling more energized, sleeping better, improving your sex life, lowering your cholesterol, bettering your overall health, etc. — the list goes on and on.

«A number of studies have suggested that long - term irradiance - based measurements of cloud cover from satellite may be unreliable due to the inclusion of artifacts, difficulties in observing low - cloud, biases connected to view angles, and calibration issues [1, 2, 3, 4].

When the number of measurements is low for a large area that may plausibly behave differently from the rest, that makes the estimate of the overall average less accurate.

Origin representatives said that wind measurements were too low and that «the wind farm did not meet the company's requirements on a number of fronts».

Temperatures aloft can be measured in a number of ways, two of which are useful for climate monitoring: by radiosondes (balloon - borne instrument packages, including thermometers, released daily or twice daily at a network of observing stations throughout the world), and by satellite measurements of microwave radiation emitted by oxygen gas in the lower to mid-troposphere, taken with an instrument known as the Microwave Sounding Unit (MSU).5 The balloon measurements are taken at the same Greenwich mean times each day, whereas the times of day of the satellite measurements for a given location drift slowly with changes in the satellite orbits.

TSI is directly correlated with sunspot numbers, and the long and deep solar minimum we just came through where the sun was blank for long periods of time would necessarily mean that TSI was also lower for an extended period of time This is not what the measurements show.

Variation from the mean is the wrong measurement for exactly the «dice» reason you gave, and using «number of record highs versus lows» is likewise the wrong approach for the same reason.
