Not exact matches

Half the group remained at Base Camp while the other half climbed the mountain to a maximum of 8,848 m. Measurements were taken in each group at week six and week eight of the trek.
Now, thanks to near - infrared spectral measurements taken by NASA's Cassini orbiter and analysis of near - infrared color signatures by researchers at the University of Wisconsin - Madison, Saturn's superstorm is helping scientists flesh out a picture of the composition of the planet's atmosphere at depths typically obscured by a thick high - altitude haze.
It is capable of measurements to altitudes approaching 30,000 feet over ranges of 1500 nautical miles, and can be operated at speeds that enable both relatively slow sampling and rapid deployment to field sites throughout the world.
Based on magnetic field measurements taken by the Messenger at an altitude as low as 9 miles, scientists have now discovered that Mercury, located just 36 million miles from the sun, possesses a magnetic field dating back almost four billion years.
«We have flown radiation sensors onboard 264 research flights at altitudes as high as 17.3 km (56,700 ft) from 2013 to 2017,» says Kent Tobiska, lead author of the paper and PI of the NASA - supported program Automated Radiation Measurements for Aerospace Safety (ARMAS).
Large scale dust storms change the atmospheric opacity and convection; as always when comparing mean temperatures, the altitude at which the measurement is made matters, but to the extent it is sensible to speak of a mean temperature for Mars, the evidence is for significant cooling from the 1970's, when Viking made measurements, compared to current temperatures.
They tell you how high up that is — but how many people actually looked and thought about the altitude at which the measurement is being done?
For orographic cumulus clouds, the G - 1 measurements will characterize in - cloud dynamics, microphysics, and aerosols, as well as the environmental variability around the clouds focusing on conditions upstream and downstream of clouds at multiple altitudes in the vicinity of the AMF1 site.
At an altitude of about 125 kilometers above the surface, measurements by the Venus Express probe have shown, the temperature drops to an amazingly low -175 °C, cool enough in theory for carbon dioxide ice or snow to form.»
Data from in situ measurements made at high - altitude stations in the HKH region, observations from satellitebased instruments, and global climate modeling study results are discussed.
These methane measurements come from Hiaper Pole - to - Pole Observations, which uses aircraft loaded with scientific instruments flying long distances at varying altitudes.
On average, the ozone measurement bias achieved by NDACC lidars is around 5 - 10 % below 20 km for instruments without Raman channels and 5 % for instruments with Raman channels, around 2 % at altitudes within 20 - 35 km, and around 5 - 10 % at altitudes above 40 km [Keckhut et al., 2004].
Plus, they are inherently a much less direct measurement of temperature: they actually measure microwave brightness, which must be mathematically processed to arrive at temperatures at various altitudes in the atmosphere.
Note that ppm and delta13C are not the same at all altitudes and evolve progressively, as illustrated by the airborne measurements of Nakazawa et al., Time and space variations of the carbon isotopic ratio, Tellus, 1993.
Both of the Nature Climate Change studies used a combination of direct measurements of temperature at various depths, a measurement of the altitude of the top of the ocean (sea level) from highly accurate satellite instruments, and measures of the mass of the water in the ocean, from the GRAIL gravity research project.
The crowd of government - financed alarmists artificially introduced this signal by excluding Canadian, Siberian, high - altitude and other «inconvenient» measurements from data sets, by various «adjustments» fitting the desired outcome, by placing meteorological stations on airport tarmacs, at air conditioners» exhausts and in other artificially heated places, and by blatantly omitting, negating, and even reversing (as in prof. Mann's case) actual results.

Another avenue for monitoring is satellite measurements of column inventories of the gases, which provide much more detailed spatial coverage but no vertical resolution, in which air masses at different altitudes may carry gases that originated from different parts of the Earth's surface.
Satellite temperature measurements are inferences of the temperature of the atmosphere at various altitudes as well as sea and land surface temperatures obtained from radiometric measurements by satellites.
The high level of interest in scientific circles in upper tropospheric (and stratospheric) water vapor is because it is easy to demonstrate by theory and measurement that small amounts of water vapor at high altitudes have disproportionate effects.
