Sentences with phrase «measure atmospheric aerosol»

Using different instruments, satellites can measure atmospheric aerosol levels, ground elevations, and more.

Not exact matches

After allowing for humidity and rainfall, they found that «aerosol optical thickness» — a measure of the concentration of atmospheric particles — decreased by only 10 to 15 per cent compared with the same periods in 2002 to 2007 (Geophysical Research Letters, in press).

And by carefully measuring and modeling the resulting changes in atmospheric composition, scientists could improve their estimate of how sensitive Earth's climate is to CO2, said lead author Joyce Penner, a professor of atmospheric science at the University of Michigan whose work focuses on improving global climate models and their ability to model the interplay between clouds and aerosol particles.

India, another huge source of atmospheric pollution, recently allowed European scientists to measure its high - level aerosols, an experiment that also includes flights into Nepal and Bangladesh.

The measured energy imbalance accounts for all natural and human - made climate forcings, including changes of atmospheric aerosols and Earth's surface albedo.

Aerosols, with their short atmospheric lifetime, and highly variable geographic distribution, are difficult to observe quantitatively from space with currently available satellite instrumentation which only measure the spectral intensity of reflected solar radiation.

On the other hand I am co-plotting, down to sub-annual timescales up to 3 or even perhaps 4 well defined physical parameters relating to both the sea surface (e.g. SST, chlorophyll a, surface leaving radiance), the immediate subsurface (e.g. diffuse attenuation of 490 nm light to approx 50 m depth) and atmospheric aerosol size e.g. AOT at 865 and 890 nm — all measured with modern, state of the art surface telemetry and remote sensing methods and simply looking for mechanistic links between these parameters on sub-annual timescales.

The measured energy imbalance accounts for all natural and human - made climate forcings, including changes of atmospheric aerosols and Earth's surface albedo.

Perhaps, more relevant: an astronomer noted that during the period since 1995 when the brightness of the Full Moon is measured (he claims a good indicator of atmospheric volcanic aerosols) it has been at the highest levels since the 60s.
