In winter there are slight differences between wind roses in the troposphere and serious differences during the daytime in the stratosphere.
They transport heat and moisture as high as 21/2 miles into the troposphere, well above the atmospheric boundary layer.
ATTREX is studying moisture and chemical composition from altitudes of 55,000 feet to 65,000 feet in the tropical tropopause, which is the transition layer between the troposphere, or the lowest part of the atmosphere, and the stratosphere, which extends up to 11 miles above Earth's surface.
Chairman SUPARCO said " we undertake research studies in space and atmospheric sciences including satellite meteorology, satellite radiance, troposphere, stratosphere studies, atmospheric pollution, satellite geodesy and astronomy".
By bouncing a radio signal off the Earth's troposphere, rather than using a satellite transponder to transport the signal, this system overcomes significant terrain challenges that are extremely relevant in today's complex battlefield while avoiding the use of costly and scarce satellite resources.
His topics are radio waves and the troposphere, propagation, reflection and interference, refraction and path delay, absorption, rain attenuation, and attenuation by hydrometeors other than rain.
Nine white papers from the Aviation-Climate Change Research Initiative (ACCRI) report findings by meteorologists and other earth and environmental scientists on upper troposphere and lower stratosphere chemistry and transport, the climatic impact of contrails and contrail cirrus, contrail-specific microphysics, contrail/cirrus optics and radiation, metrics for comparing climate impacts from well mixed greenhouse gases and inhomogeneous forcing such as those from ozone and contrails, climate metrics and aviation, and research and development as keys to reducing emissions and their impact on health and climate.
Although climate cooling by sulphate aerosols also occurs in the troposphere, Crutzen says the great advantage of placing reflective particles in the stratosphere is their long residence time of about one to two years, compared to a week in the troposphere.
For many years, scientists believed that the troposphere (the lowest region of atmosphere where weather occurs) drove changes in the stratosphere (the layer directly above the troposphere) without any feedback.
According to most climate simulations, the enhanced greenhouse effect should have produced a sharper warming trend during the last several decades in the low troposphere the layer of air from just above the surface to about eight kilometers up than on the surface.
You shoot, you hit the troposphere, which is part of the atmosphere, it bounces down to a different station, and they catch it using the dishes on their shelters," said SPC Joseph Jackson, a tropospheric scatter radio operator.
