Field sites exposed to higher volumes
of air traffic contained higher levels of sediment heavy metals,
supporting the hypothesis that aerial deposition of heavy metals is
occurring in areas near some airports.

We have weather guys, pilots; however none so far that can go up againt my science back ground and I have a lot of it.
President Obama is full of surprises. But even expectant reporters were taken aback when White House science adviser John Holdren used his first interview on April 18, 2009 to announce, “Global warming is so dire, the Obama administration is discussing radical technologies to cool Earth's air.”
With the first feedback effects from methane releases starting to kick in and our space colony's atmospheric CO2 levels surging toward the “Do Not Exceed” redline of 440 parts per million, Holdren declared that the Obama administration is considering “last resort” technologies to chill the global greenhouse village - aka the 'hood
Referring to “radical” technologies that include spreading a sunlight-reflecting artificial cloud cover, Holdren declared, “It's got to be looked at. We don't have the luxury of taking any approach off the table.”
I understand how contrails form. I understand why they form at some altitudes and not others. I understand why they are more common in some places than others. I understand why they sometimes last longer than at other times. I understand how they can cause the formation of cirrus clouds.
The government isn't telling me they aren't "spraying".
There are more efficient ways to depopulate and understanding of the climate is so limited that the idea we can control it is frankly, absurd.
Leosphere has recently announced the deployment of its 50th Lidar station. Cloud, aerosol Lidars and Wind Lidars are now installed in 14 countries contributing to regional and global monitoring of meteorological and climate change processes. Still considered an emerging technology just a few years ago, the wind Lidar and the aerosol Lidar are now widely used as routine observation instruments feeding meteorological databases and models. While cloud and aerosol Lidar networks keep sprouting in various regions of the world, high resolution wind Lidar profiler was still missing in meteo stations. Our new WLS 70 might well light up the sky to answer that need...
As part of the Earth Observation Programmes, the European Space Agency has been involved in the definition, studies and developments for various types of lidar sensors. At first, a Doppler Wind Lidar, for 3-D tropospheric wind profiling, is due to fly on board the forthcoming Atmospheric Dynamic Mission (ADM), also called Aeolus; next, a Backascattering Lidar, ATLID, for Cloud and Aerosols observations, is proposed to be flown as a joint European-Japanese mission. Last, the Differential absorption lidar (DIAL) is being considered for high resolution/accuracy water vapour atmospheric profiling. The paper will give an overview of related technology developments and applications.
