  • Space watch on air quality

    Sensitive sensors located in space are being drafted to help scientists monitor the state of the quality of the Earth’s air. With air pollution becoming one of the world's biggest dangers to society's health and an economic drain on some nations, current and up- to-date information on air pollution levels and their movement are vital to researchers tackling this problem. The ESA Earth Observation ...

  • Himalayan pollution `could impact monsoon cycle`

    Researchers have shown that pollution from China, India, Nepal and Pakistan can reach altitudes of over 5,000 metres in the Himalayas, contributing to the warming of the atmosphere and potentially affecting the South-East Asian monsoon cycle. They also found that new aerosol particles — ultrafine particles suspended in the atmosphere — can form at these heights. The ...

  • Atmospheric aerosol climate caution

    Carbon dioxide is not the only problem we must address if we are to understand and solve the problem of climate change. According to research published this month in the International Journal of Global Warming, we as yet do not understand adequately the role played by aerosols, clouds and their interaction and must take related processes into account before considering any large-scale ...

  • New Space Sensor As A Hosted Payload To Track Air Pollution Across North America

    NASA has selected a proposal from the Smithsonian Astrophysical Observatory in Cambridge, Mass., to build the first space-based instrument to monitor major air pollutants across the North American continent hourly during daytime. The instrument, to be completed in 2017 at a cost of not more than $90 million, will share a ride on a commercial satellite as a hosted payload to an orbit about ...
