  • 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 ...

  • 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 ...

  • NASA launches airborne study of Arctic atmosphere, air pollution

    The recent decline of Arctic sea ice is one indication that this region is undergoing significant environmental changes related to climate warming. To investigate the atmosphere's role in this climate-sensitive region, NASA and its partners have begun the most extensive field campaign ever to study the chemistry of the Arctic's lower atmosphere. The Arctic Research of the Composition of the ...

  • Explained: radiative forcing

    This is the first of a two-part “Explained” on the scientific concepts underlying the concept of the greenhouse effect and global climate change. When people talk about global warming or the greenhouse effect, the main underlying scientific concept that describes the process is radiative forcing. And despite all the recent controversy over leaked emails and charges of poorly sourced references ...

  • 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 ...

  • 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 ...

  • East Asian air pollution to have bigger global impact under climate change

    Greater amounts of air pollutants emitted in East Asia will move around the globe under climate change, a recent study predicts. Changes to wind speeds and air pressure will mean that movement of pollution from this region is enhanced under a changing climate. These results highlight the need for globally coordinated efforts to tackle air pollution and climate change. Long-range transport of air ...

  • Are sunspots prime suspects in global warming?

    (AXcess News) - It's a modern-day climate scuffle William Herschel would recognize. He should. He helped trigger it. In 1801, the eminent British astron­­omer reported that when sunspots dotted the sun's surface, grain prices fell. When sunspots waned, prices rose. He suggested that shifts in grain prices were a stand-in for shifts in climate. Large numbers of sunspots led to a ...

  • Ball Aerospace Wins Contract to Build Air Quality Sensor for KARI

    Ball Aerospace & Technologies Corp. has been awarded a contract from the Korea Aerospace Research Institute (KARI) to build the Geostationary Environment Monitoring Spectrometer (GEMS) for the National Institute of Environmental Research in the Ministry of Environment of South Korea.  GEMS is a geostationary scanning ultraviolet-visible spectrometer designed to monitor trans-boundary ...

  • Ball Aerospace Selected by NASA for TEMPO Air Pollution Mission

    Ball Aerospace & Technologies Corp. is part of a team selected to build the first space-based instrument to monitor major air pollutants across the North American continent for NASA's Tropospheric Emissions: Monitoring of Pollution (TEMPO) mission. Led by the Smithsonian Astrophysical Observatory, Cambridge, Mass., the TEMPO team will build a geostationary ultraviolet-visible (UV-VIS) ...
