  • New climatology on clouds and radiation from weather satellite data

    The properties and distribution of clouds around the globe are important to climate research. There is now a 28-year compilation of clouds and radiation – a cloud climatology – based on data from polar satellites. The Earth’s climate is largely determined by incoming solar radiation. Clouds help to reflect some of the radiation away. “Roughly 30 per cent of the ...

  • New figures on the impact of aviation on global climate change

    The contribution of aviation to climate change is increasing. A recent study uses radiative forcing (RF) to quantify and update values on the impact of aviation on the climate. It reveals an increase in total aviation RF of 14 per cent over the period 2000-2005. Radiative forcing (RF) is a measure of the imbalance between incoming solar radiation and outgoing infrared radiation at the surface of ...

  • Future SI standard for solar irradiance delivered to Switzerland

    Scientists from the National Physical Laboratory (NPL) have installed a Cryogenic Solar Absolute Radiometer (CSAR) at the Physikalisch-Meteorologisches Observatorium Davos World Radiation Center (PMOD/WRC) in Switzerland. CSAR is expected to replace the current standard for Direct Solar Radiation, significantly improving our knowledge and confidence for global climate research. Direct ...

  • What can we do about global warming?

    Science suggests that to mitigate the human contribution to global warming, we should reduce carbon dioxide and other greenhouse gas emissions. Because some additional warming is inevitable-even if we achieve significant greenhouse gas reductions quickly-we should make plans to adapt to coming climate change. If we are unable to control emissions and/or adapt to unavoidable changes quickly ...

  • Solar Power 2011 - Solar PV Breaks Records in 2010

    By J. Matthew Roney Solar photovoltaic (PV) companies manufactured a record 24,000 megawatts of PV cells worldwide in 2010, more than doubling their 2009 output. Annual PV production has grown nearly 100-fold since 2000, when just 277 megawatts of cells were made.  Newly installed PV also set a record in 2010, as 16,600 megawatts were installed in more than 100 countries.  This brought ...

  • NASA to Launch Global Warming Satellite After Loss

    Five years after a NASA satellite to track carbon dioxide plunged into the ocean after liftoff, the space agency is launching a carbon copy - this time on a different rocket. The $468 million mission is designed to study the main driver of climate change emitted from smokestacks and tailpipes. Some of the carbon dioxide is sucked up by trees and oceans, and the rest is lofted into the atmosphere, ...

  • Weather Stations Monitor Solar Panel Arrays

    Columbia Weather Systems has added two ISO second-class compliant solar radiation sensors as options for its Weather MicroServer to improve monitoring the efficiency of solar panel arrays. The Kipp and Zonen (top) and Hukseflux thermopile-based sensors can be mounted horizontally for global radiation measurement or at plane of array (POA) for PV solar applications. With high performance and ...

  • Chinese Energy Giant uses Delta-T’s SPN1 Pyranometer to monitor their New 100MW Solar Farm in Hebei Province.

    The China Three Gorges Corporation, one of the world’s largest renewable energy companies, is using the Delta-T Devices SPN1 Sunshine Pyranometer to monitor the performance of its huge new solar farm project in rural Quyang district - 230km southwest of Beijing. The solar farm is being built on more than 40 square kilometres of hilly, uncultivated land. The farm already has potential to ...

  • Lufft Compact weather sensor with Secondary Standard to revolutionize PV-Monitoring

    As of now the Compact weather sensor from Lufft WS510-UMB, equipped with a Kipp & Zonen pyranometer of the secondary standards, unites the precision of a variety of meteorological individual sensors in a single all-in-one device for the first time. The sensor is simply installed with only one cable, this means a measurable lower effort of installation and maintenance as well as significantly ...

  • As fast as lightning: The new weather sensor with lightning detection

    Up to now, there was little evidence to prove that damage or fires were caused by lightning. Lightning strikes can not only cause dangerous fires but can also give rise to great financial losses in the case of surge damage. This is especially critical for smart grids, solar panels and wind turbines, but also for building insurance, outdoor events and the forestry sector. “WS800”, the ...

  • New generation of Chinese environmental monitoring satellite now in orbit
