  • NREL updates solar radiation database

    The U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL) and collaborators released a 20-year updated version of the U.S. National Solar Radiation Database, a web-based technical report that provides critical information about solar and meteorological data for 1,454 locations in the U.S. and its territories. The updated database covers 1991-2010 and includes data ...

  • Climate models may be overestimating the cooling effect of wildfire aerosols

    Original story at MIT News Whether intentionally set to consume agricultural waste or naturally ignited in forests or peatlands, open-burning fires impact the global climate system in two ways which, to some extent, cancel each other out. On one hand, they generate a significant fraction of ...

  • New High-Accuracy Solar Radiation Sensor Integrated with Weather Station

    On a recent project for Swinerton Renewable Energy, Columbia Weather integrated the newly released Hukseflux SR20 solar sensor into a new weather monitoring system. SR20 is a pyranometer of the highest category in the ISO 9060 classification system: secondary standard. This solar radiation sensor is used where the highest measurement accuracy is required. The weather station utilizes an Acromag ...

  • New SR25 pyranometer takes solar radiation measurement to the next level

    When measuring solar radiation professionally, measurement accuracy and data availability are key. Data availability is reduced by dew and frost deposition on the domes of traditional pyranometers, whether these are ventilated or not. Hukseflux Thermal Sensors has developed an ISO 9060 secondary standard pyranometer with sapphire outer dome and internal heater that solves these ...

  • Italian Manufacturer Soluzione Solare presents a new solarimeter to measure solar radiation at the trade fair Intersolar Europe

    The Italian company Soluzione Solare has developed the new solarimeter Litemeter - a tool for measuring solar radiation and to determine whether a solar system is performing at correct levels. The new product is suited for photovoltaic systems that use small data loggers. It consists of a crystalline silicon solar cell and electronics, encapsulated in a UV resistant aluminium case. In contrast ...

  • Predicting the radiation risk to European Space Agency astronauts

    European scientists have developed the most accurate method yet for predicting the doses of radiation that astronauts will receive aboard the orbiting European laboratory module, Columbus, attached to the ISS this week.  The new software package accurately simulates the physics of radiation particles passing through spacecraft walls and human bodies. Such techniques will be essential to use for ...

  • Astronauts face radiation threat on long Mars trip

    Astronauts traveling to and from Mars would be bombarded with as much radiation as they'd get from a full-body CT scan about once a week for a year, researchers reported Thursday. That dose would, in some cases, exceed NASA's standards and is enough to raise an astronaut's cancer risk by 3 percent. As plans for deep space exploration ramp up, radiation is a big concern — from high-energy ...

  • LG Sonic introduces Depth, GPS and Solar Radiation sensors for better algae prediction

    LG Sonic introduces a water level sensor to measure the depth of water reservoirs, and a pyranometer to measure sun radiation. Furthermore, LG Sonic has decided to incorporate a GPS sensor in their algae control system, the MPC-Buoy, in order to determine the exact location of each system accurately. The sensors can be integrated into the ...

  • 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 ...

  • Solar cycle not to blame for warming

    European scientists have dug deep to dismiss once again the old argument that climate change might be a consequence of solar radiation rather than atmospheric chemistry. The world is warming, they confirm, because more greenhouse gases are getting into the atmosphere, and the changes in the solar cycle are not a significant ...

  • Solar PV inverter system

    The only fuel of a solar PV inverter system is the incident irradiance. Of course, there are many local factors that make it difficult to evaluate this local resource accurately without actually measuring it (which is obviously the best thing to do). All solar inverters involve a lot of simplifying assumptions. For example, shading is an important factor, but is usually incorrectly estimated, ...
