Measuring Earth’s Temperature
2014-01-14 08:16:14

ESA Like thermometers in the sky, satellite instruments can measure the temperatures of Earth’s surfaces. ESA’s new GlobTemperature project is merging these data from a variety of spaceborne sensors to provide scientists with a one-stop shop for land, lake and ice temperature data. Information on land surface temperature is a key parameter for studying the Earth system. It plays an important role in physical processes such as atmospheric convection and surface evaporation,...

Lee Rannals for redOrbit.com - Your Universe Online There are satellites for nearly everything out in orbit now-a-days, including some that are meant just to provide measurements of the surface temperature of oceans and seas. These thermometers in the sky led to the meeting of scientists to review data from new satellite missions and scientific progress in the field. The European Space Agency said that measuring the sea-surface temperature (SST) across regional and global scales is...

ESA Under Press To Launch Sentinel Missions

The loss of the Envisat satellite is affecting services by Europe´s Global Monitoring for Environment and Security program. Efforts are being coordinated with other space agencies to fill some of the gaps, but the situation adds further urgency to launch the Sentinel missions. Carrying an array of sophisticated instruments, Envisat provided a continuous stream of information about the state of our planet for 10 years. Envisat not only advanced science, but also supplied data for...

ESA Declares End To Lost Envisat's Mission

After spending more than 10 years in space, orbiting the Earth more than 50,000 times, Envisat´s mission has ended, according to a report from ESA today. The satellite had been lost on April 8, 2012, and though teams had tried their best to re-establish contact with the eight-ton satellite, they have now declared its mission has ended. According to ESA, a team of engineers has spent the past month trying to regain control and communication with Envisat from a variety of ground...

ESA Still Trying To Communicate With Flagship Satellite
2012-04-13 11:16:28

Ground controllers from the European Space Agency (ESA) are still trying to make contact with the space agency's flagship Earth observation mission, Envisat. Radar pictures taken from the ground appear to show that the satellite is intact, but there is no confirmation that Envisat has entered the "safe mode" of an ailing spacecraft. During this mode, the spacecraft ensures the solar panel is pointed at the Sun and that onboard power systems are prioritized above all other activity....

ESA Loses Contact With Envisat
2012-04-12 09:03:59

Controllers from the European Space Agency (ESA) have lost communication with the space agency's flagship Earth observation mission known as Envisat. The mission controllers stopped receiving data from the spacecraft on Sunday, and have not been able to re-establish communications. Envisat, which launched in 2002, has been operating five years longer than its planned mission. While losing communications with satellites is not an uncommon problem, a recovery team is still working to...

ESA's Earth-observing satellites are helping to understand the intricate role that Eurasia's boreal forest "“ the planet's largest land ecosystem "“ plays in the chemical make-up of the atmosphere and the global climate system. By fostering new use of Earth observation data through the Atmosphere-Land Interaction Study (ALANIS), insight is being gained into how boreal forests contribute to greenhouse gas and aerosol concentration, and into the processes governing the interplay...

More wildfires have burned around the Russian capital this year than in the last decade and a half, according to sensors aboard ESA's observation satellites. The forest and peat bog fires ignited this summer amid an unprecedented heat wave of up to 40ºC. Working like thermometers in the sky, the Along Track Scanning Radiometer and the Advanced Along Track Scanning Radiometer on ESA's ERS-2 and Envisat satellites measure thermal-infrared radiation to take the...

Earth has a limited amount of water that recycles itself in what is called the "Ëœwater cycle'. Climate change, weather and human life are highly affected by changes in this continuous, interconnected cycle. Observing and monitoring the key variables governing the global water cycle is essential to our understanding of the Earth's climate, forecasting our weather, predicting floods and droughts, and improving water management for human use. Recent advances in Earth observation (EO)...

Aerosols, very small particles suspended in the air, play an important role in the global climate balance and in regulating climate change. They are one of the greatest sources of uncertainty in climate change models. ESA's GlobAerosol project has been making the most of European satellite capabilities to monitor them. Using data from the Along Track Scanning Radiometer-2 on the ERS-2 satellite, the Advanced Along Track Scanning Radiometer and the Medium Resolution Imaging Spectrometer on...


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
