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 ...

Glacier-melting debate highlights importance of satellites
The intense public debate on how rapidly the Himalayan glaciers are retreating highlights the necessity for the constant monitoring of glaciers worldwide by satellites. Since glaciers are among the most reliable indicators of climate change and because they can have a major influence on water availability, knowledge of the recent changes and future behaviour is of great interest for climate ...

Climate studies to benefit from 12 years of satellite aerosol data
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, ...

Improved climate forecasting as TRUTHS moves closer to launch
The National Physical Laboratory (NPL), in partnership with Airbus Defence and Space, is expecting to shortly complete negotiations with the UK Space Agency (UKSA) for the award of the final contribution to funding in excess of £1.25M. This funding will move the proposed TRUTHS missiona step closer to launch, and with it the prospect of the data needed to reduce uncertainty in climate ...

NASA`s NPP Satellite Completes Comprehensive Testing
The NASA National Polar-orbiting Operational Environmental Satellite System (NPOESS) Preparatory Project (NPP) has successfully completed its most comprehensive end-to-end compatibility test of the actual satellite and all five scientific instruments at Ball Aerospace & Technologies Corp's production and test facility in Boulder, Colo. During the four-week NPP Compatibility Test 4 (NCT4), ...

NASA Transfers Operational Control Of Environmental Satellite
The Suomi National Polar-orbiting Partnership (NPP) satellite, a partnership between NASA and the National Oceanic and Atmospheric Administration (NOAA), was transitioned to NOAA operational organization control Feb. 22. The transition marks the next step of the mission that supports NASA's Earth science research and NOAA's weather forecasting missions. Suomi NPP continues the observations of ...

Mapping Earth`s soil moisture with NASA
Professor Dara Entekhabi from the Massachusetts Institute of Technology is to lead a science team designing a NASA satellite mission to collect global soil moisture measurements and other data seen as key to improving weather, flood and drought forecasts and predictions of agricultural productivity and climate change. At present, scientists have no network for gathering soil moisture data as they ...

Sentinel 6 Goes Live,a welcome addition to Aratos Earth Observation Data Platform
The Sentinel-6 which was launched back in 11/22/2020 has just finished calibration and is now operational. Sentinel-6 is equipped with a Synthetic-aperture radar (SAR) altimeter and an Advanced Microwave Radiometer for Climate (AMR-C). This enables Sentinel-6 to acquire measurements with better accuracy and less noise with respect to Jason-3 satellite regarding maritime. ...

Clouds’ climate impact defies simple analysis
Scientists have just been presented with new evidence on how tropical clouds’ climate impact affects rates of global warming, and therefore need to be factored into computer simulations of climate change over the next century. Confusingly, one study says thin tropical clouds at 5km height are far more common than thought, and have a substantial cooling effect on climate. The other ...

Satellite Takes 3-Billionth `Photo` Marking 5th Year in Space
For a satellite that's only five years old, CALIPSO has accomplished a lot. The Earth-observing spacecraft took its three-billionth photo - actually a "lidar profile" - on June 2. June 7 marked the fifth year in space for the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation satellite. For images go to http://www.nasa.gov/mission_pages/calipso/mission/5years.html# Since its ...
