The amount of sunlight being absorbed or reflected by Earth is one of the driving forces for weather and climate. Satellites are providing this information with unprecedented accuracy.
Thirty-five years ago this week, NASA's Jet Propulsion Laboratory launched an experimental satellite called Seasat, with the mission to study Earth and its seas. An unexpected malfunction ended the mission after just 106 days, leading some to look on the satellite as a failure.
A campaign in one of the remotest regions on Earth in ensuring that the SMOS mission is delivering reliable data.

Researchers at the Institute of Electronics, Communications and Information Technology (ECIT) and the Northern Ireland Semiconductor Research Centre (NISRC) at Queen's University Belfast have devised a way to eliminate the need for motors in space borne radiometers by incorporating liquid crystals in their Frequency Selective Surface (FSS) antenna arrays.
Radiometrics Corporation announces successful deployments of the MP-3000A radiometer system for improved prediction of short-term weather impacting wind power generation and utility load forecasting.
The bolometer, invented in 1878 by Samuel Pierpont Langley, measures the energy of incident electromagnetic radiation. It consists of an absorptive element connected to a heat sink through a thermal link. The absortive element raises its temperature above that of the heat sink when radiation impinges on it. The higher the energy the higher the temperature rises. Old bolometers used metals while newer ones used semiconductors and superconductors as the absorptive elements. Bolometers can...
