The CoSMOS (Campaign for validating the Operation of the Soil Moisture and Ocean Salinity mission) campaign was conducted during November of 2005 in the Goulburn River Catchment, in SE Australia. The main objective of CoSMOS was to obtain a series of L-band measurements from the air in order to validate the L-band emission model that will be used by the(More)
Recent studies of passive L-band observations over forests have shown that the average canopy transmissivity in temperate coniferous and deciduous forests is on the order of 0.4–0.5. Although the canopy would therefore be expected to transmit a reasonable amount of ground emission, the total emission observed above the canopy shows very little variation(More)
In this paper, the L-band Microwave Emission of the Biosphere (L-MEB) model used in the Soil Moisture and Ocean Salinity (SMOS) Level 2 Soil Moisture algorithm is calibrated using L-band (1.4 GHz) microwave measurements over a coniferous (Pine) and a deciduous (mixed/Beech) forest. This resulted in working values of the main canopy parameters optical depth(More)
ESA’s Soil Moisture and Ocean Salinity (SMOS) mission has been designed to extend our knowledge of the Earth’s water cycle. Soil Moisture and Ocean Salinity records brightness temperatures at the L-band, which over land are sensitive to soil and vegetation parameters. On the basis of these measurements, soil moisture and vegetation opacity data sets have(More)
SMOS (Soil Moisture and Ocean Salinity), is the second mission of “Earth Explorer” to be developed within the program “Living Planet” of the European Space Agency (ESA). This satellite, containing the very first 1.4GHz interferometric radiometer 2D, will carry out the first cartography on a planetary scale of the moisture of the grounds and the salinity of(More)
In 1981 a child's life was worth less than $100. The sum of $100, wisely spent on each of the poorest 500 million mothers and young children in the world, could have brought improved diets and easier pregnancies, elementary education and basic health care, safer sanitation, and more water. In practice $100 proved too high a price for the world community(More)
