The Chilbolton rain radar is a world leader in dual-linear-polarisation measurement techniques. The radar is mounted on a 25m antenna, which gives the radar a high spatial resolution of 0. 25°. Its operating frequency of 3 GHz ensures that the signal is attenuated as little as possible. Researchers are able to predict propagation effects up to at least 40 GHz using the radar, since it can characterise the distribution of rain drop sizes using differential reflectivity.  2, record 10, English, - rain%20radar

Forest biometrician.... Participate in a team oriented research project assessing the carbon dynamics of forest ecosystems at country to regional scales, including the effects of changes in land cover, land use, and land management. The current research focus is to quantify the carbon flux(either sink or source) from changes in land use and land cover for several major boreal, temperate, and tropical countries. The primary duties will be : 1) estimate errors and their propagation for all components of national-scale terrestrial C budgets; 2) design sampling strategies for data collection from field sites to remote sensing scenes; 3) perform statistical analysis of inventory data for estimating status and trend of forest biomass-carbon densities; 4) design a data management system, including quality control procedures, for keeping track of estimates of means and associated errors of carbon budget components that vary over time and space....  2, record 12, English, - forest%20biometrician
