Polarization is the phenomenon in which waves of electromagnetic radiation are restricted in direction of vibration. The reason polarization state is worth contemplating is that two beams of radiation, otherwise identical, may interact differently with matter if their polarization states are different. Thus, observing the polarization of scattered light in the atmosphere provides a unique way to probe clouds, precipitation and aerosol. In this project, you will have the opportunity to explore the use of dual-polarisation radar to make novel observations of the atmosphere. To accomplish this you will utilize observations from the recently upgraded UK weather radar network to investigate the wealth of unexplored information provided by polarimetric variables observed with dual-polarization radar. You will use these new observational capabilities to improve our understanding of making precipitation observations and explore how these experimental techniques may be incorporated into improving operational observational systems and forecasts.

极化是电磁辐射波的振动方向受到限制的现象。偏振态值得考虑的原因是，两束辐射（在其他方面相同）如果偏振态不同，则可能与物质产生不同的相互作用。因此，观察大气中散射光的偏振提供了一种探测云、降水和气溶胶的独特方法。在这个项目中，您将有机会探索使用双偏振雷达对大气进行新颖的观测。为了实现这一目标，您将利用最近升级的英国天气雷达网络的观测结果来调查通过双偏振雷达观测到的偏振变量所提供的大量未探索的信息。您将使用这些新的观测功能来提高我们对降水观测的理解，并探索如何将这些实验技术纳入改进业务观测系统和预报。
