220 GHz卷云非球形冰晶粒子雷达反射率因子与冰水含量关系研究
Relationship between radar reflectivity factor and ice water content of non-spherical cirrus ice crystals at 220 GHz
摘要
Abstract
For the practical needs in the data processing of terahertz radar,the discrete dipole approximation meth?od is used to calculate the backscattering cross-section of non-spherical ice crystals with different shapes. Based on the latest refined ice cloud model,the relationship between the radar reflectivity factor Zm and ice water content I in 220 GHz is established. The calculation results show that both the shapes of the non-spherical ice crystals and the ice cloud model have a particular influence on the Zm-I relationship. This study has application value for cloud parameter inversion of mid-latitude cirrus clouds,and it can be helpful for the development of terahertz radar in the detection of clouds.关键词
