1.4 GHz 辐射计 ELBARA 于 2001 年在伯尔尼大学应用物理研究所与 ETH 合作建造,用于土壤湿度研究,特别是根据表土含水量的动态来推断土壤水力特性。 ELBARA 与 MORA 一起使用,MORA 是一个较旧但等效的系统,频率为 11.4 GHz,并配有一组时域反射计 (TDR) 传感器。在正常设置中,辐射计在塔上以最低点和天顶之间的入射角进行操作。在此我们报告 ELBARA 的实现和功能。 2002 年首次测量的结果已在其他地方公布。
A 1.4 GHz radiometer, ELBARA, was constructed in 2001 at the Institute of Applied Physics, University of Bern, in collaboration with and for studies at ETH in soil-moisture research, especially to infer soil-hydraulic properties from the dynamics of the water content in the top soil. ELBARA is used together with MORA, an older, but equivalent system at 11.4 GHz and with a set of time-domain reflectometer (TDR) sensors. In the normal setup, the radiometers are operated from a tower at incidence angles between nadir and zenith. Here we report on the realization and on features of ELBARA. Results from first measurements in 2002 were presented elsewhere.
