RoX (Reflectance bOX)
Rox is an automated field spectroscopy device capable of collecting unattended, continuous, long-term hyperspectral measurements.
It represents the evolution of prototypes such as Multiplexer Radiometer Irradiometer (MRI) , SFLUOR box  and SIF-System  developed from a collaboration between Jülich Research Center and the Remote Sensing of Environmental Dynamics Laboratory of the University Milano Bicocca. The basic routines of RoX are based on SPECY (Forschungszentrum Jülich, IBG-2: Plant Sciences).
RoX is designed for long term measurements of Solar radiance, reflected radiance and reflectance. Its robustness and flexibility make the RoX suitable for several application (e.g. vegetation monitoring, water quality, snow and ice properties).
The core of the system is the Flame spectrometer from Ocean Optics covering the Visible/Near Infrared region (300- 950 nm). Upward and downward channels of RoX allow to sequentially measure the solar irradiance and the reflected radiance from the canopy.
