NIR reflectance BoX

The NoX automatic Field spectrometer is a new JB product. It allows measuring from Visibile up to the Near Infrared region (1650 nm). Its low power consumption and rugged case makes it suitable for installation in harsh enviroments: from the poles to the equator. From vegetation to snow the NoX is suitable for researches where the NIR range makes the difference.



The NIR reflectance box (NoX) is an unique instrument, enabling the continuous observation of Up-welling and Down-welling radiance in the visible near infrared region. It measures spectral data of high resolution (approximately 3 nm), yet is built to withstand the hazards of a permanent outdoor installation.

It represents the evolution of prototypes such as the 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 the FloX are based on SPECY (Forschungszentrum Jülich, IBG-2: Plant Sciences).

The NoX is specifically designed to measure Radiance and reflectance under natural light conditions. Therefore the design is optimized to achieve maximum efficiency in terms of: Signal to Noise Ratio, Spectral Resolution and quick acquisition time. Different combination of spectrometers can be selected by the users (e.g. SR4, FLAME, QEpro for the visible range. FLAME-NIR or NIRquest for the NIR range. All from Ocean Optics). Upward and downward channels of the NoX allow to measure the solar irradiance (making use of JB COS) and the reflected radiance from the canopy. In order to keep a stable level of dark current the spectrometers are embedded in a temperature controlled housing. The signal-to-noise is maximized thanks to accurate automatic optimization of the signal of both channels and a high performance optical light throughput.

How do I process the NoX data?

NoX is saving raw data. To convert it into radiance and compute reflectance and a variety of vegetation indices, an open source R package is available. A graphical user interface makes the data processing easy for any customer to allow processing of years of data with a few clicks.

How can the NoX be integrated for remote access and live datastream

The basic NoX is equipped with an USB interface to stream data directly to a connected computer. The NoX is also able to pass a sub selection of variables (VIs and vital data) via SDI-12. The optional embedded PC, if connected to internet (LAN, WLAN, mobile network) allow daily data stream of the full data set.
