WISER I Spectroradiometer:

WISER (Wide Field Imager for Solar-Induced Fluorescence and Reflectance) I Spectroradiometer is an instrument used for measuring the fluorescence and reflectance of vegetation. It can be used for a variety of applications, including remote sensing of vegetation and crop stress, monitoring of photosynthesis and water use efficiency, and mapping vegetation biochemistry and productivity.

The WISER I Spectroradiometer is designed to measure solar-induced fluorescence and reflectance in the red and near-infrared (NIR) regions of the electromagnetic spectrum. Fluorescence, which is the re-emission of light by a substance after it has absorbed light, can provide information about the health and productivity of vegetation. Reflectance, on the other hand, measures the amount of light that is reflected by a surface and can provide information about the surface properties and biochemistry of vegetation.

The instrument is mounted on a tripod and can be easily moved to different locations. It consists of a spectroradiometer, a light source, and a field of view (FOV) selector. The spectroradiometer measures the fluorescence and reflectance of vegetation in the red and NIR regions of the spectrum, while the light source provides the light that is used to excite the fluorescence. The FOV selector can be used to select the area of the vegetation that is being measured, which allows for highly targeted measurements.

The WISER I Spectroradiometer can be used in a variety of different environments, including agricultural fields, forests, and wetlands. It is particularly useful for studying vegetation in remote and hard-to-reach areas, and can be used for both short-term and long-term monitoring.

The data collected by the WISER I Spectroradiometer can be used to create maps of vegetation health and productivity, which can be used by farmers and land managers to optimize crop yields and reduce the use of water and other resources. Additionally, the data can be used to study the impact of climate change on vegetation and to develop new strategies for managing and conserving natural resources.

In summary, WISER I Spectroradiometer is an advanced remote-sensing instrument designed for measuring fluorescence and reflectance of vegetation, this data will be useful in agriculture, forestry and wetland management, and the study of vegetation response to environmental changes.

The WISER I Spectroradiometer configuration, combining the MS-711, measuring the spectral range from 300 nm to 1100 nm (UV-Visible-NIR), and the MS-712, measuring the near-infrared (NIR) range between 900 nm and 1700 nm, designed to provide the most accurate outdoor solar spectral data.

With temperature-controlled sensor units and NIST traceable calibration, the WISER I delivers improved stability and long-term reliability is suitable for all weather conditions, and has an operational temperature range of -10 to 50 °C.

Often installed in fixed locations for meteorological, plant science, photovoltaic research, and material analysis applications, the WISER I is also suitable for use as a traveling reference, with separate power supplies for both sensors, a calibration uncertainty budget, and software, including “Nami,” for sensor management, data analysis, and visualization.
