Spectral Analysis of Plant Stress

Overview:

The Remote Sensing and Spatial Ecology (RSSE) research lab has acess to several field spectroradiometers, in addition to the aerial hyerpsectral system on HAMCAM.

As part of our suite of field instruments we have a GER-1500 specroradiometer.

Main Specs: 350 nm - 1050 nm in 512 channels

As shown (left) these are light, rugged, and field portable. The company has excellent customer care. They worked with us to produce a remote trigger and a tripod mount for both the instrument and spectralon panel.

As part of out laboratory instruments, the research lab also has an ASD Field Spec Pro. This instrument (350-2500 nm) is frequently used as part of darkroom and greenhouse experiments. In addition to these instruments, our research lab also has a lightweight (lower spectral range) ASD for use baloon measurements in the SWAMI system; and has acess to a further ASD Field Spec Pro (owned by the neighboring Rocky Mountain Research Station) and a GER-2600 (owned by the Geography Department). The RSSE research lab as part of a upgrade process is also purchasing a dual view spectroradiometer and an integrating sphere to enable in-house calibration.

The Assessment of Plant Stress is a topic of ongoing research by graduate students Jan Eitel and Meghan Calhoon. Jan's prior research has included the assessment of how disease (Rust) and water stress effects the spectral properties of Populus, while Meghan's reseaerch is focusing on evlauting the spectral properties of ponderosa pine under stress caused by fire. Jan as part of his PhD is now investigtaing the influence of stress and nutrients on wheat spectral properties.
