Multi-Spectral data

Sensor box with 12 multi-spectral sensors (two upper rows) and 6 thermal infrared sensors (bottom row)

The multi-spectral measurements are made using an array of 15° FOV Skye 4-channel sensors, each with 0-5 V signal output. When installed, these sensors are configured in a similar way to the Everest thermal infrared radiometers (bottom row in first picture), such that the six downward-looking sensors have the same incidence angle and footprints as the six PLMR beams. However, to correct for incident radiation, an upward-looking sensor with cosine diffuser is also installed. Each sensor weighs approximately 400g and has a size of 8.2cm × 4.4cm without the cosine diffuser or field of view collar attached). Two arrays of 4 channel sensors are installed, with the following (matched) spectral bands:

Sensor VIS/NIR (SKR 1850A)
Channel 1 MODIS Band 1 620 - 670nm
Channel 2 MODIS Band 2 841 - 876nm
Channel 3 MODIS Band 3 459 - 479nm
Channel 4 MODIS Band 4 545 - 565nm

Sensor SWIR (SKR 1870A)
Channel 1 MODIS Band 6 1628 - 1652nm
Channel 2   2026 - 2036nm
Channel 3 MODIS Band 7 2105 - 2155nm
Channel 4   2206 - 2216nm

NDVI observation

Here is an example showing the NDVI distribution over focus farm 09, flight patch 05. All collected data can be downloaded via the Download Centre.
