NERO line NDVI (discontinued)

2008-06-07 → 2016-09-15 Greenland Ecosystem Monitoring CC BY-SA 4.0

The NERO line is a permanent vegetation transect crossing all the dominating vegetation types found in the study area. The progression in the vegetation greenness (Normalized Difference Vegetation Index; NDVI) is followed on the NERO line one to two times per month throughout the snowfree season. NDVI is measured by a Crop Circle Handheld System and scans are conducted by moving the sensor steadily forward (ca. 1 meter per second) approximately 75 cm above the vegetation. This results in a measuring footprint of approximately 10 x 45 m. For further details, please refer to the newest BioBasis manual available at the website.
