"The general objective of this project is to analyze the relationship between biosphere-atmosphere CO2 exchange and phenological canopy status or greenness of the International Phenological Garden in Doksany observatory (50\u00B027\u201930%22 N, 14\u00B010\u201913%22 E, 158 a.s.l). Canopy greenness is quantified using two different approaches: from digital webcam images, using indices derived from red, green and blue (RGB) color channel brightness and with satellite remote sensing (e.g. NDVI). The project is based on a field micrometeorological measurements, phenological observations, CO2 exchange measurements. Prominent part of the project is homogenization and improvement of the existing algorithms for processing digital imagery."@en .

"We tested the relationships between the Growing season index (GSI) and vegetation indices computed from continuous spectroradiometric measurements and between the iGSIo and C02 fluxes observed with the eddy covariance technique. A strong relationship was found between the iGSlo and (i) the Normalised Difference Vegetation Index (NDVI) and (ii) the net ecosystem carbon exchange (NEE)."@en . . . "17"^^ . . "17"^^ . .
