Description
  • Na základě zpracování naměřených dat definovat pomocí nově vytvořeného modelu vztah mezi fenologickými fázemi, počasím a dynamikou CO2 mezi biosférou a atmosférou na Mezinárodní fenologické zahrádce v Doksanech.
  • 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°27’30%22 N, 14°10’13%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)

  • Testovali jsme vztahy mezi Growing season indexem (GSI) a vegetačními indexy ze spektroradiometrických měření a mezi GSI a toky C02 z eddy-kovariančních měření. Silný vztah byl nalezen mezi GSI a normalizovaným diferenčním vegetačním indexem (NDVI) a GSI a čistou ekosystémovou výměnou uhlíku{NEE). (cs)
  • 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)
