Abstract: Beschreibung: Hier sind die Ergebnisse der Auswertungen der hemisphärischen Bilder mit dem Programm HemiView Canopy Analysis Software (Version 2.1 SR1, Delta T Devices Ltd., www.delta-t.co.uk) angegeben. Weiterhin sind die Ergebnisse der Vermessungen an den Messpunkten angegeben. In der Übersicht sind die Mittelwerte (Zeile 6-14), die Standardabweichungen (Zeile 23-31) und die Variationskoeffizienten (Zeile 40-48) angegeben.

Additional info: Original data: FOR402 (Phase 2) ID: 50655-50663; Creators: Dalitz, Helmut and Oesker, Mathias (AG: B2-B2) This dataset has been migrated from the previous FOR402-Database to the FOR816-Database by the Central Data Management Z1/FOR816. Please keep in mind that the migration included all avilable metainfomation which were accessible through the FOR402-Database. Nevertheless, it can't be guaranteed that no thematic misinterpretation occured in the data/attribute description. There has been no further disciplin specfic control. In any case of ambiguity please contact the dataset creator.
