Obtaining & Unpacking

The reflectance spectra of the needles of young (less than 40 years old) individual Scots pine and Norway spruce and the leaves of a birch. The data were collected in Finland and Sweden. Spectroradiometric measurements were made in clear weather during the growing season in June 1992. Each measurement represents the average spectrum of thousands of leaves of a growing tree.

Measuring equipment: PR 713/702 AM spectroradiometer.

Wavelength interval: 390 nm - 850 nm.

Wavelength resolution: 5 nm.

File formats: The available formats are ASCII and MATLAB.

Measurer: Ph.D. Raimo Silvennoinen, Vaisala Laboratory, University of Joensuu, Finland.
