Betula_ermanii.mspct {photobiologyPlants}

Spectral data for 'Betula ermanii' leaves

Description

A dataset containing for wavelengths at a 1 nm interval in the range 350 to 1000 nm, tabulated values for total reflectance and total transmittance, for the upper and lower epidermis of leaves of different ages from Erman's birch (Betula ermanii) trees growing in the forest in Japan.

The variables in each spectrum are as follows:

• w.length (nm)

• Rfr

• Tfr

Usage

Betula_ermanii.mspct

Format

object_mspct collection object with six object_spct member objects, each with 651 rows and 3 variables

Note

We thank H. M. Noda for allowing us to include these data in our package. We have included here only data for two leaves from one species (Betula ermanii) and for wavelengths shorter than 1000 nm, from the much larger original data set. The whole data set is publicly available and the data easy to read into R. The data included here where measured with a Li-Cor LI-1800 spectroradiometer equipped with a LI-1800-12 (Li-Cor) integrating sphere, and consequently are for total reflectance and total transmittance. Further details on methods are available through the JaLTER web site. If you use these data in a publication, please cite the original source as given under references and contact the original author. In addition cite this package.
