materials.mspct {photobiologyFilters}

Spectral reflectance of land surfaces

Description

Total reflectance of built, cultivated and natural land surfaces. Data are to be used as "reference values only" as actual values will vary.

Usage

materials.mspct

Format

A reflector_mspct object named materials.mspct containing a collection of reflector_spct objects each with 491 rows and 2 variables.

The variables for each spectrum are as follows:#'

• w.length (nm)

• Rfr (fraction)

These member objects contain metadata stored as R attributes. Accessors to the metadata are available: what_measured(), how_measured(), when_measured(), and comment().
