Diffuse reflectance of soils from Brazil

Source: R/soil_refle.R
soil_refle.Rd

A cleaned and organized diffuse reflectance database. The structure of the database includes the first column as the wavelength used in all samples, with the remaining columns representing the soil samples (Frosi et al., 2025).

Usage

soil_refle

Format

A data frame with 4241 rows and 24 columns:

wavelength_nm

Wavelength values in nanometers.

a1, a2, a3, a4, a5, a6, a7, a8, a9, a10, a11, a12, a13, a14, a15, a16, a17, a18, a19, a20, a22, a24, a26

Reflectance percentage (%R) corresponding to each for each soil sample.
