Description
The absorptivity of cellulose was inverted by Jacquemoud et al. (1996) from
a large database of leaf reflectance and transmittance using a two stream
model. The retrieved absorptivity was then normalized by the cellulose +
lignin dry mass per leaf area (g / m^2), resulting in the mass specific
absorption coefficient (m^2 / g). Since the results of Jacquemound et al.
(1996) were retrieved with a model based on the Kubelka-Munk theory, the
values are scaled by 2 to be used with radiative transfer theory (Ganapol et
al. 1999).
Usage

Format
An object of class data.frame with 421 rows and 2 columns.
Details
A similar spectral shape was determined by Dawson et al. (1998), but requires
scaling and offset to match the values of Jacquemoud et al. (1996) as used by
Fournier et al. (2018) to invert macrophyte properties.
