soilparamsp: A dataset of vegetation parameters.

soilparamspR Documentation

A dataset of vegetation parameters.

Description

An object of class vegparams for the area for the area bounded by 169475, 169525, 12475, 12525 (xmin, xmax, ymin, ymax) using the Ordnance Survey GB Grid Reference system (CRS: 27700).

Usage

soilparamsp

Format

A list of the following objects:

pai

a PackedSpatRaster of monthly plant area index values, 12 layers

hgt

a PackedSpatRaster object of vegetation heights (m)

x

a PackedSpatRaster object of the ratio of vertical to horizontal projections of leaf foliage

gsmax

a PackedSpatRaster object maximum stomatal conductances (mol / m^2 / s)

leafr

a PackedSpatRaster object of leaf reflectance values

clump

a PackedSpatRaster of monthly values between 0 and 1 indicating the fraction of radiation passing through larger gaps in the canopy, here estimated using [clumpestimate()], 12 layers
