Introduction to the Toolbox

A large component of this tool box concerns the use of BRDF/Albedo/NBAR products from MODIS/VIIRS and related MODIS/VIIRS products such as MOD08 the gridded atmospheric product for the calculation of diffuse light fraction for blue-sky albedo calcuation. However, as this toolbox grows through the evolution of MODIS/VIIRS products, we expect to add more tools to cover wider range of MODIS/VIIRS products.

Organization of the Toolbox

actual-albedo-tool

A vintage program to calculate the blue-sky albedo with either (1) weighted sum of BSA and WSA, or (2) full expression. To be updated for the latest M/V products.

common-utils

Tools that apply to both MODIS and VIIRS products including:

• Downloading M/V products from NASA test product ftps, and a few DAACs such as LAADS and LP.
• Generate preview images and stats of a given MCD43/VNP43 product file.
• Compare two MCD43/VNP43 product files and generate comparison figures and stats.

mcd43t-processing

Processing of internal MCD43T products for product testing.

modis-utils

Tools that apply to only MODIS products.

VIIRS-utils

Tools that apply to only VIIRS products.

data

Supporting data to run some of the tools.

ext

External dependencies (libraries and programs) to run some of the tools.
