Summary
Africa Matthews Seasonal Albedo Example (Summer, Winter, Spring) was
developed by the World Data Center-A (WDC-A) for Solid Earth
Geophysics, operated by the US National Geophysical Data Center
(NGDC). The data set is part of the World Data Bank II and is part of
"The Global Change Data Base". The World Data Bank II is part of a
larger project called "Global ... Ecosystems Database Project". The
project is a joint effort between the National Oceanic and Atmospheric
Administration (NOAA), NGDC and the US Environmental Protection Agency
(EPA). The National Center for Geographic Information and Analyses
(NCGIA) in Santa Barbara, California joined the project to assist with
training and evaluation. A nominal 10 arc-minute scale was chosen to
provide compatibility with other scales and because this corresponds
closely with the resolution of global AVHRR coverage. All data are
provided in geographic (longitude/latitude) projection. The dataset
is accompanied by an ASCII documentation file which contains
information necessary for use of the dataset in a GIS or other
software.

The Africa integrated surface-albedo data sets (January, April, July,
October) are for snow-free conditions, incorporating natural
vegetation and cultivation characteristics from the vegetation types
and cultivation-intensity data sets.
