GlobAlbedo

Global Land Surface Albedo from Satellite Data

The GlobAlbedo project is developing a broadband albedo map of the entire Earth's land surface, which is required for use in climate modelling and research. An initial group of eight users are working with the GlobAlbedo project team to define requirements and drive the project towards practical applications of the products. The final albedo products will include both black and white sky albedo over the entire globe with at least monthly frequency over the 1995-2010 time period, and including uncertainty estimates.

 Objectives

The objective of the GlobAlbedo project is to respond to the users' requirements for a long time series of global land surface albedo by performing the following activities:

1. Developing and delivering a multi-annual global albedo data set that has the potential to be sustained into the future using data from operational European satellites, such as the GMES Sentinels.

2. Validating and intercomparing the albedo product against ground based, airborne and other satellite based measurements.

3. Providing the global user community with free access to the albedo products.

4. Demonstrating the utility of the albedo product by performing a scientific study exploiting the data set produced.

With the aim of deriving independent estimates making the best use of operational
European satellites, GlobAlbedo sets out to create a 15 year time series by employing
ATSR-2, SPOT4- VEGETATION and SPOT5-VEGETATION2 as well as AATSR and
MERIS.  Albedo retrieval will use an optimal estimation approach, as well as a novel
system for gap-filling.
