MSG Daily Surface Albedo (MDAL-R)

GET DATA HERE

Land surface albedo is a key variable for characterising the energy balance in the coupled soil-vegetation-atmosphere system. The albedo quantifies the part of the energy that is absorbed and transformed into heat and latent fluxes. Owing to strong feedback effects the knowledge of albedo is important for determining weather conditions at the atmospheric boundary layer. Climate sensitivity studies with Global Circulation Models have confirmed the unsteady nature of the energy balance with respect to small changes in surface albedo. Other domains of applications are in hydro-meteorology, agro-meteorology and environment-related studies.

 

Product Documentation

The characteristics and file format of this demonstration Data Record are the same as its correspondent NRT product.  It is documented in the following documents:

Please see Product Peer-Review publications in References.

Here you will find the daily Albedo averaged per month over the 2004-2019 period.

This dataset was derived by joining the MDAL CDR (MDAL-R) for 2004-2015 and the operational NRT product (MDAL, LSA-101) for 2016-2019.

This NetCDF files contain the Bi-Hemispherical and Directional-Hemispherical Albedo averaged over all days of "December", for the 2004-2019 period. The datasets are available on a regular 0.05º grid and the files' format is fully CF-compliant.

The MSG mission (in operations since 2004) already provides a relatively long time series of VIS and IR observations over the full Earth Disk centred at 0º. The full archive of MSG/SEVIRI data was reprocessed to provide the user comunity a consistent, homogeneous and continuous Data Record of the Daily Surface Albedo (MDAL) for the period 2004-2015. 

This Data Record was obtained with the best version of its equivalent NRT product (MDAL) which can also complement the time series from 2016 onwards.
