This data set comprises 8-daily values of the gridded global land surface albedo derived from MODIS reflectance values observed at bands 1-7 for periods of 16 days; successive 16-day periods overlap by 8 days. Depending on the availability data from EOS-AQUA and/or EOS-TERRA are used.
We are offering the data set with a spatial resolution of 0.05° (about 5600 m). The data set is also available with 1000 m and 500 m spatial resolution (see LPDAAC Website (seach for albedo)).
This is data set version 005.
We recommend the EOS-Data hand book for further reading.

The data offered here are in netCDF format. These include, in addition to the white sky albedo (reflection of diffuse radiation) its difference to the black sky albedo (reflection of direct radiation), quality flags which give information about the quality of the inversion, and the percentage number of high-resolution data per grid cell that were used for this product.
Original data are available in HDF-EOS Format. These data include in addition the reflectance values for each channel, the white & black sky albedo calculated separately for the visible and near infrared part of the spectrum, the solar zenith angle, and the percentage snow cover.
