03-Albedo difference.gif

Figure “Seasonal difference in albedo” .

AveAlbedo.csv

File used to produce figure “Average monthly terrestrial albedo”. The file has average albedo values based on the calendar years 1986 to 1989. The values are average albedo on a 5 degree grid for the whole world (with some gaps near the poles) and a separate column of the average for each latitude. The file has 77 rows, 146 columns and contains 10125 non-blank items.

DiffAlbedo.csv

File used to produce figure “Seasonal albedo”. For each calendar month from 1986 to 1989 the albedo was averaged of all longitudes for each latitude. The values in the file are maximum difference in albedo for each latitude. The file has 2 columns, 77 rows and 131 non-blank items.

Monthly albedo.csv

File used to produce figure “Average albedo by latitude”. The file contains average albedo values for each calendar month from 1986 to 1989. Date is given in two formats to facilitate plotting. The file has 4 columns, 52 rows and 192 non-blank items.
