Abstract. A method for calculating the broadband albedo of the Earth’s surface is proposed, which is used on the basis of two narrowband albedos calculated using signals from two AVHRR channels. It has been established that the Liang formula used to calculate the broadband albedo does not allow for the presence of an arbitrary functional relationship between the specified narrowband albedos. It is shown that the average integral value of the broadband albedo reaches a maximum value, i.e., unity, provided that one narrowband albedo is equal to unity, and the other is equal to 1.48. To eliminate this drawback, it is proposed to impose some restrictive condition on the specified relationship in the integral expression. The threshold value at which the known formula turns out to be correct is determined.
