It is demonstrated within the frameworks of the analysis of determination methods of snowice cover reflectance that the problem of the measurement technique of hummocky formation albedo has not been studied enough. The results of in situ experiments carried out on the Arctic sea ice are presented. The results of ice hummock albedo measurements using different techniques are discussed. The need to organize the special experimental research for the development of practical recommendations for estimating the hummocky formation albedo is declared.
