Interpretation of Field Measurements Made with a Portable Albedometer

Abstract

A small portable albedometer with direct readout of albedo values is described. The instrument is designed for surveying natural fields on foot. It was used on glaciers in Austria and Greenland, not for precision measurements on the climatological stations, but as a correction for interpolated albedos between the stations. Results of these measurements will be published elsewhere. The interpretation of albedo measurements over nonuniform surfaces is discussed here.
