This information has been recorded on the ERB 'Sub-Target Radiance Tapes' (STRT). A description of that data base and procedures for obtaining the data may be found in Stowe and Fromm (1983). Selected data from the STRTs have been sorted into eight uniform earth and cloud surface types. Diagrams illustrating the bi-directional reflectivity of these surfaces have been constructed. Several of these diagrams have already been published in a paper by Taylor and Stowe (1984). That paper is included as appendix A of this report to provide a complete discussion of: (1) how these diagrams can be interpreted; (2) why they are important and useful; (3) how they compare with other empirical and theoretical results and (4) the methods of diagram construction. The paper also discusses the observed dependence of albedo on solar zenith angle (SZA) and includes figures illustrating this dependence. An extensive list of references is also given. This report contains a complete set of reflectance diagrams (patterns) and tables listing the values that were used in their construction and interpretation. 收起
