[IEEE IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium - Valencia, Spain (2018.7.22-2018.7.27)] IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium - Validation of Global Land Surface Satellite Phase-2 Surface Broadband Albedo Product

摘要： Surface broadband albedo is a critical parameter in surface radiation budget (SRB), which controls the input, separation, and allocation of the Earth’s surface energy. Recently, a Global LAnd Surface Satellite (GLASS) phase-2 surface broadband albedo product has been generated from the Moderate Resolution Imaging Spectroradiometer (MODIS) and the Advanced Very High Resolution Radiometer (AVHRR) data. In this study, we present a preliminary validation of the GLASS phase-2 surface broadband albedo with the FLUXNET 2015 dataset. The results show that the GLASS phase-2 surface broadband albedo product has a reasonable good accuracy compared with the currently widely used surface albedo dataset, and can provides more reliable estimations of surface albedo at the seasonal snowfall and snowmelt regions. In addition, the GLASS phase-2 surface albedo product is a long-term, global covered (including land and ocean surfaces) dataset, which can be applied in various scenarios of SRB and climate change studies.
