Num_Parameters_01\"，“BRDF_Albedo_Parameters_nn. Num_Parameters_02“和“BRDF_Albedo_Parameters_nn. Num_Parameters_03”波段，参考MODIS官方算法，计算得出白天反照率和夜间反照率，乘以比例因子0.001。\n\n数据质量：空间分辨率为500m×500m，时间分辨率为8天，每个像元的值为八天地表反照率的平均值。\n\n数据应用成果：作为重要参数可反演地表蒸散发。","doi":"","projection":null,"language":"zh","share_type":"online","east":78.21,"west":53.37,"south":33.48,"north":47.12,"scale":null,"crs":null,"filesize":1052.0,"share_policy":"a","ts_created":"2021-12-24T21:29:14.536263+08:00","doi_type":"国际公开共享数据","ts_updated":"2021-12-24T21:42:40.053806+08:00","time_description":"","datas_group":3,"time_description_en":"","data_format":null,"project":[11],"specials":[],"cite":null,"review_status":5,"review_invite":[{"user_name":"周彦昭","username":"小昭","email":"zhouyanzhao9@126.com","is_cancel_expert":false}],"review_editor":{"id":42421,"last_login":"2022-04-08T15:16:51.670544+08:00","username":"任慧霞","email":"510727846@qq.com","is_active":true,"is_staff":true,"user_name":"任慧霞"},"data_sources":null,"temporal_resolution":"Daily","spatial_resolution":"100m - 1km","license":"Attribution-NonCommercial-ShareAlike 4.0 International (CC BY-NC-SA 4.0)","fund":[6],"subtopics":{"metadata":"989b9419-f203-41cf-970a-d5189b2b4f1c","three_pole":null,"third_pole":"XDA20060303"},"username":"XDA20060303","review_time":null,"protected_duration":null,"protected_describe":null,"is_important":false,"hit_count":99}
