DMSP SSM/I-SSMIS Daily Polar Gridded Brightness Temperatures, Version 2

This data set provides daily gridded brightness temperatures derived from passive microwave sensors and distributed in a polar stereographic projection. Orbital data from nine channels and for each 24-hour period are mapped to respective grid cells using a simple sum and average method (drop-in-the-bucket method).本数据集提供由被动微波传感器反演得到的逐日网格化亮温数据，采用极地方位投影（polar stereographic projection）格式进行存储与分发。针对9个通道且对应每24小时时段的轨道观测数据，本数据集通过简单求和平均法（亦称桶内丢弃法，drop-in-the-bucket method）将其映射至对应的网格单元。
