SMAP L1B Radiometer Half-Orbit Time-Ordered Brightness Temperatures, Version 3

This Level-1B (L1B) product provides calibrated estimates of time-ordered geolocated brightness temperatures measured by the Soil Moisture Active Passive (SMAP) passive microwave radiometer. SMAP L-band brightness temperatures are referenced to the Earth's surface with undesired and erroneous radiometric sources removed.

本1级B（Level-1B, L1B）产品提供了由土壤湿度主动被动（Soil Moisture Active Passive, SMAP）被动微波辐射计所测得的经校准的按时间排序的地理定位亮温估算值。SMAP的L波段亮温以地球表面为参考基准，并已去除非预期及错误的辐射源信号。
