We describe the two 140-mm-aperture simulated blackbody sources used for the on-board calibration of the Along Track Scanning Radiometer, a spaceborne thermal infrared instrument for the accurate remote sensing of sea surface temperature, in operation since 1991. The design of these spaceborne sources, which operate at ≈ -10 °C and ≈ +30 °C, allows them to meet their unprecedented accuracy goal, namely a 3σ uncertainty in their brightness temperature of <0.1 K for the whole mission. This performance is empirically demonstrated in the laboratory and in flight by long-term temperature readout tests, temperature uniformity measurements, and direct emissivity measurements.
我们描述了两个140毫米孔径的模拟黑体源，它们用于沿轨扫描辐射计的在轨校准。沿轨扫描辐射计是一种自1991年起投入使用的星载热红外仪器，用于精确遥感海面温度。这些星载源的工作温度约为-10°C和约+30°C，其设计使其能够实现前所未有的精度目标，即在整个任务期间，其亮度温度的3σ不确定度小于0.1K。通过长期温度读数测试、温度均匀性测量和直接发射率测量，在实验室和飞行中都通过实验证明了这种性能。
