The advanced microwave radiometer-climate quality (AMR-C) is a part of the European Sentinel-6A/B series, a collaboration between ESA and NASA, of two Earth-observing satellites, which will be launched in 2020 and 2025. Compared to its predecessor, Jason-3, the two AMR-C radiometer instruments have an external calibration system which enables higher radiometric stability accomplished by moving the secondary mirror between well-defined targets. Sentinel-6 allows continuing the study of the ocean circulation, climate change, and sea-level rise for at least another decade. Besides the external calibration for the AMR heritage radiometer (18.7, 23.8, and 34 GHz channels), the AMR-C contains a high-resolution microwave radiometer (HRMR) with radiometer channels at 90, 130, and 168 GHz. This subsystem allows for a factor of 5× higher spatial resolution at coastal transitions. This article presents a brief description of the instrument and the measured performance of the completed AMR-C-A and AMR-C-B instruments.

完成 Sentinel-6 的 AMR-C 仪器

先进的微波辐射计气候质量 (AMR-C) 是欧洲 Sentinel-6A/B 系列的一部分，该系列是 ESA 和 NASA 合作的两颗地球观测卫星，将于 2020 年和 2025 年发射。其前身 Jason-3，这两个 AMR-C 辐射计仪器具有外部校准系统，通过在明确定义的目标之间移动次镜来实现更高的辐射稳定性。Sentinel-6 允许继续研究海洋环流、气候变化和海平面上升至少十年。除了对 AMR 遗产辐射计（18.7、23.8 和 34 GHz 通道）进行外部校准外，AMR-C 还包含一个高分辨率微波辐射计 (HRMR)，其辐射计通道位于 90、130 和 168 GHz。该子系统允许在沿海过渡时将空间分辨率提高 5 倍。本文简要介绍了该仪器以及已完成的 AMR-CA 和 AMR-CB 仪器的测量性能。
