[en]利用毫米波探测大气和宇宙为我们提供了独特的科学课题。宇宙中最古老的毫米波信号是宇宙微波背景（CMB），它是大爆炸的残余。它的精确观测为我们提供了关于宇宙起源的知识。另一方面，大气辐射，即今天的毫米波信号，包含着暴雨的征兆。本文介绍了它们之间的技术协同。特别是，我们使用专利技术为CMB项目“GroundBird”开发了大气辐射监测仪“KUMODeS”，我们证明了它对这种气象应用是有用的。利用毫米波探测暗物质也是一个很有吸引力的科学课题。为此，我们新推出了名为“DOSUE-RR”的实验。（作者）
[en] Sensing of the atmosphere and the universe with millimeter waves provides us unique science topics. The oldest millimeter-wave signal in the universe is cosmic microwave background (CMB) which is the Big Bang’s remnant. Its precise observations provide us knowledge about the beginning of the universe. On the other hand, atmospheric radiation, ie, today’s millimeter-wave signal, contains signs of torrential rains. This article introduces technological synergy among them. In particular, we developed atmospheric radiation monitor “KUMODeS” using patent technologies for a CMB project “GroundBIRD”, and we demonstrated it is useful for such a meteorological application. Sensing dark matter with millimeter-wave is also an attractive science topic. We newly launched the experiment for this purpose, which is named “DOSUE-RR”.(author)
