一个新的最先进的气球载三通道（500，625，1800千兆赫）低温外差光谱仪将允许在亚毫米和远红外光谱范围内增强地球大气层的临边探测。该仪器名为TELIS（太赫兹和亚毫米LIMB探测器），由欧洲主要研究所组成的一个联合体开发，其中包括荷兰空间研究组织、联合王国的卢瑟福·阿普尔顿实验室和德国的德国航空航天中心（牵头研究所）。TELIS将采用最先进的超导外差技术，设计紧凑，重量轻，同时提供宽光谱覆盖，高光谱分辨率和长飞行时间（单次飞行活动期间约24小时）。高灵敏度和广泛的飞行时间相结合，将允许调查的昼夜变化的关键大气短寿命的自由基，如OH，HO 2，ClO，BrO连同稳定的成分，如O3，HCl和HOCl。此外，TELIS将与德国卡尔斯鲁厄大学气象和气候研究所开发的MIPAS-B傅里叶变换光谱仪共用一个气球平台。MIPAS-B将在扩展的光谱范围内提供同步和互补的光谱测量。TELIS和MIPAS仪器的结合将为大气科学家提供一个非常强大的观测工具，此外，还将作为未来空间仪器的前奏。
A new state-of-the-art balloon borne three channel (500, 625, 1800 GHz) cryogenic heterodyne spectrometer will allow enhanced limb sounding of the Earths atmosphere within the submillimeter and far-infrared spectral range. The instrument, called TELIS (TErahertz and submm LImb Sounder), is being developed by a consortium of major European institutes that includes the Space Research Organisation of the Netherlands (SRON), the Rutherford Appleton Laboratory (RAL) in the United Kingdom and the Deutschen Zentrum fur Luft- und Raumfahrt (DLR) in Germany (lead institute). TELIS will utilise state-of-the-art superconducting heterodyne technology and is designed to be compact and lightweight, while providing broad spectral coverage, high spectral resolution and long flight duration (~24 hours duration during a single flight campaign). The combination of high sensitivity and extensive flight duration will allow investigation of the diurnal variation of key atmospheric short-lived radicals such as OH, HO2, ClO, BrO together with stable constituents such as O3, HCl and HOCl. Furthermore, TELIS will share a balloon platform with the MIPAS-B Fourier transform spectrometer, developed by the Institute of Meteorology and Climate Research of the University of Karlsruhe, Germany. MIPAS-B will provide simultaneous and complementary spectral measurements over an extended spectral range. The combination of the TELIS and MIPAS instruments will provide atmospheric scientists with a very powerful observational tool and, in addition, will act as a prelude to future spaceborne instruments.
