IMK/IAA generated MIPAS/Envisat data

The Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) onboard the ENVISAT satellite provided atmospheric infrared limb emission spectra. From these, profiles of temperature and atmospheric trace gases were retrieved using the research data processor developed at the Institut für Meteorologie und Klimaforschung (IMK), which is complemented by the component of non-local thermodynamic equilibrium (non-LTE) treatment from the Instituto de Astrofísica de Andalucía (IAA). The MIPAS data products on this server are commonly known as IMK/IAA MIPAS Level2 data products. The MIPAS instrument measured during two time frames: from 2002 to 2004 in full spectral resolution (high resolution = HR aka full resolution = FR), and from 2005 to 2012 in reduced spectral, but improved spatial resolution (reduced resolution = RR aka optimized resolution = OR). For this reason, there are different version numbers covering the full MIPAS mission period: xx for the HR/FR period, and 2xx for the RR/OR period (example: 61 for HR/FR, 261 for RR/OR). Beyond this, measurements were conducted in different modes covering different altitude ranges during the RR period: Nominal (6 – 70 km), MA (18 – 102 km), NLC (39 – 102 km), UA (42 – 172 km), UTLS-1 (5.5 – 19 km), UTLS-2 (12 – 42 km), AE (7 – 38 km). The non-nominal modes are identified by the following version numbers: MA = 5xx, NLC = 7xx, UA = 6xx, UTLS-1/2 = 1xx (no retrievals for AE mode).

搭载ENVISAT卫星的米歇尔干涉仪（Michelson Interferometer for Passive Atmospheric Sounding，简称MIPAS）提供了大气红外边缘发射光谱。基于这些光谱，通过在德国气象与气候研究所（Institut für Meteorologie und Klimaforschung，简称IMK）开发的科研数据处理器，成功获取了温度和大气痕量气体的剖面数据。该研究所的成果得到了西班牙安达卢西亚天文物理研究所（Instituto de Astrofísica de Andalucía，简称IAA）提供的非局部热力学平衡（non-local thermodynamic equilibrium，简称non-LTE）处理组件的补充。本服务器上的MIPAS数据产品通常被称为IMK/IAA MIPAS Level2数据产品。MIPAS仪器在两个时间框架内进行了测量：2002年至2004年以全光谱分辨率（高分辨率 = HR，即全分辨率 = FR）进行测量，以及2005年至2012年在降低光谱分辨率但提高空间分辨率（降低分辨率 = RR，即优化分辨率 = OR）的情况下进行测量。因此，针对MIPAS任务的全周期，存在不同的版本号：xx代表HR/FR周期，2xx代表RR/OR周期（例如：61代表HR/FR，261代表RR/OR）。此外，在RR周期内，针对不同的高度范围进行了不同模式的测量：标准模式（6 – 70 km），MA模式（18 – 102 km），NLC模式（39 – 102 km），UA模式（42 – 172 km），UTLS-1模式（5.5 – 19 km），UTLS-2模式（12 – 42 km），AE模式（7 – 38 km）。非标准模式通过以下版本号进行标识：MA模式 = 5xx，NLC模式 = 7xx，UA模式 = 6xx，UTLS-1/2模式 = 1xx（AE模式不进行数据检索）。
