IASI atmospheric spectra (L1C product) from the EPS Metop-B satellite: CEDA mirror archive for STFC, NCAS, NCEO

This dataset contains level 1C data products from the Infrared Atmospheric Sounding Interferometer (IASI) instrument onboard the Eumetsat EPS Metop-B satellite.

IASI was designed to measure the infrared spectrum emitted by the earth. IASI provides infrared soundings of the temperature profiles in the troposphere and lower stratosphere, moisture profiles in the troposphere, as well as some of the chemical components playing a key role in the climate monitoring, global change and atmospheric chemistry. The IASI L1c product contains infra-red radiance spectra at the 0.5cm-1 resolution, covering the range between 645.0 cm-1 and 2760 cm-1

This data set contains both the original processed data and reprocessed archive in the following directories based on processing algorithm. Please see information under the process tab for further information. Please note an erratum has been raised in relation to 2017 data please see the Ten-Year Assessment of IASI Radiance and Temperature in the documentation section.

本数据集收录了搭载于欧洲气象卫星组织（Eumetsat）EPS Metop-B卫星上的红外大气探测干涉仪（IASI）的一级C类数据产品。

IASI旨在测量地球发射的红外光谱。该仪器提供了对流层和下层平流层的温度廓线、对流层中的湿度廓线，以及在全球气候变化、大气化学监测中扮演关键角色的某些化学成分的红外探测。IASI L1c产品包含0.5cm^-1分辨率的红外辐射光谱，覆盖了645.0 cm^-1至2760 cm^-1的范围。

本数据集包含原始处理数据和基于处理算法的重处理档案数据，具体目录如下。请查阅“处理”标签下的信息以获取更多信息。请注意，关于2017年的数据已发布勘误，请参阅文档部分的“IASI辐射和温度十年评估”。
