IASI stands for Improved Atmospheric Sounding Interferometer. It is an instrument used in meteorology to gather data about the Earth’s atmosphere. The IASI instrument is part of the Metop satellite series, which are operated by the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT).
The main purpose of IASI is to measure the atmospheric concentration of various gases and to provide high-resolution temperature and humidity profiles. This information is essential for weather forecasting, climate research, and monitoring of atmospheric composition. IASI works by measuring the infrared radiation emitted by the Earth and its atmosphere, which can be used to determine the concentration of different gases.
One of the key advantages of IASI is its ability to provide global coverage and high spatial resolution. It can measure atmospheric variables with a horizontal resolution of 12 km and a vertical resolution of 1 km. This level of detail allows meteorologists to better understand atmospheric processes and improve the accuracy of weather forecasts.
In addition to its meteorological applications, IASI data is also used for other scientific research. For example, it can be used to study the distribution of greenhouse gases, such as carbon dioxide and methane, and their impact on climate change. The data collected by IASI is freely available to the scientific community and is used in various research projects around the world.
In conclusion, IASI is an important instrument in meteorology that provides valuable data about the Earth’s atmosphere. Its high-resolution measurements help improve weather forecasts, climate research, and the study of atmospheric composition. The data collected by IASI is a valuable resource for scientists and researchers working in various fields.
