[MSD42-10] High-frequency observations of water vapor, isotope, ice clouds and radiation budget by FTS small satellite constellation
Keywords:small satellite constellation, Fourier Transform Spectrometer, water vapor
The purpose of this mission is not only a quantitative understanding of the Earth's radiation balance, but also to improve the forecast accuracy of a meteorological disaster through an understanding of the precipitation process and atmospheric disturbances by the high frequency observation of the water vapor, its isotopes and ice clouds in the troposphere and stratosphere.
In the observation, multiple small Fourier-Transform Spectrometer (FTS) aircrafts (100 kg class) (40 aircrafts in the future) will be used to observe the East Asian region including Japan at intervals of about one hour. The observation wavelength range is in the far infrared region (100 to 670 cm-1; 15 to 100 μm), and a resolution of 0.1 cm-1 is assumed. The satellite is expected to have an orbital inclination of 38 degrees, an altitude of 200 to 300 km, a vertical resolution of 3 km, and a Swath of 40 km at nadir viewing.
It will also serve as an effectiveness and verification of FTS measuring instruments in the infrared region for mounting on geostationary meteorological satellites in the future.
