Abstract
The concept of a high aperture near-infrared cross-dispersion echelle-spectrometer is presented for greenhouse gases remote measurements from space. This task is of a global nature, industrial and household emissions are anthropogenic sources of greenhouse-gas emissions. In recent years, average levels of carbon (CO2) and methane (CH4) have continued to increase, reaching levels of 410 ppm and 1877 ppb, respectively, to date. Obtaining objective information about the state of the carbon balance in the atmosphere is possible only with the use of space-based instruments. The Driada instrument consists of three channels. The main one is a high-resolution spectrometer for the 1.4- to 1.67-μm wavelength range and is designed to measure CO2 absorption lines at 1.58 and 1.6 μm, CH4 lines at 1.65 μm, and a number of H2O lines. Two additional channels are designed to measure the O2 band at 0.76 μm and aerosol characterization. The scientific tasks and key parameters of the main infrared channel are discussed.
期刊介绍：
Cosmic Research publishes scientific papers covering all subjects of space science and technology, including the following: ballistics, flight dynamics of the Earth’s artificial satellites and automatic interplanetary stations; problems of transatmospheric descent; design and structure of spacecraft and scientific research instrumentation; life support systems and radiation safety of manned spacecrafts; exploration of the Earth from Space; exploration of near space; exploration of the Sun, planets, secondary planets, and interplanetary medium; exploration of stars, nebulae, interstellar medium, galaxies, and quasars from spacecraft; and various astrophysical problems related to space exploration. A chronicle of scientific events and other notices concerning the main topics of the journal are also presented.
