The Yareelo (also Yarilo) №3, №4 (CubeSats 3U) are designed for helio- geophysics research. Yareelo № 3 and 4 are equipped the MIRA sensors, developed by IZMI RAS, for measuring the energy reflected from the Earth (the albedo of the Earth). Measurements are carried out in two spectral ranges 0.2-5 microns and 0.2-50 microns with a sensitivity of 0.15+/-0.05 A/W. The obtained data make possible to assess the indicators affecting global warming.
