UVI is an ultraviolet imager that is able to capture images with 365-nm wavelength and 283-nm wavelength to map SO2 and unknown absorber, respectively.
IR1 measures the thermal radiaion mostly from the surface and a little from the atmosphere using four filters, 0.90 μm (dayside), 0.90 μm (nightside), 0.97 μm, and 1.01 μm.
IR2 utilizes the atmospheric windows at wavelengths of 1.74, 2.26, and 2.32 μm; the first two suffer only CO2 absorption, while the last one contains a CO absorption band. At these wavelengths the outgoing infrared radiation originates from the altitudes 35 -- 50 km.
LIR detects thermal emission from the cloud top in a wavelength region 8 -- 12 μm to map the cloud-top temperature.
LAC searches for lightning flashes and maps airglow emissions on the nightside disk of Venus.
RS aims to determine the vertical structure of the Venusian atmosphere using radio occultation technique, which is achieved by using Ultra-Stable Oscillator (USO).
Orbit, attitude, and other required ancillary data are archived in SPICE kernels.
Planned release schedule is as follows:
