Experiment/Payload Overview

Information provided courtesy of the Japan Aerospace and Exploration Agency (JAXA) Brief Summary

Superconduction Submillimeter-wave Limb-emission Sounder (SMILES) is aimed at global mappings of stratospheric trace gases by means of the most sensitive submillimeter receiver. Such sensitivity is ascribed to a Superconductor-Insulator-Superconductor (SIS) mixer, which is operated at 4.5 K in a dedicated cryostat combined with a mechanical cooler.

    Experiment/Payload Description

    Research Summary

    • Superconduction Submillimeter-wave Limb-emission Sounder (SMILES), is aimed at global mappings of stratospheric trace gases by means of the most senseitive submillimeter receiver.


    • Such sensitivity is ascribed to a Superconductor-Insulator-Superconductor (SIS) mixer, which is operated at 4.5 K in a dedicated cryostat combined with a mechanical cooler.


    • SMILES will observe ozone-depletion-related molecules such as ClO, HCl, HO2, HNO3, BrO and O3 in the frequency bands at 624.32-626.32 GHz and 649.12-650.32 GHz.


    • A scanning antenna will cover tangent altitudes from 10 to 60 km in every 53 seconds, while tracing the latitudes from 38 S to 65 N along its orbit.


    • This global coverage makes SMILES a usuful tool of observing the low- and mid-latitudinal areas as well as the Arctic peripheral region.

    Earth Applications

    SMILES data will enable us to investigate the chlorine and bromine chemistry and the HOx chemistry around the polar vortex region and over the equatorial and mid-latitude regions. SMILES mission also provides a database for ozone variations in time and position around the upper troposphere and lower stratosphere (UT/LS).
