Abstract

Measurement of trace gases from satellite is useful technique to grasp the atmospheric information on a regional scale. In recent years, exhaust gas emitted by developing country has become a huge social issue. It greatly affects global environmental problems. In this study, we focused on Nitrous Oxide (N₂O) in East Asia. N₂O has a strong radiative forcing and has gotten a lot of attention as the greenhouse effect and ozone-depleting gases recently. We conducted the sensitivity analysis of N₂O using the infrared spectral radiances measured by Tropospheric Emission Spectrometer (TES), which was launched on NASA's EOS Aura satellite in July 2004. Based on these result, we selected retrieval channel and tried to retrieve the troposheric profile of N₂O. In this paper, we will present the preliminary result.
