Ibuki and oco should provide a better idea of what happens to carbon dioxide once it is produced .

二氧化碳一旦产生，ibuki和oco就会帮助我们更好解释它们的去向。

Oco will similarly study carbon dioxide and also oxygen signatures in reflected sunlight . It will fly at an average altitude of 705km and orbit the earth about every 99 minutes .

同样，oco也会研究太阳反射光线中的二氧化碳和氧气特征光谱，它将于705公里的上空以99分钟绕地球一圈的速度飞行。

Later this month the american space agency , nasa , is due to launch the orbiting carbon observatory ( oco ) , which is also designed to monitor carbon dioxide .

本月晚些时候美国航空航天局（nasa）也将发射一颗用于监测二氧化碳的“嗅碳”卫星（oco）。

In january the japanese space agency , jaxa , launched ibuki , the first satellite dedicated to monitoring carbon dioxide and methane . Later this month the american space agency , nasa , is due to launch the orbiting carbon observatory ( oco ) , which is also designed to monitor carbon dioxide .

1月，日本航天局jaxa发射了第一颗专门监测二氧化碳和甲烷的卫星ibuki；本月晚些时候，美国航天局nasa也将发射轨道碳观测卫星（oco），目的同样是监测二氧化碳。
