Greenhouse Gases Observing Satellite-2

Greenhouse Gases Observing Satellite-2 is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Greenhouse Gases Observing Satellite-2 rather than just read about it. In short: The Greenhouse Gases Observing Satellite-2 (GOSAT-2), also known as Ibuki-2 (Japanese: いぶき2号, Hepburn: Ibuki nigō), is an Earth observation satellite dedicated to greenhouse gas monitoring. It is a successor of Greenhouse Gases Observing Satellite (GOSAT).

Key takeaways

Greenhouse Gases Observing Satellite-2 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Greenhouse Gases Observing Satellite-2 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Greenhouse Gases Observing Satellite-2 from memory before moving on to harder problems.

Reference excerpt

The Greenhouse Gases Observing Satellite-2 (GOSAT-2), also known as Ibuki-2 (Japanese: いぶき2号, Hepburn: Ibuki nigō), is an Earth observation satellite dedicated to greenhouse gas monitoring. It is a successor of Greenhouse Gases Observing Satellite (GOSAT). The GOSAT-2 was developed as a joint project of the Japan Aerospace Exploration Agency (JAXA), Ministry of the Environment, and the National Institute for Environmental Studies (NIES). It was launched on 29 October 2018 from the Tanegashima Space Center aboard the H-IIA rocket.

Comparison to GOSAT Major changes in comparison to the previous GOSAT are:

Improved measurement precision. FTS-2 can also monitor carbon monoxide (CO) and nitrogen dioxide (NO2). FTS-2 can select cloud-free point automatically for observation. While GOSAT's CAI was observing nadir view, GOSAT-2's CAI-2 observes forward (20 degree) and backward (20 degree) simultaneously. CAI-2 can also monitor PM2.5 and black carbon.

Successor: GOSAT-GW GOSAT-GW (Ibuki GW), the successor of GOSAT-2 and GCOM-W "Shizuku", was launched on 28 June 2025 on the last flight of the H-IIA launch vehicle. It was under development for launch in JFY2024. Due to the delay of development, it was delayed to be launched in JFY2025.

Worked examples

Example 1 — a first encounter with Greenhouse Gases Observing Satellite-2

Start with the simplest possible case. Write down what Greenhouse Gases Observing Satellite-2 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Greenhouse Gases Observing Satellite-2 before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Greenhouse Gases Observing Satellite-2 ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Greenhouse Gases Observing Satellite-2

In research: Greenhouse Gases Observing Satellite-2 appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Greenhouse Gases Observing Satellite-2 in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Greenhouse Gases Observing Satellite-2 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Earth observation satellites of Japan, Greenhouse gases, JAXA, so understanding it makes those chapters shorter.
In everyday life: Look for Greenhouse Gases Observing Satellite-2 outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
