About Greenhouse gases Observing SATellite-2 "IBUKI-2" (GOSAT-2)

Taking over from IBUKI to enhance the functionality and performance of greenhouse gas observations

Experts say that greenhouse gases produced by human activity represent one of the biggest causes of global warming. The Intragovernmental Panel on Climate Change (IPCC), an international organization of specialists that conducts scientific research on climate change and evaluates related climate policies, released its Fifth Assessment Report in 2013. In the document, the authors warned that “Warming of the climate system is unequivocal... It is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century... Continued emissions of greenhouse gases will cause further warming and changes in all components of the climate system.”
Hoping to advance research on the global warming phenomenon, JAXA has joined forces with the Ministry of the Environment and the National Institute for Environmental Studies to develop “IBUKI” (GOSAT) - the Greenhouse gases Observing SATellite - and commence GOSAT-based observations of carbon dioxide and methane in 2009. Prior to the creation of the IBUKI, researchers struggled with obtaining accurate, consistent data for comparison purposes due to the limited observation scope and the fact that different countries gathered observation data at different levels of precision and tabulated the results via different methods. The IBUKI, however, made it possible to get an accurate map of carbon dioxide and methane concentrations around the globe.
As the successor to the IBUKI mission,  "IBUKI-2" (GOSAT-2) aims to gather observations of greenhouse gases with higher levels of accuracy via even higher-performance onboard observation sensors. The project will serve to provide observation data to environmental administrations and drive international anti-global warming efforts.

Characteristics of Greenhouse gases Observing SATellite-2 "IBUKI-2" (GOSAT-2)

 

The IBUKI-2 “eye”: An upgraded IBUKI
The IBUKI observed carbon dioxide and methane at accuracy levels of 4 ppm (*1) and 34 ppb (*2) , respectively, at a 1,000-km mesh. In order to generate even more precise data, the goals for the GOSAT-2 are to measure carbon dioxide at 0.5 ppm and methane at 5 ppb at a 500-km mesh.
Developers have also enhanced the satellite’s focused, target-point observation capabilities (target-point observation functionality), enabling the device to gather accurate readings from a broader range of target points - an ability that will be especially beneficial in evaluations of industrial areas, densely populated areas, and other areas with large quantities of greenhouse gas emissions.
*1 ppm is a unit that shows“parts per million”; 1 ppm is equivalent to 0.0001%.
*2 ppb is a unit that shows“parts per billion”; 1 ppb is equivalent to 0.001 ppm or 0.0000001%.

Anthropogenic source or natural source? Carbon monoxide can determine
In another improvement over its predecessor, the IBUKI-2 is also capable of monitoring carbon monoxide concentrations. Whereas carbon dioxide not only comes from anthropogenic sources like industrial activity and fuel combustion but also has natural origins in forests and biological activity, carbon monoxide emissions are byproducts of human activity alone – not the natural world. Analyzing combined observations of carbon dioxide and carbon monoxide will give researchers an effective means of estimating carbon dioxide emissions from anthropogenic sources.

PM 2.5: A new health hazard
Airborne PM 2.5 has become an increasingly concerning health hazard. The GOSAT-2 will help monitor PM 2.5 by gathering the data that scientists need to estimate PM 2.5 concentration levels.

KhalifaSat: a nation poised to explore the oceans of space

Monday's launch of the first Emirati-designed satellite will mark a brave step into the future for the UAE

With the launch of the KhalifaSat observation satellite on Monday morning, the UAE will demonstrate literally and metaphorically that not even the sky is the limit for a nation that aspires to be counted among the greatest on Earth by the time it celebrates its golden jubilee in 2021. Much has been written about the astonishing pace of development in the UAE, but at a historic moment like this, it bears repeating. In a single lifetime the peoples of the seven emirates have not only broken free of the shadow of centuries of harsh subsistence to claim their place on the sunlit uplands of the modern world, but have lifted their gaze from the terrestrial horizon and set their sights on space.

KhalifaSat is not the first satellite to carry the UAE flag – eight commercial vehicles have been put into orbit since 2011. But as the first to be built entirely by UAE engineers, KhalifaSat represents a significant milestone in the nation’s fast-moving ambitions. The UAE Space Agency was established only four years ago. Next year, the first Emirati astronaut will blast off, bound for the International Space Station. In 2021, the Emirates Mars Mission will land a UAE-built probe on the red planet – the first Arab expedition to another world. Such is the unbridled confidence of this nation that by 2117 the UAE even aims to have established the first human settlement on Mars.

Exploring space has obvious practical and commercial benefits, placing the UAE at the cutting edge of technology and contributing much to the ambition of Vision 2021 to create a resilient, knowledge-based economy in a post-oil world. But space travel has never been about the merely practical. The UAE’s great adventure raises a banner of hope and optimism that serves as a catalyst for educational excellence and technical achievement, not just in the UAE but in the wider Arab world.

In holding out the promise of a better future, it also honours a long-neglected scientific legacy that extends back to the Islamic golden age. After all, no fewer than 24 of the craters of the Moon are named after the great Arab scholars of the past, from the ninth-century Mesopotamian astronomer Muḥammad Al Battani to the 14th century Moroccan geographer Ibn Battuta. For centuries, the most technically advanced form of transport in the land that in 1971 became the UAE was the dhow, the simple tool that made existence possible for the generations of Emiratis whose often harsh and perilous existence was dependent upon fishing and pearl diving. Today, their descendants are setting sail on what President John F Kennedy called the great ocean of space, launching spacecraft, training astronauts and preparing to explore other planets. Now that is what you call a giant leap.
