1st special session's title

« Air Quality Monitoring from Big Earth Data »

1st special session's conveners
Prof. Yong Xue, University of Derby, UK.
Prof. Gerrit de Leeuw, FMI, Finland.
Prof. Ronald van der A, KNMI, The Netherlands.
1st special session's summary
Environmental pollution become more and more serious due to today’s development all around the world. Air pollution is one of the most important environmental problems, which concentrates mostly in cities. Air pollution has long been a problem in the industrial nations of the West. It has now become an increasing source of environmental degradation in the developing nations of Africa. Remote sensing has been widely used for environmental application such as for air quality and water quality studies. Earth observation satellites have developed with much higher spatial and spectral resolutions, and the data transmission speed and storage capacity are increasing accordingly. The amount of remote sensing data produced by airborne and spaceborne sensors is increasing at a rate of a terabyte per day, and a single data set can reach a gigabyte.
Although atmospheric remote sensing data can help estimate air pollution levels, these data have limitations especially if used on their own. Big Earth Data provides a new vision and methodology to Earth sciences. Big Earth Data is about using various different types of spatial geo-data and developing relevant tools within the overall context of a computational scientific approach. It is concerned with new computational techniques, algorithms, and paradigms to enhance the air quality monitoring that are dependent upon and can take advantage of Big Earth Data. This Special Session will offer presentations from a variety of sources, both local, national and international and will enable you to network with others working in similar fields.

It is especially focused on the dynamic changes of reginal area around the world. The preferred topics are the followings, but not limited to the methodologies, technologies, and new findings over hot-spots area revealed by multi-source series of high resolution remote sensing data.



3rd special session's title

« Water Cycle and Water Resource Management: Earth Observation Perspectives across Africa, Asia and Europe »

3rd special session's conveners
Prof. Li Jia, RADI-CAS, China.
Prof. Massimo Menenti, Delft University of Technology, The Netherlands.
Prof. Bob Su, University of Twente, The Netherlands.
3rd special session's summary
Global water demand, in comparison to the recent level of water withdrawals, is projected to increase by some 55% by 2050 because of growing demands from various sectors (OECD, 2012). The World Economic Forum identified in its Global Risks report (2013) water supply crises among the top two most impactful and top five most likely global risks.
The impact of climate change on water resources and management is one of the key scientific and social concerns of this century. Reliable access to water cannot be assured, while the effects of flooding and droughts are contributing to large human and socio-economic losses. In addition, large fluctuations of regional and local water cycles are a threat to water security and freshwater ecosystems. Water-related risks can be mitigated by using effectively the rich and timely information captured by earth observation.
The session will cover highlights of Earth Observation (EO) data products and information services to advance knowledge of the terrestrial water cycle, to assess water use and water – related natural hazards and to support effective water management systems.
The session aims at documenting an emerging perspective in this area where new partnerships, such as the Belt and Road Initiative, are changing the EO Water landscape in Africa, Asia and Europe through new ways of addressing multi – national challenges, e.g. drought, and new sources of EO data.
The panel discussion will target current research and development (R&D) opportunities and gaps towards addressing the EO Water challenges identified by the Session.



Title of the Side Event Workshop

« Introduction to SMAP: An Overview of the SMAP Mission and Data Access and Analysis »

Event convener
Dr. Erika Podest, JPL-NASA, USA.
Summary description
To provide an overview of the SMAP satellite mission and its soil moisture products enabling general knowledge of the instruments, the retrieval algorithms, the datasets, the calibration and validation program, and end user applications. A hands-on portion will allow participants to download, visualize and analyze SMAP data. The course is intended for scientists, students, and end users interested in using satellite-derived soil moisture or freeze/thaw data.
