Title: Area between Peaks Feature in the Derivative Reflectance Curve as a Sensitive Indicator of Change in Chlorophyll Concentration
Eric Ariel L. Salas, Geoffrey M. Henebry
Abstract: Vegetation spectral features can detect chlorophyll concentrations. Two key spectral features evident in the first derivative (FD) of reflectance constitute the two main peaks: one located around 685-705 nm and the other near 710-725 nm. We propose that the area between peaks (ABP) can be used as a sensitive indicator of changes in the photosynthetic pigments at leaf level and demonstrate it using a high-spectral-resolution dataset of maize leaves collected by Gitelson and coworkers (2005). We find significant high positive correlations (r2 > 0.90) between chlorophyll concentrations and both the ABP and its continuum length feature. Read more here.

Winner of the 2014 Leptoukh Lecture Announcement
The Earth and Space Science Informatics (ESSI) Focus Group is proud to announce that this year's winner of the Leptoukh lecture is Bryan Lawrence from the University of Reading's National Center for Atmospheric Science (NCAS). The title of his talk will be: Trends in Computing for Climate Research, and it will be given at the 2014 AGU Fall Meeting. An excerpt of the abstract:
The grand challenges of climate science will stress our informatics infrastructure severely in the next decade. Our drive for ever greater simulation resolution/complexity/length/repetition, coupled with new remote and in-situ sensing platforms present us with problems in computation, data handling, and information management, to name but three. These problems are compounded by the background trends: Moore's Law is no longer doing us any favours: computing is getting harder to exploit as we have to bite the parallelism bullet, and Kryder's Law (if it ever existed) isn't going to help us store the data volumes we can see ahead. The variety of data, the rate it arrives, and the complexity of the tools we need and use, all strain our ability to cope. The solutions, as ever, will revolve around more and better software, but "more" and "better" will require some attention.
In this talk we discuss how these issues have played out in the context of CMIP5, and might be expected to play out in CMIP6 and successors. Although the CMIPs will provide the thread, we will digress into modelling per se, regional climate modelling (CORDEX), observations from space (Obs4MIPs and friends), climate services (as they might play out in Europe), and the dependency of progress on how we manage people in our institutions. It will be seen that most of the issues we discuss apply to the wider environmental sciences, if not science in general.
China has launched two satellites into orbit -- Yaogan-21 remote sensing satellite and the Tiantuo-2 satellite -- from the Taiyuan Satellite Launch Center, in north China’s Shanxi Province.
The Yaogan-21 will be used for scientific experiments, surveying natural resources and crop yields and helping with disaster relief. The Tiantuo-2 is designed for small satellite experiments.
NASA's Office of Education is accepting new proposals under the Education Opportunities in NASA STEM (EONS) 2014 NASA Research Announcement for the MUREP Institutional Research Opportunity (MIRO) appendix. This effort was previously titled as the NASA University Research Centers Project and has now been consolidated into the MUREP Program within the NASA Office of Education. Through the EONS omnibus solicitation, the opportunity MIRO has been released.
Overall, MIRO awards aim to promote Science, Technology, Engineering, and Math (STEM) literacy and to enhance and sustain the capability of minority serving institutions to perform NASA-related research and education, which directly supports NASA’s four Mission Directorates – Aeronautics Research, Human Exploration and Space Operations, Science, and Space Technology.
Proposals are due November 12, 2014.
For more information regarding the MIRO Solicitation, please visit the NASA EONS page in NSPIRES http://nspires.nasaprs.com/external/.
The latest index of airborne geophysical surveys from across Australia has been released. This edition includes details of all available open-file surveys completed to date by the Australian, State and Territory governments, as well as the private sector.
This type of data is used to generate three dimensional models of the sub-surface geology, which can then be used to support decision making related to the development of resources, management of the environment and the wellbeing of communities in the survey areas.
The Index of Airborne Geophysical Surveys (14th Edition) now includes details on surveys that have acquired more than 34.9 million line kilometres of mainly magnetic intensity and gamma-ray spectrometric data. It also includes details on surveys where land elevation data are derived from GPS recordings made during airborne magnetic and gamma-ray spectrometric surveys, with electromagnetic data also available for some areas.
Geophysical survey data measures variations in the Earth's physical properties caused by changes in the physical properties of rocks in the sub-surface, such as magnetisation, natural radioactivity and electrical conductivity.
Since 1999, Geoscience Australia and State and Territory Geological Surveys have contracted airborne geophysical companies to undertake surveys, either separately or as part of joint projects. Geoscience Australia's predecessors the Australian Geological Survey Organisation (AGSO) and the Bureau of Mineral Resources (BMR) used their own aircraft between 1951 and 1999. Airborne survey index information was first published in 1977 by the BMR.
The open-file airborne geophysical data included in the National Airborne Geophysical Database are available free via the Geophysical Archive Data Delivery System on the Australian Government Geoscience Portal. This includes all open-file geophysical surveys completed prior to this latest edition.

Papanikos, President, ATINER (email@example.com).
The Athens Institute for Education and Research (ATINER) was established in 1995 as an independent world association of Academics and Researchers. Its mission is to act as a forum where Academics and Researchers from all over the world can meet in Athens, in order to exchange ideas on their research, and to discuss future developments in their disciplines.
The organizing and hosting of International Conferences and Symposiums, the carrying out of Research, and the production of Publications are the basic activities of ATINER. Since 1995, ATINER has organized more than 350 International Conferences and other events, and has published close to 150 books. In 2012, the Association launched a series of conference paper publications (click here), and at the beginning of 2014, it introduced its own series of Journals.
Academically, the Association is organized into six Research Divisions and thirty Research Units. Each Research Unit organizes at least an Annual International Conference, and may also undertake various small and large research projects.
Academics and Researchers are more than welcome to become members and to contribute to ATINER's objectives. If you would like to become a member, please download the relevant form (membership form). For more information on how to become a member, please send an email to: firstname.lastname@example.org.
