Fieldservers and Sensor Service Grid as Real-time Monitoring Infrastructure for Ubiquitous Sensor Networks
The fieldserver is an Internet based observation robot that can provide an outdoor solution for monitoring environmental parameters in real-time. The data from its sensors can be collected to a central server infrastructure and published on the Internet. The information from the sensor network will contribute to monitoring and modeling on various environmental issues in Asia, including agriculture, food, pollution, disaster, climate change etc. An initiative called Sensor Asia is developing an infrastructure called Sensor Service Grid (SSG), which integrates fieldservers and Web GIS to realize easy and low cost installation and operation of ubiquitous field sensor networks
Modular System for Shelves and Coasts (MOSSCO v1.0) - a flexible and multi-component framework for coupled coastal ocean ecosystem modelling
Shelf and coastal sea processes extend from the atmosphere through the water
column and into the sea bed. These processes are driven by physical, chemical,
and biological interactions at local scales, and they are influenced by
transport and cross strong spatial gradients. The linkages between domains and
many different processes are not adequately described in current model systems.
Their limited integration level in part reflects lacking modularity and
flexibility; this shortcoming hinders the exchange of data and model components
and has historically imposed supremacy of specific physical driver models. We
here present the Modular System for Shelves and Coasts (MOSSCO,
http://www.mossco.de), a novel domain and process coupling system
tailored---but not limited--- to the coupling challenges of and applications in
the coastal ocean. MOSSCO builds on the existing coupling technology Earth
System Modeling Framework and on the Framework for Aquatic Biogeochemical
Models, thereby creating a unique level of modularity in both domain and
process coupling; the new framework adds rich metadata, flexible scheduling,
configurations that allow several tens of models to be coupled, and tested
setups for coastal coupled applications. That way, MOSSCO addresses the
technology needs of a growing marine coastal Earth System community that
encompasses very different disciplines, numerical tools, and research
questions.Comment: 30 pages, 6 figures, submitted to Geoscientific Model Development

Cities and climate change: Strategic options for philanthropic support
Now, more than ever, cities are at the front lines of U.S. climate action. As national action stalls,
there is still a daunting amount to be done in reducing human-generated climate emissions.
Fortunately, this report comes in the wake of a groundswell of initiatives to engage on climate
change by cities, countries, and states across the U.S. Several important and thorough reports
on the types of mitigation actions cities can take have recently been released. We already have
examples of cities taking significant leadership roles in reducing their own climate emissions,
from New York and Boston to Austin, Boulder, and Los Angeles - yet U.S. climate emissions
continue to rise, and cities have an outsized role to play.
The purpose of this project is to review current U.S. city climate activities in order to identify
areas where additional investment by foundations could help accelerate city action to reduce
urban greenhouse gas emissions. The focus of the inquiry is on aggressive actions cities can take
that significantly increase their “level of ambition” to achieve emissions reductions on an
accelerated timetable. City strategies on climate adaptation are not encompassed in this
project. [TRUNCATED
