National Conference on Science of Climate Change and Earth’s Sustainability: Issues and Challenges ‘A Scientist-People Partnership’ 12-14 September, 2011, Lucknow The core concept of energy informatics is energy plus computer science aided information with a view to reduce the energy consumption in a particular system. This means analyzing, designing and implementing information systems to increase energy efficiency. The energy informatics consists of collection and analysis of energy data sets, optimization of energy distribution networks and optimization of energy consumption systems with computer algorithms and simulations. It incorporates the framework for supply and demand sides, flow networks, sensor network, sensitized object and information system with strong coupling between computing components and non-computing processes in physical environment. The work of computer supported information system is that it ties together the elements to provide a complete solution, integrates supply and demand for a comprehensive solution, provides interfaces for suppliers and consumers, automates aspects of the flow network and incorporates sense and act mechanisms. Computing systems having strong coupling with the physical environment are referred to as the Cyber-Physical Systems (CPSs). These systems usually monitor, coordinate, and control non-computing processes. Recent advances in the sensor technologies and embedded computing systems have seen a surge of CPSs being investigated. Many developed and developing countries are trying to use energy informatics in their traffic management, building automation, energy management programmes and fleet management among others. With the increasing cost of electricity and other conventional energy supplies (oil, coal and natural gas), the emphasis is being laid on the eco-friendly sources of energy like solar, wind, biomass and others and also on enhancing the energy efficiency in various sectors of energy use to combat global warming and climate change. Energy informatics has a great role to play for the energy systems in the near future. EFFECT OF GLOBAL WARMING ON CLIMATE CHANGE OF THE EARTH Avadhesh Kumar Yadav , C.R. Gautam * and Arbind Kumar Singh Department of Physics, University of Lucknow, Lucknow 226 007 * email: gautam_ceramic@yahoo.com Global warming is a very crucial problem for whole environment because of increase in average temperature of troposphere and stratosphere. The depletion of ozone layer, release of carbon dioxide (CO 2 ), carbon monoxide (CO), methane (CH 4 ) and other heat - trapping gases from smokestacks, construction, industries, transport, consumption and burning forests has been raising temperature of atmosphere day by 76
National Conference on Science of Climate Change and Earth’s Sustainability: Issues and Challenges ‘A Scientist-People Partnership’ 12-14 September, 2011, Lucknow day. Nowadays, there is a serious problem of global warming and continuously affecting to the earth's climate. Therefore, earth’s climate is suddenly changing through a natural cycle. Climate change is a long term change in the statistical distribution of environment and weather. These changes may be attributed to directly or indirectly to human activity that alters the composition of the global atmosphere. In addition to natural climate variability observed over long periods. Climate change reflects variation in the energy balance of the climate system. The relative balance between incoming solar radiation and outgoing infrared radiation from the earth attribute to radiative forcing. Efforts have been made for curing such a big problem by using unlimited renewable energy sources. EFFECT OF GEOMAGNETIC ACTIVITY ON IONOSPHERIC RANGE-ERROR IN GPS SIGNAL DURING LOW SOLAR-ACTIVITY PERIOD AT LOW LATITUDE STATION Sanjay Kumar and A.K. Singh Atmospheric Research Lab, Department of Physics, Banaras Hindu University Varanasi-221005 Present paper describes analysis of GPS-data recorded at Varanasi, a station near the Equatorial Ionization Anomaly (EIA) to study the effect of magnetic activity on ionospheric range error. The variability in GPS range error due to presence of Total Electron Content (TEC) of the ionosphere during five most quiet and most disturbed days of each month of year 2008 is carried out. The result shows GPS ranging error is found to be more during disturbed days compared to quiet days, showing maximum in equinox, minimum in summer and winter season. The variability of positioning error during the period of two geomagnetic storms, March 2008 and October 2008 is also studied. 77
