geographic information and analysis provide a wide range of data and techniques to monitor and manage natural resources. as an important case, in arid and semi-arid areas, water management is critical for both local governance and citizens. as a result, the estimation of water potential brought by snowmelt runoff and rainfalls seems to be very useful and important for these areas. hydrological ...

one of the most main head in governments is to achieve the energy for their countries. as the fossil sources are at their ends and also they cause greenhouse emission and environment pollution, shifting to renewable sources of energy is an indispensable alternative for most countries. the sun is the most important renewable energy source. to assessment reachable solar radiation in mashhad from ...

abstract long-term historical weather data are needed to conduct crop simulation analysis. simulated climatic data may be used when long series of historic data are not available or convenient or when future data are needed. the aim of this study was to generate daily weather values for maximum and minimum air temperatures. a number of weather generators are compared here. data from ten station...

Effective exploitation of meteorological archives has long been impeded by an inability to rapidly identify relevant data, and by the difficulties of managing the large volume of data involved. We present a new approach to archiving meteorological data that addresses these problems. Our approach is implemented in MetVUW Workbench, a case-based system for intelligent retrieval and display of his...

Large repositories of historical data about the natural world present novel opportunities to assist decision makers and problem solvers. Past cases or scenarios that are similar to a problem of current interest can often provide valuable insights or suggest solutions to the problem. We are constructing a case retrieval system that is intended to give meteorologists fast access to relevant past ...

The remote sensing of atmospheric trace gases investigates dynamic, microphysical and chemical processes in the Earth’s atmosphere, with the goal to understand, quantify and predict its natural variability and long-term changes. Accurate measurements of atmospheric trace gases from various observational platforms (ground-based stations, air craft, balloons, satellites) provide the data that are...

Large archives of historical meteorological data offer novel opportunities for weather forecasting and meteorological research. However, effective exploitation of such an archive is impeded by the logistics of managing large volumes of data and the difficulty of identifying relevant data. MetVUW Workbench is a case retriever that allows meteorologists to identify relevant past weather situation...

Meteorological data mining is a form of data mining concerned with finding hidden patterns inside largely available meteorological data, so that the information retrieved can be transformed into usable knowledge. Weather is one of the meteorological data that is rich by important knowledge. In this paper we try to extract useful knowledge from weather daily historical data collected locally at ...
