The general trend of modern ecological geophysics is changing priorities towards rapid assessment, management and prediction of ecological and engineering soil stability as well as developing brand new geophysical technologies. The article describes researches conducted by using multi-canal geophysical logger MGR-01 (developed by IMCES SB RAS), which allows to measure flux density of very low-frequency electromagnetic radiation. It is shown that natural pulsed electromagnetic fields of the earthen lithosphere can be a source of new information on Earth’s crust and processes in it, including earthquakes. The device is intended for logging electromagnetic processes in Earth’s crust, geophysical exploration, finding structural and lithological inhomogeneities, monitoring the geodynamic movement of Earth’s crust, express assessment of seismic hazards. The data is gathered automatically from observation point network in Siberia
The article describes a software system intended for supporting scientific researches of the atmosphere during the processing of data gathered by multi-level ultrasonic complexes for automated monitoring of meteorological and turbulent parameters in the ground layer of the atmosphere. The system allows to process files containing data sets of temperature instantaneous values, three orthogonal components of wind speed, humidity and pressure. The processing task execution is done in multiple stages. During the first stage, the system executes researcher’s query for meteorological parameters. At the second stage, the system computes series of standard statistical meteorological field properties, such as averages, dispersion, standard deviation, asymmetry coefficients, excess, correlation etc. The third stage is necessary to prepare for computing the parameters of atmospheric turbulence. The computation results are displayed to user and stored at hard drive.
The article describes an iterative parallel phase grouping algorithm for temperature field classification. The algorithm is based on modified method of structure forming by using analytic signal. The developed method allows to solve tasks of climate classification as well as climatic zoning for any time or spatial scale. When used to surface temperature measurement series, the developed algorithm allows to find climatic structures with correlated changes of temperature field, to make conclusion on climate uniformity in a given area and to overview climate changes over time by analyzing offset in type groups. The information on climate type groups specific for selected geographical areas is expanded by genetic scheme of class distribution depending on change in mutual correlation level between ground temperature monthly average.
Basing upon example of Wolf number series synchronous analysis and temperature values from 818 meteorological stations in the Northern hemisphere (1955-2010) it is shown that, for studied series, the components that differ by distinctive features matching and mismatching display extreme properties. The histograms of the primary temperature series coincide with histograms of their components except for the range of ± 3°С. Second initial moments of Wolf numbers’ components match climate geography and end up in two zones with width and difference in-between equal to about a third of possible change amount. Correlating synchronization features of geosphere processes initiated by external influence, with the use of physical-geographical hierarchy, allows to solve the classification task for temperature field; i.e. it allows to decompose initial sets into subsets containing strongly connected components. There were no discrepancies with known ideas about climate processes.
This article justifies the usage of natural pulsed electromagnetic Earth’s noises logging method for mapping anomalies of strain-stress state of Earth’s crust. The methods and technologies for gathering, processing and systematization of data gathered by ground multi-channel geophysical loggers for monitoring geomagnetic situation have been experimentally tested, and software had been developed. The data was consolidated in a network storage and can be accessed without using any specialized client software. The article proposes ways to distinguish global and regional small-scale time-space variations of Earth’s natural electromagnetic field. For research purposes, the software provides a way to export data for any given period of time for any loggers and displays measurement data charts for selected set of stations.
This article presents the results of developing a software for surface meteorological observation network storage. Multithreading was used to simulate a distributed cluster of information-computational resources during the software testing. This technology is used to create concurrently executing threads and is supported by practically every operating system. The architecture of the meteorological data network storage was designed and includes the following modules: coordinating module (monitors and displays computing nodes), database manager module (distributes meteorological data and executes user queries), client module (allows accessing the data), terminal modules (allows uploading new data), storage and processing modules (nodes for distributed data storage). The system was designed using platformindependent development tools (Java technologies), underwent simulation testing to improve the module interaction, ensure system performance, stability and reliability during processing large volumes of meteorological data.
This paper reviews the concept of designing an open, horizontally scalable distributed information and computing environment, presented in the form of decentralized resource architecture (including computing nodes, storage nodes, communication channels) with decentralized computations and data management. The distributed infrastructure divided into two main components, the computational cluster and the storage cluster. Management of the cluster assigned to specialized frameworks – the infrastructure manager, network manager, computing manager, storage manager, authorization manager, web manager, upload manager. This paper shows the results of a practical study of the processed meteorological parameters obtained with standard ultrasonic weather station on the developed information-computational environment.
