This paper presents a brief description of the ground-based installation for the study of cosmic rays "CARPET". Today there is a network of such installations located in different parts of the world. For ground-based installations, meteorological effects must be considered as they affect the data. This paper shows a technique for eliminating barometric and temperature dependences based on data for 2019–2020.

This paper describes a seismic data set acquired by network of broadband sensors in Poland and technical issues related to data acquisition. We describe a new azimuth-transfer device for precise sensor orientation and apply methods for data-based orientation checking. We analyze the seismic noise level and discuss effect of geology at sites on character of seismic data and noise. We show data examples and describe methods of seismic data interpretation for studies of lithospheric structure.

The LOPS measure the magnetic field with high spatial coverage. Although there are no magnetic cleanliness to the satellites, triple sensors configuration enables removal of interferences from the satellites. Results show they are able to capture the Earth’s internal as well as the external fields from the magnetosphere-ionosphere current system. This study implies that large number of small low-cost satellites without magnetic cleanliness would be
the future for the space magnetic exploration.

In this paper, we have produced definitive data from Indonesian Geomagnetic Observatories to create a standardized high-quality set of measurements for scientific exploitation. We explain the steps taken to improve upon the data collections and processing protocols that previously existed and suggested improvements to enhance the quality of the magnetic time-series. The data can fill the gap in the Pacific region and provide input into geomagnetic modeling and secular variation studies.

This paper is dedicated to description of universal, easy to modify and affordable rock slope monitoring system. By such a system, we are able to monitor environmental variables, rock mass 3 m surface zone temperature and temporal dynamic of selected joints. So far, we are observed differences between three monitored sites, however, to further data analyses longer time series are needed. We hope, our work encourage scientific community to increase knowledge in this interesting field.

This paper describes the development of a new multifunctional 4-dimensional (4D) high-density electrical instrument based on remote wireless communication technology, for use in shallow geophysical prospecting. We did lots of tests. Our design successfully addresses a number of shortcomings of such instruments currently available on the market, including bulkiness, weight, limitations in data acquisition accuracy, and difficulty of connecting to the Internet for remote monitoring.

Based on the intercomparison of a photoacoustic and a cavity attenuation phase shift instruments, this manuscript has corrected and calibrated the data of recent field measurement. It showed good agreement and closure correlation in the optical properties measured from different optical methods, and the scattering coefficient part plays a crucial role as the bridge in constructing correlation of both instruments.
