This paper presents a novel method for measuring the data for evaporation estimation as the key ingredient for the final decision of the reclamation form in the area of the Most Basin. The area has been intensively mined for many decades, resulting in significant landscape devastation, loss of natural habitats, and negative environmental impact. Currently, it is assumed that by 2050, three large-scale reclamation projects will be implemented in the area and it is necessary to decide which form of reclamation to choose. Whether to build lakes according to the currently valid rehabilitation and reclamation plan or to leave the area of the quarries in succession with the support of spontaneous inflow of water up to a naturally sustainable water level. Whether the first or second option is approved, or a combination of both, the prediction of evaporation from the free water surface will always be of great importance. To deal with this goal, the available meteorological data must be combined with a suitable calculation method. In our work, we suggest utilizing a measuring network of meteorological devices that describe the character of the weather in a given area of interest in a long-term time series. Together with the state-of-the-art calibration of models for calculating evaporation, the measurement network helps to provide more accurate evaporation data for a given area. Based on the analysis of research results, it will be possible to choose a specific right decision and thus contribute to the long-term sustainability of these reclamations.

W pracy omówiono zagadnienia pomiarów natężenia pola elektrostatycznego pochodzenia atmosferycznego oraz monitorowania jego zmian na dużych obszarach w trudnych warunkach polowych, m.in. podczas burz. Zaprezentowano model sieci pomiarowej z cyfrowym przesyłem informacji, wykorzystującej zdalne mierniki pola elektrycznego typu field mill, wyposażone w mikroprocesorowe przystawki z interfejsem RS485 i obsługą protokołu ModBus. Przedstawiono wyniki długotrwałych pomiarów natężenia pola elektrycznego pochodzenia atmosferycznego oraz jego zaburzenia obserwowane w czasie trwania burzy.

The paper discusses problems related to measurements and monitoring of electrostatic filed strength as well as its variations over large areas in harsh environmental conditions e.g. during thunderstorms. A model of measuring network with digital data transmission is presented which makes use of remote electrostatic field mill meters fitted with microprocessor attachments, RS485 interfaces and ModBus data exchange protocol. Results of long-term monitoring of atmospheric electric field strength as well as its disturbances during a thunderstorm are presented.
