“…This is due to the limited number of in situ stations with traditionally long periods of data records for meaningful exploration of PW, unlike other regions in the mid-latitude of the Northern Hemisphere. Preliminary results of the spatial variability of PW over Poland on the basis of GNSS data were presented in 2021 [61], supported with a geostatistical modeling approach for spatial interpolation. In our work, we have used high temporal and spatial resolution meteorological data, provided by the WRF model, to present the long-term gridded climatology of PW over Poland.…”

In this work, the high-resolution spatial and temporal variability of precipitable water (PW) over Poland is presented. PW is one of the key parameters of the atmosphere taken into account in thermodynamic and radiation models. The daily PW values from years 2001–2010, calculated with the use of the WRF model, were compared with PW from soundings. The WRF modeled PW is in close agreement with measurements for the whole column of the troposphere and for individual levels: below 1.5 km, 1.5–3 km, 3–6 km and 6–10 km. The best agreement is observed in the lower part of the troposphere, especially for winter months. At the levels of 1.5 km to 10 km, the WRF model overestimates the PW values throughout the year, whereas up to 1.5 km PW is underestimated. The study shows an increasing trend of PW annual values between 1983 and 2010, but the trend is statistically insignificant. A significant positive trend with a high Sen’s slope is observed for the summer season up to 3 km in the troposphere, along with a significant negative tendency for spring. The trends in PW over Poland and Central Europe identified in this study contribute to the ongoing discussion on the observed climate changes.

“…Studies of central and eastern Europe, based on precipitable water (PW) extracted from GNSS data, have shown that, in recent years, the magnitude of this parameter varies from year to year and from season to season. The results of the studies show differences in the magnitude of precipitation water directly related to geographical location and seasonal variations and trends [26]. Due to ongoing climate change on a global as well as local scale, a further increase in PW values over the CEE region directly linked to a systematic increase in temperature is expected.…”

“…Influences of the Atlantic Ocean and the Eurasian continent clash over Europe, which means that the western part of Europe is predominantly influenced by the Atlantic, while the eastern part is mainly influenced by the continent's interior (Eurasia). Central and eastern Europe are located in the zone that mixes both influences (the climate varieties are maritime and continental) [26]; hence, the atmospheric conditions prevailing in this part of the continent are extremely complicated and difficult to forecast. The contribution of air masses from the Arctic and Atlantic oceans to meteorological and, in the longer term, climatic conditions is significant, as described in [27,28].…”

The solar power industry is a rapidly growing sector of renewable energy, and it is crucial that the available energy is accurately forecast. Using numerical weather prediction models, we can forecast the global horizontal irradiance on which the amount of energy produced by photovoltaic systems depends. This study presents the forecast effects for one of the most challenging weather conditions in modelling, occurring in central and eastern Europe. The dates of the synoptic situations were selected from 2021 and 2022. Simulations were carried out for 18 days with a cold front and, in order to verify the model configuration, for 2 days with a warm front, 2 days with an occlusion front and 2 days with a high pressure situation. Overall, 24 forecasts were made for each of the three parameterizations of the Weather Research and Forecasting model. The data were compared with the values measured in situ at the station performing the actinometric measurements belonging to Germany’s National Meteorological Service. This paper presents the spatial distribution of the global horizontal irradiance parameters for several terms to explain the differences between the results of the different simulations.

Integration of Distributed Dense Polish GNSS Data for Monitoring the Low Deformation Rates of Earth’s Crust

This research concerns the possibility of monitoring low deformation rates in tectonically stable regions using GPS/GNSS observations. The study was conducted in an area of Poland located in Central and Eastern Europe, where horizontal stress resulting from plate boundary forces in the N–S or NNE–SSW direction has been observed. This stress can translate into deformation of the Earth’s surface. The problem, however, is that it corresponds to strain rate magnitudes of much lower than 10 × 10−9 per year. This is not much higher than the figure determined using current GNSS observation capabilities. In this study, long-term observations from several GNSS networks were used. The result was a very dense but irregular velocity field. By carefully analyzing and filtering the data, it was possible to eliminate the impact of various errors, creating a more consistent velocity field. This article presents a final GNSS strain rate model for Poland and determines the impacts of the analysis methods on its variation. Regardless of the filtering method adopted, dominant compression rates in the N-S direction are evident. Moreover, this result is consistent despite the use of varying velocity. This shows that even in tectonically stable regions, strain rates can be monitored at 10−9 per year (below 3 × 10−9/year).
