This study employs an inverse grey-box (IGB) modeling approach, which combines measured data and the physics of systems to predict performance shallow underground thermal energy storage (UTES) with top side insulation. A simplified IGB model UTES was developed using network analysis. Experimental studies were conducted for vertical horizontal configurations. Detailed models representing field experiments TRNSYS simulation tool calibrated from experimental setup. The 4 Resistance 2 Capacitance (4R2C) trained tested in MATLAB model. In comparing UTES, prediction outlet water temperature showed good agreement, root mean square error (RMSE) coefficient variation RMSE (CVRMSE) values 0.94 °C 3.16% vertical, 0.99 2.97% also aligned well data, showing CVRMSE 7.91% 3.17% systems, respectively. Sensitivity analysis revealed that improves longer training durations closer testing times periods.

Abstract The fundamental scientific and engineering knowledge concerning the solar power curve, which maps irradiance other auxiliary meteorological variables to photovoltaic output power, has been gathered put forward in preceding tutorial review. Despite many pages of that review, it was incomplete sense did not elaborate on applications this very important tool energy meteorology. Indeed, curves are ubiquitously needed a broad spectrum forecasting resource assessment tasks. Hence, review should continue from where left off present examples usage curves. In nutshell, together with one, elucidate how surface shortwave radiation data, be they ground-based, satellite-retrieved, or model-output, bridged various system operations via

Aerosols play a crucial role in the surface radiative budget by absorbing and scattering both shortwave longwave radiation. While most aerosol types exhibit relatively minor forcing when compared to their counterparts, dust aerosols stand out for substantial forcing. In this study, radiometers, sun photometer, microwave radiometer parameterization scheme clear-sky radiation estimation were integrated investigate properties of aerosols. During an event Xianghe, North China Plain, from 25 April 27 2018, composition (anthropogenic dust) optical depth (AOD, ranging 0.3 1.5) changed considerably.

Forests are one of the most important sources negative oxygen ions (NAIs). NAIs have been recognized as beneficial for both physical and mental well–being, higher concentrations associated with improved health. However, environmental factors that predominantly influence NAI concentration their relationship remain uncertain. This study aims to investigate dominant impact on by observing various in two different environments (natural forest urban forest) Beijing region over a one–year period. Through our investigation, we aimed identify key factor well other influential variables affecting concentration. Our analysis encompassed examination dynamic changes multiple time scales, revealing uniform trends types. Notably, natural forests consistently demonstrated across these attributable greater vegetation density stability microenvironment. By utilizing regression, correlation analysis, structural equation determined relative humidity (RH) has significant effect RH displayed similar patterns scales. When considering hourly average daily variation, lowest values were observed at noon, followed an increase persisted throughout night. Seasonal variation showed peaked summer, autumn. In terms annual summer exhibited more days high RH, which can be attributed increased rainfall during season. Rainy weather was found contribute levels. Furthermore, findings revealed scale, occurred frequently under conditions air temperature low wind speed. quality index only minor forest, while net radiation no RH.

The National Standard of China has recommended the typical meteorological year (TMY) method for assessing solar energy resources. Compared with widely adopted multi-year averaging (MYA) methods, TMY can consider year-to-year variations weather conditions and characterize radiation under climatological conditions. However, there are very few TMY-based assessments on scale China. On national scale, difference between MYA requirement data record length, impacts selection variables assessment still unclear. This study aims to fill these gaps by mainland China’s resources using Meteorological Forcing Dataset. results show that length could significantly influence annual total estimation when is shorter than 30 years. Whereas, becomes stable greater or equal years, suggesting a thirty-year preferred. methods exhibited primarily in places modest low abundance radiation. nearly independent examined lengths, hinting at role regional-specific characteristics. differ more pronounced seasonal stability grade.
