Summary: This study presents a new method to estimate aerosol optical depth at a specific location using direct normal irradiance measurements and radiative transfer models. Both SMARTS and SOLIS models show good performance in estimating DNI under clear-sky conditions. By iterating the models with 1-minute DNI measurements, accurate AOD values can be derived, despite challenges in selecting clear line of sight periods.

Summary: This paper presents a mobile sensor system that uses a team of unmanned aerial vehicles (UAVs) to localize and characterize the shadow of mobile clouds for detecting and estimating low direct normal irradiance (DNI) areas caused by clouds shadows. The simulations show that the algorithm used in this system achieves a similar degree of precision in estimating the shape of the cloud shadow, but with a much faster computational time compared to other algorithms described in literature.

Summary: Continuous measurements of aerosol optical depth (AOD), water vapor, and ozone concentrations were conducted in a semi-arid urban area in western India. The results showed significant seasonal variations in AOD and ozone concentrations, with the post-monsoon season being influenced by both anthropogenic and natural sources. The dominant source of aerosols was wind-blown and transported dust, particularly during the pre-monsoon and monsoon seasons.

Summary: A refined classification of aerosol types in China was achieved by improving the resolution and accuracy of aerosol optical depth (AOD). The accuracy of AOD acquired from MERRA2 and CAMS was validated by comparing with AERONET. AOD was simulated with high resolution and accuracy using the ERT, AdaBoost, and GBDT models, and aerosol types were identified based on AE from MODIS and calibrated AOD. The results showed that CAMS overestimates AOD (21.4%) and MERRA2 underestimates AOD (-17.3%). The ERT model performed the best, with an R2 of 0.825 and RMSE of 0.174. Biomass burning/urban-industrial aerosols dominated China, particularly in southern, eastern, and central regions during spring and summer.

Summary: This study used the Informer model to predict GHI, considering AOD, meteorological parameters, and historical GHI data as input variables. The results showed that the models considering AOD had lower prediction errors, and the difference was more significant when the predicted day had a larger AOD. By adding Planck's average AOD as a feature input, the accuracy of the model was improved regardless of the AOD size on the prediction day.

Summary: The all-sky Aerosol Direct Radiative Effect (ADRE) varies considerably among global climate models (GCMs) due to differences in aerosol and atmospheric states and the sensitivity of ADRE to aerosol-related radiative processes. This study uses a regression method to analyze the inter-model spread of ADRE in the Sixth Coupled Model Intercomparison Projects (CMIP6), finding that differences in state variables and radiative sensitivity explain a significant portion of the global ADRE anomaly. The primary factors driving the ADRE anomaly vary among models, leading to spatial variance in global ADRE spread.

Summary: This study evaluates the relationship between Average Photon Energy (APE) and spectral Direct Normal Irradiance (DNI) by analyzing a dataset collected in Jaen, Spain. The findings suggest that APE may uniquely characterize the DNI spectrum distribution only within the 450-900nm waveband, with the coefficient of variation (CV) staying below 3.5% in this range.

Summary: Accurate modeling of solar radiation under cloudless situations is crucial for the development of renewable energy resources. Existing clear-sky solar radiation models often perform inconsistently due to deficiencies in simulating aerosol extinction. A new analytical parameterization of aerosol transmittance has been introduced to address these issues and has shown consistent performance under different aerosol conditions worldwide.

Summary: Interpolation is a crucial process in solar resource assessment, and it plays a significant role in connecting consecutive components in the modeling chain. However, traditional interpolation methods often assume that the interpolating function must pass through interpolation points, which is not suitable for averaged datasets or variables that require consistency across the interpolation. To address this issue, the author introduces a mean-preserving splines method that can effectively interpolate one-dimensional data while conserving the interpolated field. This method utilizes second-order polynomial splines to minimize fluctuations in the interpolated field and restricts the interpolation results within user-provided limits. It also handles periodic boundary conditions and non-uniform averaging grids. The validity and performance of the method are demonstrated through relevant case examples in the solar resource assessment field.

Summary: This research tests the performance of CM-SAF SRI and NSRDB-S satellite-based spectral irradiance products at seven ground stations, against benchmark data and models. The results show that CM-SAF SRI generally outperforms First Solar and no spectral effects benchmarks, while NSRDB-S has lower accuracy in predicting long-term spectral derate factors compared to instantaneous SMMs. Spectra comparisons reveal systematic differences between NSRDB-S and benchmark spectra, likely due to differences in aerosol treatment.

Summary: The spectral distribution of solar irradiance is crucial for the power production of PV modules. However, current spectroradiometers have limitations in accurately measuring the full spectrum of some PV technologies. This study proposes a new methodology using the SMARTS spectral code to extend the spectral range and resolution of measured irradiance spectra, providing satisfactory results in both clear and hazy sky conditions. This approach serves as a foundation for obtaining the instantaneous spectral irradiance incident on PV module arrays and evaluating the impact of atmospheric constituents on surface irradiance.

Summary: As the global population grows, the demand for food, energy, and water will increase significantly. However, limited land availability and competition for solar resources pose challenges to resource generation technologies. In the United States, both agriculture and solar energy production have adopted densification schemes to improve yields and energy output per unit of land. This research proposes an Agrivoltaic food and energy coproduction architecture that optimizes power generation while maintaining crop productivity by implementing ideal anti-tracking during critical growth periods. This technology offers a viable pathway for widespread solar implementation throughout the contiguous United States.
