Abstract: Singular Spectrum Analysis (SSA) was applied to daily time series of carbon monoxide (CO) and ozone (O₃) observed between 2000 and 2018 in Campo Grande, MS, Brazil, to identify seasonal patterns, long-term variability, and evaluating the predictive capacity of the technique. The methodology involved the decomposition of the series into structural components and subsequent prediction... More

Abstract: Rainfall prediction is crucial for agricultural planning and water resource management, as Bangladesh’s agriculture heavily depends on rainfed irrigation. Existing forecasting models are complex and costly, both budgetarily and computationally. As a result, our study evaluates the comparative performance of forecasting models, comprising two traditional time series models (Exponential Smoothing (ES) and Seasonal Autoregressive Integrated...

Abstract: Atmospheric aerosols can have wide-ranging effects on the Earth’s atmosphere, hydrosphere, and biosphere. To help improve our understanding of these effects, we have conducted spectral reflectance and transmission properties of a suite of anthropogenic and natural aerosols across a wide wavelength range (0.35–25 microns). Our sample suite included rock and mineral dusts, sulfates and nitrates,... More

Abstract: This study analyses the persistence and frequency of multi-day dry and wet rainfall episodes over Côte d’Ivoire, which are quantified using CPC observations (1979–2022) and a 14-member Coordinated Regional Climate Downscaling Experiment (CORDEX)-Africa ensemble under RCP4.5 and RCP8.5. Rather than focusing solely on total rainfall, we quantify rainfall by duration and frequency of dry spells and wet... More

Abstract: Increased non-methane hydrocarbons (NMHCs) emissions brought on by urbanisation, industrialisation, and a warming planet have significantly modulated regional atmospheric photochemistry, ground-level ozone formation, oxidant levels, and secondary organic aerosol production. India, being a country with fast-paced changes with excessive and variable emissions like in the Indo-Gangetic Plains, a comprehensive understanding of the temporal and spatial... More
