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 using the Linear Recurrence Formula (LRF). The analysis... 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 Moving...

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, ocean water precipitates, and a variety of... 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 episodes to capture duration-driven drought... 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... More

Abstract: Climate change and technological advancement are driving a paradigm shift in the atmospheric and hydrometeorological sciences. This transformation is reflected in the complex interactions between ocean and atmospheric dynamics, the role of climate phenomena such as El Niño and La Niña, and the consequent effects on global water resources. This editorial argues that the critical task for the coming decade is to advance from hazard-focused... More
