Black carbon (BC) is one of the main factors in global climate change and human health. Based on reanalysis data from Modern-Era Retrospective Analysis for Research Applications Version 2 (MERRA-2), historical trends variation BC affecting this were investigated core city Central Plains Economic Zone China-Zhengzhou. correlation analysis with ground measurements concentration, it was determined...

The Satellite Application Facility on Climate Monitoring (CM-SAF) Spectral Resolved Irradiance (SRI) and National Renewable Energy Laboratory Solar Radiation Database Demand (NSRDB-S) satellite-based spectral irradiance products are tested here against benchmark data models at seven ground stations: one in Spain for CM-SAF SRI six North America NSRDB-S. Benchmarks include WISER spectroradiomete...

Abstract. Stratospheric circulation is a critical part of the Arctic ozone cycle. Sudden stratospheric warming events (SSWs) manifest strongest alteration dynamics. During SSWs, changes in planetary wave propagation vigorously influence zonal mean wind, temperature, and tracer concentrations stratosphere over high latitudes. In this study, we examine six persistent major SSWs from 2004 to 2020 ...

The spatiotemporal evolution and trends in aerosol optical depth (AOD) over environmentally distinct regions Pakistan are investigated for the period 1980–2018. AOD data this was obtained from Modern-era retrospective analysis research applications, version 2 (MERRA-2) reanalysis atmospheric products, together with Moderate-resolution imaging spectroradiometer (MODIS) retrievals. climatology of...

In this study, the temporal variations of black carbon (BC) were analyzed from November 2019 to September 2021, in Tacna, Peru. Ground measurements obtained with a photoacoustic extinctiometer (PAX BC) and NASA’s MERRA-2 reanalysis data (MERRA-2 used. The seasonal concentrations PAX BC (mean ± standard deviation) as follows: 0.70 0.35, 0.73 0.46, 0.39, 0.85 0.46 µg m−3, for spring, summer, autu...

The aerosol optical property products of Modern-Era Retrospective Analysis for Research and Applications, version 2 (MERRA-2) reanalysis dataset have been extensively investigated on a global or regional scale. However, the understanding MERRA-2 component an extensive temporal spatial scale is inadequate. Recently, derived from observations Polarization Directionality Earth’s Reflectances/Polar...

Abstract. Vertical wind (w) is one of the most important meteorological parameters for understanding a range different atmospheric phenomena. Very few direct measurements w are available so that time must depend on reanalysis products. In present study, assessment among selected reanalyses (ERA-Interim, ERAi; ERA fifth generation, ERA5; Modern-Era Retrospective analysis Research and Application...

Coral reef fish serve as food sources to coastal communities worldwide, yet are vulnerable to mounting anthropogenic pressures like overfishing and climate change. Marine reserve networks have become important tools for mitigating these pressures, and one of the most critical factors in determining their spatial design is the degree of connectivity among different populations of species priorit...
