High aerosol levels pose severe air pollution and climate change challenges in Iran. Although regional optical depth (AOD) trends have been analyzed during the dusty season over Iran, specific factors that are driving spatio-temporal variations winter AOD influence of meteorological dynamics on remain unclear. This study analyzes long-term Iran period 2000–2020 using updated Modern-Era Retrospe...

[1] Sub-seasonal variability including equatorial waves significantly influence the dehydration and transport processes in the tropical tropopause layer (TTL). This study investigates the wave activity in the TTL in 7 reanalysis data sets (RAs; NCEP1, NCEP2, ERA40, ERA-Interim, JRA25, MERRA, and CFSR) and 4 chemistry climate models (CCMs; CCSRNIES, CMAM, MRI, and WACCM) using the zonal wave num...

Accurate estimation of the satellite-based global terrestrial latent heat flux (LE) at high spatial and temporal scales remains a major challenge. In this study, we introduce a Bayesian model averaging (BMA) method to improve satellite-based global terrestrial LE estimation by merging five process-based algorithms. These are the Moderate Resolution Imaging Spectroradiometer (MODIS) LE product a...

Abstract. The planetary boundary layer (PBL) governs the vertical transport of mass, momentum, and moisture between surface free atmosphere, thus determination PBL height (BLH) is recognized as crucial for air quality, weather, climate analysis. Although reanalysis products can provide important insight into global view BLH in a seamless way, observed situ on scale remains poorly understood due...
