Reducing Climatology Bias in an Ocean–Atmosphere CGCM with Improved Coupling Physics [PDF]

Journal of Climate, 2005
Abstract The cold tongue in the tropical Pacific extends too far west in most current ocean–atmosphere coupled GCMs (CGCMs). This bias also exists in the relatively high-resolution SINTEX-F CGCM despite its remarkable performance of simulating ENSO variations.

Global and regional emission estimates for HCFC-22 [PDF]

, 2012
HCFC-22 (CHClF[subscript 2], chlorodifluoromethane) is an ozone-depleting substance (ODS) as well as a significant greenhouse gas (GHG). HCFC-22 has been used widely as a refrigerant fluid in cooling and air-conditioning equipment since the 1960s, and it

Tropical Atlantic Mixed Layer Buoyancy Seasonality: Atmospheric and Oceanic Physical Processes Contributions [PDF]

Atmosphere, 2020
This study investigates the physical processes controlling the mixed layer buoyancy using a regional configuration of an ocean general circulation model. Processes are quantified by using a linearized equation of state, a mixed-layer heat, and a salt budget. Model results correctly reproduce the observed seasonal near-surface density tendencies.

Atmospheric and oceanic dust fluxes in the northeastern tropical Atlantic Ocean: how close a coupling? [PDF]

, 2002
. Atmospheric inputs to the ocean of dust originating from Africa are compared with downward dust flux in the oceanic water column. Atmospheric fluxes were estimated using remote-sensing-derived dust optical thickness and parameters from a transport ...

The impact of aerosol hygroscopic growth on the single-scattering albedo and its application on the NO₂ photolysis rate coefficient [PDF]

Atmospheric Chemistry and Physics, 2014
Hygroscopic growth of aerosol particles can significantly affect their single-scattering albedo (ω), and consequently alters the aerosol effect on tropospheric photochemistry.

Estimation of nighttime aerosol optical depths using the ground-based microwave radiometer [PDF]

Atmospheric Measurement Techniques
Aerosol optical depth (AOD) is a crucial parameter for understanding the impact of aerosols on Earth's atmosphere and air quality. Nevertheless, most existing remote sensing techniques rely on the shortwave spectrum, precluding nighttime measurements ...
