Contrasting the direct radiative effect and direct radiative forcing of aerosols [PDF]

open access: yesAtmospheric Chemistry and Physics, 2014
The direct radiative effect (DRE) of aerosols, which is the instantaneous radiative impact of all atmospheric particles on the Earth's energy balance, is sometimes confused with the direct radiative forcing (DRF), which is the change in DRE from pre ...

CECAV-DNN: Collective Ensemble Comparison and Visualization using Deep Neural Networks

open access: yesVisual Informatics, 2020
We propose a deep learning approach to collectively compare two or multiple ensembles, each of which is a collection of simulation outputs. The purpose of collective comparison is to help scientists understand differences between simulation models by ...

WRF Model Parameterization Around the Highland Titicaca Lake

open access: yesEarth and Space Science, 2021
The computational advances and many times the lack of meteorological measurements in some regions of the world impulse the employment of numerical methods for covering this deficiency of data, and the parameterization is a key factor for use and ...

Validation for a tropical belt version of WRF: sensitivity tests on radiation and cumulus convection parameterizations

open access: yesAtmospheric and Oceanic Science Letters, 2019
Version 3.9 of WRF-ARW is run with a tropical belt configuration for a period from 2012 to 2016 in this study. The domain covers the entire tropics between 45°S and 45°N with a spatial resolution of about 45 km.

Modeling the radiative effects of desert dust on weather and regional climate [PDF]

open access: yesAtmospheric Chemistry and Physics, 2013
Mineral dust aerosols exert a significant effect on both solar and terrestrial radiation. By absorbing and scattering, the solar radiation aerosols reduce the amount of energy reaching the surface.

Impacts of aerosol–radiation interaction on meteorological forecasts over northern China by offline coupling of the WRF-Chem-simulated aerosol optical depth into WRF: a case study during a heavy pollution event [PDF]

open access: yesAtmospheric Chemistry and Physics, 2020
To facilitate the future inclusion of aerosol–radiation interactions in the regional operational numerical weather prediction (NWP) system RMAPS-ST (adapted from Weather Research and Forecasting, WRF) at the Institute of Urban Meteorology (IUM), China ...

Orography-Induced Gravity Wave Drag Parameterization in the Global WRF: Implementation and Sensitivity to Shortwave Radiation Schemes

open access: yesAdvances in Meteorology, 2010
This paper describes the implementation of the orographic gravity wave drag (GWDO) processes induced by subgrid-scale orography in the global version of the Weather Research and Forecasting (WRF) model. The sensitivity of the model simulated climatology

Exploring the observational constraints on the simulation of brown carbon [PDF]

open access: yesAtmospheric Chemistry and Physics, 2018
Organic aerosols (OA) that strongly absorb solar radiation in the near-UV are referred to as brown carbon (BrC). The sources, evolution, and optical properties of BrC remain highly uncertain and contribute significantly to uncertainty in the estimate ...

Analysis of the ozone profile specifications in the WRF-ARW model and their impact on the simulation of direct solar radiation [PDF]

open access: yesAtmospheric Chemistry and Physics, 2015
Although ozone is an atmospheric gas with high spatial and temporal variability, mesoscale numerical weather prediction (NWP) models simplify the specification of ozone concentrations used in their shortwave schemes by using a few ozone profiles.

Impact of a New Radiation Scheme on Simulated Climate in the Global–Regional Integrated SysTem Model under Varying Physical Parameterization Schemes

open access: yesAtmosphere
In this study, the radiation scheme BCC-RAD (Beijing Climate Center RADiative transfer model) developed for global climate models is implemented into the Global–Regional Integrated SysTem (GRIST) model as an alternative to the default RRTMG (general ...
