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

Atmospheric 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]

Atmospheric 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.

Sensitivity Assessment of WRF Parameterizations over Europe

Proceedings, 2017
Evaluation of the performance of the parameterization schemes used in the WRF model is assessed for temperature and precipitation over Europe at 36 km by 36 km grid resolution using gridded data from the ECA & D 0.25° regular grid.

Multiscale numerical sensitivity simulations of a mesoscale gravity‐wave event

Quarterly Journal of the Royal Meteorological Society, EarlyView.
High‐resolution WRF simulations of the February 14–15, 1992 STORM‐FEST event show that mesoscale gravity‐wave genesis occurs via geostrophic adjustment within an upper‐level unbalanced jet, while wave ducting governs maintenance. High‐resolution (1 km), improved physical parameterization, and targeted sensitivity simulations demonstrate that upstream ...

Exploiting simultaneous observational constraints on mass and absorption to estimate the global direct radiative forcing of black carbon and brown carbon [PDF]

Atmospheric Chemistry and Physics, 2014
Atmospheric black carbon (BC) is a leading climate warming agent, yet uncertainties on the global direct radiative forcing (DRF) remain large. Here we expand a global model simulation (GEOS-Chem) of BC to include the absorption enhancement associated ...

Why does typhoon Noru (2022) possess severe rapid intensification as explored by the extended Sawyer–Eliassen equation?

Quarterly Journal of the Royal Meteorological Society, EarlyView.
As inferred from the Sawyer–Eliassen analyses, the intense diabatic heating located slightly inside the radius of maximum tangential wind (RMW) associated with a compact eyewall is mainly responsible for the severe RI of Noru, in contrast to typhoon Goni (2020) at a slower spinup despite similar RMW, due to the weaker diabatic heating. The severe RI of

Interpreting the ultraviolet aerosol index observed with the OMI satellite instrument to understand absorption by organic aerosols: implications for atmospheric oxidation and direct radiative effects [PDF]

Atmospheric Chemistry and Physics, 2016
Satellite observations of the ultraviolet aerosol index (UVAI) are sensitive to absorption of solar radiation by aerosols; this absorption affects photolysis frequencies and radiative forcing.

Model‐resolution impacts on all‐sky infrared radiance simulation and cloud‐dependent observation errors over Indonesia

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Numerical weather prediction over Indonesia is particularly challenging, because convection evolves rapidly and is modulated strongly by land–sea interactions across the maritime continent. To constrain forecasts better, there is substantial potential in assimilating all‐sky infrared observations, provided that the associated observation‐error ...
