Revisiting particle dry deposition and its role in radiative effect estimates
2020
Proceedings of the National Academy of Sciences of the United States of America
We present a revised observationally driven parameterization for regional and global aerosol models. ...
Dry deposition is a significant source of aerosol uncertainty in global chemical transport and climate models. ...

Parameterization of biogeochemical sediment–water fluxes using in situ measurements and a diagenetic model
2016
Biogeosciences
Here, we apply a method that efficiently parameterizes sediment–water fluxes of oxygen, nitrate and ammonium by combining in situ measurements, a diagenetic model and a parameter optimization method. ...
Yet, sediment–water fluxes of chemical species are often parameterized crudely in coupled physical–biogeochemical models, using simple linear parameterizations that are only poorly constrained by observations ...

The Nature, Theory, and Modeling of Atmospheric Planetary Boundary Layers
2011
Bulletin of The American Meteorological Society - (BAMS)
P lanetary boundary layers (PBLs) represent sensitive and changeable coupling agents that regulate the fluxes of energy, momentum, and matter between the atmosphere and land or sea over a range of scales ...
With the development of high-resolution models, requirements for PBL schemes have dramatically increased, making them a key element of modern model suites that address essential environmental features. ...

Taking Account of "Unknown Unknowns"
2010
Ground Water
-Donald Rumsfeld, Former United States Secretary of Defense Water issues-quantity and quality-are expected to ...
Finally, although the invariable presence of unknown unknowns undermines any hope of calculating hard and fast error bars around a model prediction, such calculations can still have value; perhaps the ...
With such a view, the "limitations and assumptions" section of a modeling report becomes higher profile, and lists specific sources of known and unaccounted for structural error. ...

Journal of Geophysical Research - Solid Earth
This measurement of seismic anisotropy and gradients reflects the effects of both plate formation and evolution processes on seismic velocity structure in mature oceanic lithosphere, and can serve as a ...
Further, many refraction studies observe a fast direction of anisotropy rotated several degrees with respect to the paleospreading direction, suggesting that upper mantle anisotropy records processes other ...

Improved determination of coastal water constituent concentrations from MERIS data
2005
IEEE Transactions on Geoscience and Remote Sensing
The procedure is very fast as it takes advantage of the Jacobian which is a byproduct of the NN calculation. in 1989, where he is currently a Research Scientist in the bio-optical remote sensing group, ...
Two NNs are trained with simulated reflectances: 1) invNN to emulate the inverse model (reflectances, geometry) concentrations and 2) forwNN to emulate the forward model (concentrations, geometry) reflectances ...
To become able to use the inverse modeling technique operationally the solution was to parameterize the inverse model. The construction of such a parameterization is rather computer time consuming. ...
