Atmospheric inverse modeling with known physical bounds: an example from trace gas emissions
Atmospheric inverse modeling physical bounds
2014/12/18
Many inverse problems in the atmospheric sciences involve parameters with known physical constraintsExamples include nonnegativity (e.g., emissions of some urban air pollutants) or upward limits impli...
The Norwegian Earth System Model, NorESM1-M – Part 1: Description and basic evaluation of the physical climate
Norwegian Earth System Model Description and basic evaluation the physical climate
2014/12/12
The core version of the Norwegian Climate Center's Earth System Model, named NorESM1-M, is presented. The NorESM family of models are based on the Community Climate System Model version 4 (CCSM4) of t...
Normal and Extreme Sedimentation and Physical Processes in Lake Tuborg, Ellesmere Island, Nunavut

2014/10/22
Lake Tuborg is a large lake on west-central Ellesmere Island, Nunavut. Part of the lake is meromictic, and contains trapped saltwater below about 55 m depth. The lake receives meltwater and sediments ...
Banded Iron Formations (BIFs) and Associated Sediments Do Not Reflect the Physical and Chemical Properties of Early Precambrian Seas
Early Precambrian BIF Non-Marine Polar Regions
2013/3/7
Ring-in-ring structures in Australian Early Precambrian banded iron formation (BIF) were identified as bubbling mud wavelets, which lithified during temporary exposure, contradicting the alleged BIF d...
Exploitation of cloud top characterization from three-channel IR measurements in a physical PMW rain retrieval algorithm
three-channel IR measurements physical PMW
2010/1/27
Rainfall intensity estimates by passive microwave (PMW) measurements from space perform generally better over the sea surface with respect to land, due to the problems in separating true rain signatur...
Simulation of the specific surface area of snow using a one-dimensional physical snowpack model:implementation and evaluation for subarctic snow in Alaska
specific surface area snow one-dimensional physical snowpack model subarctic snow Alaska
2010/2/3
The specific surface area (SSA) of the snow constitutes a powerful parameter to quantify the exchange of matter and energy between the snow and the atmosphere. However, currently no snow physics model...
Temporal responses of coastal hypoxia to nutrient loading and physical controls
Temporal responses coastal hypoxia nutrient loading physical controls
2010/1/21
The incidence and intensity of hypoxic waters in coastal aquatic ecosystems has been expanding in recent decades coincident with eutrophication of the coastal zone. Worldwide, there is strong interest...
Influence of weathering and pre-existing large scale fractures on gravitational slope failure: insights from 3-D physical modelling
weathering and pre-existing large scale fractures gravitational slope failure 3-D physical modelling
2009/12/14
The shallower one represents the zone subject to homogeneous weathering and is made of low strength material of compressive strength σl. The deeper (core) part of the model is stronger and simulates i...
Physical modelling of the interaction between powder avalanches and defence structures
Physical modelling powder avalanches defence structures
2009/12/9
In order to better understand the interaction between powder snow avalanches and defence structures, we carried out physical experiments on small-scale models. The powder snow avalanche was simulated ...
