Towards reduced uncertainty in catchment nitrogen modelling: quantifying the effect of field observation uncertainty on model calibration
INCA nitrogen model parameter uncertainty
2009/3/6
The value of nitrogen (N) field measurements for the calibration of parameters of the INCA nitrogen in catchment model is explored and quantified. A virtual catchment was designed by running INCA with...
Parametric sensitivity and uncertainty analysis of dimethylsulfide oxidation in the clear-sky remote marine boundary layer
Parametric sensitivity dimethylsulfide oxidation clear-sky remote marine boundary layer
2009/2/11
Local and global sensitivity and uncertainty methods are applied to a box model of the dimethylsulfide (DMS) oxidation cycle in the remote marine boundary layer in order to determine the key physical...
Determining the Minimum Uncertainty State of Nonclassical Light
the Minimum Uncertainty State Nonclassical Light
2010/4/9
Squeezing experiments which are capable of creating a minimum uncertainty state during the nonlinear process, for example optical parametric amplification, are commonly used to produce light far below...
Search for evidence of trend slow-down in the long-term TOMS/SBUV total ozone data record: the importance of instrument drift uncertainty
long-term TOMS/SBUV total ozone instrument drift uncertainty
2009/1/15
We have developed a merged ozone data set (MOD) for the period October 1978 through June 2006 combining total ozone measurements (Version 8 retrieval) from the TOMS (Nimbus 7, Earth Probe) and SBUV/SB...
Uncertainty analysis for estimates of the first indirect aerosol effect
Uncertainty analysis first indirect aerosol effect
2009/1/14
The IPCC has stressed the importance of producing unbiased estimates of the uncertainty in indirect aerosol forcing, in order to give policy makers as well as research managers an understanding of the...
Phenomenological Implications of the Generalized Uncertainty Principle
Phenomenological Implications Generalized Uncertainty Principle
2010/4/13
Various theories of Quantum Gravity argue that near the Planck scale, the Heisenberg Uncertainty Principle should be replaced by the so called Generalized Uncertainty Principle (GUP). We show that the...
Exploring uncertainty in glacier mass balance modelling with Monte Carlo simulation
uncertainty glacier mass balance modelling Monte Carlo simulation
2010/2/4
By means of Monte Carlo simulations we calculated uncertainty in modelled cumulative mass balance over 400 days at one particular point on the tongue of Morteratsch Glacier, Switzerland, using a glaci...
Optimal design under uncertainty of a passive defense structure against snow avalanches: from a general Bayesian framework to a simple analytical model
Optimal design a passive defense structure snow avalanches a general Bayesian framework a simple analytical model
2009/12/30
For snow avalanches, passive defense structures are generally designed by considering high return period events. In this paper, taking inspiration from other natural hazards, an alternative method bas...

Using maps of city analogues to display and interpret climate change scenarios and their uncertainty
city analogues climate change scenarios and their uncertainty
2009/12/30
We describe a method to represent the results of climate simulation models with spatial analogues. An analogue to a city A is a city B whose climate today corresponds to A's simulated future climate. ...
Determination of 9Be in geological standard samples, JA-2 and JB-2, and of 9Be and 10Be in a basaltic rock sample for evaluation of uncertainty involved in 10Be/9Be ratio measurements
10Be 9Be ICP-MS AMS uncertainty
2017/8/10
We determined the concentrations of 9Be in JB-2 and JA-2 geological standard samples using an inductively coupled plasma mass spectrometer (ICP-MS). We determined 9Be abundance in standard samples of ...
