Principal Component Analysis Numerical Model Errors Analogue-dynamical Prediction
2011/8/16
Abstract: A new prediction error correction scheme based on 74 circulation characteristics data provided by Weather Diagnostic Forecasting Division of National Climate Center, which is designed to dev...
The use of IASI data to identify systematic errors in the ECMWF forecasts of temperature in the upper stratosphere
IASI data systematic errors the ECMWF temperature the upper stratosphere
2011/2/25
Since data from the Infrared Atmospheric Sounding Interferometer (IASI) became available in 2007, a number of papers have appeared in the literature which have reported relatively large discrepancies ...
High resolution modeling of CO2 over Europe: implications for representation errors of satellite retrievals
CO2 Europe satellite retrievals
2010/1/18
Satellite retrievals for column CO2 with better spatial and temporal sampling are expected to improve the current surface flux estimates of CO2 via inverse techniques. However, the spatial scale misma...
Estimating trajectory uncertainties due to flow dependent errors in the atmospheric analysis
Estimating trajectory uncertainties flow dependent errors atmospheric analysis
2009/12/3
The uncertainty of a calculated trajectory is dependent on the uncertainty in the atmospheric analysis. Using the Ensemble Transform method (originally adapted for ensemble forecasting) we sample the ...

Assessing temporal clear-sky errors in assimilation of satellite CO2 retrievals using a global transport model
Assessing temporal clear-sky errors satellite CO2 global transport model
2009/5/15
The Orbiting Carbon Observatory (OCO) and the Greenhouse gases Observing SATellite (GOSAT) will make global observations of the total column dry-air mole fraction of atmospheric CO2 (XCO2) starting in...
A quantitative analysis of grid-related systematic errors in oxidising capacity and ozone production rates in chemistry transport models
grid-related systematic errors oxidising capacity ozone production rates chemistry transport models
2009/3/5
Limited resolution in chemistry transport models (CTMs) is necessarily associated with systematic errors in the calculated chemistry, due to the artificial mixing of species on the scale of the model ...
Spatial and temporal characterization of SCIAMACHY limb pointing errors during the first three years of the mission
Spatial and temporal characterization SCIAMACHY limb pointing errors mission
2009/2/18
Limb scattering retrievals of atmospheric minor constituent profiles require highly accurate knowledge of the tangent heights during the measurements. The limb scattering measurements of the Scanning ...
Systematic errors in global air-sea CO2 flux caused by temporal averaging of sea-level pressure
Systematic errors global air-sea CO2 flux temporal averaging sea-level pressure
2009/2/11
Long-term temporal averaging of meteorological data, such as wind speed and air pressure, can cause large errors in air-sea carbon flux estimates. Other researchers have already shown that time averag...
Evidence of systematic errors in SCIAMACHY-observed CO2 due to aerosols
systematic errors SCIAMACHY-observed CO2 aerosols
2009/1/14
SCIAMACHY CO2 measurements show a large variability in total column CO2 over the Sahara desert of up to 10%, which is not anticipated from in situ measurements and cannot be explained by results of at...
The effect of systematic measurement errors on atmospheric CO2 inversions: a quantitative assessment
systematic measurement errors atmospheric CO2 inversions quantitative assessment
2008/12/30
Surface-atmosphere exchange fluxes of CO2, estimated by an interannual atmospheric transport inversion from atmospheric mixing ratio measurements, are affected by several sources of errors, one of whi...
Modelling representation errors of atmospheric CO2 mixing ratios at a regional scale
atmospheric CO2 regional scale
2008/11/26
Inverse modelling of carbon sources and sinks requires an accurate quality estimate of the modelling framework to obtain a realistic estimate of the inferred fluxes and their uncertainties. So-called ...
Technical Note: Interference errors in infrared remote sounding of the atmosphere
infrared remote sounding atmosphere
2008/11/12
Classical error analysis in remote sounding distinguishes between four classes: "smoothing errors," "model parameter errors," "forward model errors," and "retrieval noise errors". For infrared soundin...
