Data assimilation WRF/Chem Aerosol Aircraft
2018/5/16
A three-dimensional variational data assimilation system is implemented within the Weather Research and Forecasting/Chemistry model, and the control variables consist of eight species of the Model for...
Hydrological Modelling and data assimilation of Satellite Snow Cover Area using a Land Surface Model,VIC
Snowmelt Runoff Beas VIC model MODIS SCA Data Assimilation Direct Insertion Ensemble kalman filter (EnKF)
2016/11/30
The snow cover plays an important role in Himalayan region as it contributes a useful amount to the river discharge. So, besides estimating rainfall runoff, proper assessment of snowmelt runoff for ef...
STUDY ON ENVISAT ASAR DATA ASSIMILATION IN RICE GROWTH MODEL FOR YIELD ESTIMATION
Rice Yield Map Crop Model Radar Model Data Assimilation Optimization Algorithm Classification
2015/12/28
In this paper, a practical scheme for assimilation of multi-temporal and multi-polarization ENVISAT ASAR data in rice crop model to map rice yield has been presented. To achieve this, rice distributio...
CROP MODEL DATA ASSIMILATION WITH THE ENSEMBLE KALMAN FILTER FOR IMPROVING REGIONAL CROP YIELD FORECASTS
Crop model data assimilation Ensemble Kalman filter
2015/9/8
Uncertainty in spatial and temporal distribution of rainfall in regional crop yield
simulations comprises a major fraction of the error on crop model simulation results. In
this paper we used an Ens...
A FRAMEWORK OF A REMOTE SENSING DATA ASSIMILATION SYSTEM
Estimating environmental variables satellite observation
2015/9/8
Estimating environmental variables from satellite observation is often an ill-posed
inversion problem. There are currently multiple satellite sensors available for monitoring
land surface environmen...
The Impact of Multi-Sensor Data Assimilation on Plant Parameter Retrieval and Yield Estimation for Sugar Beet
yield modelling crop growth model PROMET
2015/5/6
Yield Maps are a basic information source for site-specific farming. For sugar beet they are not available as in-situ measurements. This gap of information can be filled with Earth Observation (EO) ...
Data assimilation techniques and modelling uncertainty in geosciences
Data assimilation (DA) Uncertainty 4D-VAR Minimization Cost function Kalman filter
2014/12/1
"You cannot step into the same river twice". Perhaps this ancient quote is the best phrase to describe the dynamic nature of the earth system. If we regard the earth as a several mixed systems, we wan...
Preliminary Results of a Data Assimilation System
Meteorological Analysis Forecasting Systems
2013/2/27
A data assimilation system combines all available information on the atmospheric state in a given time-window to produce an estimate of atmospheric conditions valid at a prescribed analysis time. Nowa...
Multivariate and Multiscale Data Assimilation in Terrestrial Systems: A Review
data assimilation multiscale multivariate modeling Ensemble Kalman Filter Particle Filter variational methods
2013/9/2
More and more terrestrial observational networks are being established to monitor climatic, hydrological and land-use changes in different regions of the World. In these networks, time series of state...
MULTIPLE HUMAN TRACKING IN COMPLEX SITUATION BY DATA ASSIMILATION WITH PEDESTRIAN BEHAVIOR MODEL
Observations Simulation Integration Image Sequences Tracking System Modelling
2014/4/28
A new method of multiple human tracking is proposed. The key concept is that to assume a tracking process as a data assimilation process. Despite the importance of understanding pedestrian behavior in...
