AOD, Aerosol, Data assimilation, Chemical species, WRF/Chem
2018/5/15
A three-dimensional variational data assimilation scheme is designed for satellite AOD based on the IMPROVE (Interagency Monitoring of Protected Visual Environments) equation. The observation operator...
In the elderly, meat protein assimilation from rare meat is lower than that from meat that is well done
protein metabolism amino acid bioavailability meat cooking elderly
2018/11/20
Background: Meat cooking conditions in in vitro and in vivo models have been shown to influence the rate of protein digestion, which is known to affect postprandial protein metabolism in the elderly.
New constraints on shergottite petrogenesis from analysis of Pb isotopic compositional space: Implications for mantle heterogeneity and crustal assimilation on Mars
shergottite Pb isotopes Martian geochemistry crustal assimilation mantle heterogeneity
2017/4/10
Geochemical studies of shergottites (Martian basalts) based on Rb-Sr, Sm-Nd, and Lu-Hf isotopic systematics have
provided clues to understanding the geochemical evolution of the Martian mantle and id...
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...

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...
OPERATIONAL ASSIMILATION OF SNOW DEPTH MAPS FOR IMPROVED REAL TIME RUNOFF NOWCASTING WITH SPATIALLY DISTRIBUTED HYDROLOGICAL MODELS
Operational assimilation snow depth maps
2015/9/8
Representative real time information on snow depth and snow water equivalent is needed for several
practical purposes, above all avalanche warning and flood forecast and control in spring. This study...
ASSIMILATION OF MODIS SNOW DATA IN A DETAILED MODEL OF ALPINE SNOW DYNAMICS AND SNOW HYDROLOGY
Alpine snow dynamics snow hydrology
2015/9/8
Snow as a water resource in mountains becomes more and more important as dryer and hotter conditions
prevail in many continental areas worldwide. Even maritime or temperate zones such as western and
...
PREPARING FOR THE ASSIMILATION OF REMOTE SENSING PRODUCTS BY LARGE-SCALE MODELS WITH UPDATED LAND SURFACE PROCESS SCHEMES
Data assimilation integration
2015/9/8
We present a computer efficient inversion software procedure enabling us to retrieve optimally, from
operational Terra broadband surface albedo products, a series of key vegetation characteristics su...
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
