Data assimilation method offers improved hurricane forecasting（图）
Data assimilation method hurricane forecasting
2019/10/21
In 2017, operational models predicted that Hurricane Harvey would become a Category 1 hurricane. Instead, it became a massive Category 4 storm just before it made landfall, and tied Hurricane Katrina ...
An analysis of the collection 5 MODIS over-ocean aerosol optical depth product for its implication in aerosol assimilation
the collection 5 MODIS over-ocean aerosol optical depth product aerosol assimilation
2011/1/20
As an update to our previous use of the collection 4 Moderate Resolution Imaging Spectroradiometer (MODIS) over-ocean aerosol optical depth (AOD) data, we examined ten years of Terra and eight years o...
A decadal regional and global trend analysis of the aerosol optical depth using a data-assimilation grade over-water MODIS and Level 2 MISR aerosol products
the aerosol optical depth a data-assimilation grade over-water MODIS Level 2 MISR aerosol products
2010/11/30
Using the ten-year (2000–2009) Data-Assimilation (DA) quality Terra MODIS and MISR aerosol products, as well as 7 years of Aqua MODIS, we studied both regional and global aerosol trends over oceans. T...
Observation operator for the assimilation of aerosol type resolving satellite measurements into a chemical transport model
aerosol type satellite measurements a chemical transport model
2010/11/29
Modelling of aerosol particles with chemical transport models is still based mainly on static emission databases while episodic emissions cannot be treated sufficiently. To overcome this situation, a ...
Sensitivity tests for an ensemble Kalman filter for aerosol assimilation

2010/8/16
We present sensitivity tests for a global aerosol assimilation system utilizing AERONET observations of AOT (aerosol optical thickness) and AAE (aerosol Ångström exponent). The assimilation...
A linear CO chemistry parameterization in a chemistry-transport model: evaluation and application to data assimilation
A linear CO chemistry parameterization a chemistry-transport model data assimilation
2010/8/16
This paper presents an evaluation of a new linear parameterization valid for the troposphere and the stratosphere, based on a first order approximation of the carbon monoxide (CO) continuity equation....
Anthropogenic aerosol radiative forcing in Asia derived from regional models with atmospheric and aerosol data assimilation
Anthropogenic aerosol radiative Asia regional models atmospheric aerosol data assimilation
2010/8/16
An estimate of monthly 3-D aerosol solar heating rates and surface solar fluxes in Asia from 2001 to 2004 is described here. This product stems from an Asian aerosol assimilation project, in which a) ...
Applying an ensemble Kalman filter to the assimilation of AERONET observations in a global aerosol transport model
Kalman filter assimilation AERONET observations global aerosol transport model
2010/3/16
We present a global aerosol assimilation system based on an Ensemble Kalman filter, which we believe leads to a significant improvement in aerosol fields. The ensemble allows realistic, spatially and ...
Impact of energetic particle precipitation on stratospheric polar constituents: an assessment using monitoring and assimilation of operational MIPAS data
energetic particle precipitation stratospheric polar constituents MIPAS
2010/2/21
In 2003, strong energetic particle precipitation (EPP) events occurred producing massive amounts of ionization which affected the polar region significantly perturbing its chemical state down to the m...
Data assimilation of CALIPSO aerosol observations
Data assimilation CALIPSO aerosol observations
2010/1/18
We have developed an advanced data assimilation system for a global aerosol model with a four-dimensional ensemble Kalman filter in which the Level 1B data from the Cloud-Aerosol Lidar and Infrared Pa...
The 15th century Arctic warming in coupled model simulations with data assimilation

2009/12/3
An ensemble of simulations of the climate of the past millennium conducted with a three-dimensional climate model of intermediate complexity are constrained to follow temperature histories obtained f...
Using adjoint sensitivity as a local structure function in variational data assimilation
adjoint sensitivity local structure function variational data assimilation
2009/11/12
One approach recently proposed in order to improve the forecast of weather events, such as cyclogenesis, is to increase the number of observations in areas depending on the flow configuration. These a...
An operational system for the assimilation of the satellite information on wild-land fires for the needs of air quality modelling and forecasting
operational system satellite information wild-land fires
2009/9/23
This paper investigates a potential of two remotely sensed wild-land fire characteristics: 4-μm Brightness Temperature Anomaly (TA) and Fire Radiative Power (FRP) for the needs of operational chemical...

2009/8/7
A simple data assimilation algorithm based on statistical interpolation has been developed and coupled to a long-range chemistry transport model, the Danish Eulerian Operational Model (DEOM), applied ...
First steps towards the assimilation of IASI ozone data into the MOCAGE-PALM system
assimilation IASI ozone data MOCAGE-PALM system
2009/8/7
With the use of data assimilation, we study the quality of the Infrared Atmospheric Sounding Interferometer (IASI) total ozone column measurements. The IASI data are provided by the inversion of IASI ...
