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 ...
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...
A linear CO chemistry parameterization in a chemistry-transport model: evaluation and application to data assimilation

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...
