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 ...
