The prior information used for Level 2 (L2) retrievals in the thermal infrared can influence the quality of the retrievals themselves and. therefore. their further assimilation in atmospheric composition models. In this study we evaluate the differences between assimilating L2 ozone profiles and Level 1 (L1) radiances from the Infrared Atmospheric Sounding Interferometer (IASI). https://ashleyshomestores.shop/product-category/30-warming-drawer/
