Assimilation of limb products, and synergistic exploitation

Oral

Ozone and water vapor in the lower stratosphere are important trace gases for atmospheric chemistry and radiative budget. The Stratospheric Aerosol and Gas Experiment (SAGE) missions have been crucial in monitoring the stratospheric ozone loss and the subsequent recovery as well as the trends in water vapor linked to surface temperature trends. The SAGE III instrument aboard the International...

Assimilation of limb products, and synergistic exploitation

Oral

ESA's Climate Change Initiative (CCI) programme was initiated around 2010 to address the difficulties in harmonising and merging climate data records (CDR) of Essential Climate Variables (ECV) and to provide climate modellers and researchers with stable long-term time series obtained by current and past European (and third-party) satellite missions. For over a decade now, the Ozone_cci team...

46. The SWOOSH version 3.0 data set: Updates, their implications for variability and trends, and preparing for the loss of the Aura Microwave Limb Sounder

Assimilation of limb products, and synergistic exploitation

Oral

The Stratospheric Water and Ozone Satellite Homogenized (SWOOSH) database is a monthly mean merged data set of vertically resolved ozone and water vapor data from a subset of limb profiling instruments operating since the 1980s. In this presentation, we summarize recent updates and improvements to SWOOSH that were made as part of the forthcoming version 3.0 release. Changes in version 3.0...

61. Studying transport and chemistry with the Stratospheric Composition Reanalysis of Aura Microwave Limb Sounder

Assimilation of limb products, and synergistic exploitation

Oral

NASA’s Global Modeling and Assimilation Office is producing a new reanalysis of stratospheric composition by assimilating water vapor, hydrogen chloride, nitric acid, nitrous oxide, and ozone profiles from Aura Microwave Limb Sounder (MLS). Named M2-SCREAM (MERRA-2 Stratospheric Composition Reanalysis of Aura MLS), this product covers the period between late 2004 and the present. Global...
