AGU Special Session
There will be a special session on limb techniques at the Spring American Geophysical Union (AGU) general meeting which will take place August 8-13 in Foz de Iguassu, Brazil. The session is posted on the AGU website and is open for submissions until March 31st. The session is listed as A14. Limb techniques for monitoring trace gas and aerosol vertical distribution.
Description:
This session deals with monitoring trace gas and aerosol vertical distribution in the Earth middle atmosphere using spectral
measurements of the limb radiance in the UV/visible/IR (scattered sunlight, solar/lunar/stellar occultation) and IR,
MW and sub-mm (emission). A series of space-borne instruments have used this technique over the past 30 years
(from SAGE to SOFIE/AIM) and more are being planned (OMPS/LP, PREMIER). The proposed session is aimed at bringing together
researchers in this field and providing a forum for discussion. Topics will include instrument design,
inversion algorithm, forward modeling, validation, and data usage (assimilation, trend, dynamics and chemistry)
This session seeks contributions that describe (i) tools (radiative transfer models), (ii) methods (retrieval algorithms, stray light mitigation, tangent height registration), (iii) data analysis results from existing Limb instruments (trace gas species profiles, aerosol profiles), as well as (iv) any new concepts which could improve the Limb technique beyond the present State-of-the-Art.
