Final deadline

The new final deadline for submission is 31.10.2010.

AMT special issue - deadline extended!

The deadline for submission to the special issue "Atmospheric Remote Sensing using Limb-observations" in Atmospheric Measurement Technique (AMT) has been extended. The new deadline is 31.8.2010.

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.

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.

Limb Special Issue

The special issue "Atmospheric Remote Sensing using Limb-observations" in Atmospheric Measurement Techniques (AMT) is now open. Note that the focus of the AMT is on measurement techniques, retrievals, validation etc. AMT does not publish scientific applications and science issues.

Please, submit your manuscripts here. In submission, remember to choose the correct special issue.

Deadline for submissions: 31.5.2010

The editors are:

Christian von Savigny, IUP, Bremen

Erkki Kyrola, FMI, Helsinki


The FMI's organising team of the 5th Limb meeting would like to thank all of you for your active participation and excellent presentations. There are also a few photos of the conference available.

The information about the proposed special publication and the SPARC report will be announced on this site later on. The 6th limb meeting will take place in 2011 in Japan.


All presentations are now online.

Book of Abstracts

The book of abstracts is now available. You will receive a printed copy from the registration desk at the beginning of the conference.
