ISEA 12 Session S3

S3: Equatorial lower and middle atmosphere

Monday, May 19, 2008 (morning)

Convener: G. Swenson
Co-conveners: T. Nakamura, J. Rttger

Description

This session will deal with (a) instrumental techniques, (b) structure, (c) dynamics and (d) new developments. Three invited talks shall be on items (a), (b) and (c). Contributed papers are solicited to be submitted on all four items, where item (d) would be particularly welcome. Papers should on the whole cover: (a) MST, IS, meteor and MF radars, as well as lidar and passive optical systems in the equatorial region, balloon and radiosondes, RASS technique and satellite remote sensing. (b) Irregularities, such as neutral turbulence, interaction with lower ionosphere plasma, temperature structure and chemical composition. Layering phenomena in the middle as well as in the lower equatorial atmosphere. (c) Troposphere-stratosphere-mesosphere coupling (convection, gravity waves etc.), equatorial waves and tides, QBO/ENSO, longitudinal variability, modeling and observations. (d) Any new ideas and recent as well as planned development of decent observing methods, networking, simulations and modeling are particularly welcome.

Keywords: structure and dynamics of the equatorial troposphere, stratosphere, and mesosphere, instruments, observations, simulations and modelling.
