             abstract = "Recent years have shown a continuing interest in studies of the 
                         mesosphere-lower thermosphere region at low latitudes, with more 
                         than 50 papers dealing specifically with this area published over 
                         the past 5 years. Experimental ground-based work has been carried 
                         out mainly in South America and the Caribbean, India and the 
                         Pacific areas. Subjects of interest include gravity waves, tides 
                         and planetary waves, the temperature structure of the mesopause 
                         region, with special reference to temperature inversions and the 
                         two-level mesopause, sporadic neutral layers and their 
                         relationship with ionized layers, the possible effects of the 
                         micrometeoroid influx, and long-term trends in the MLT region. 
                         Experimental techniques in use include MF, MST and meteor radar, 
                         lidar, airglow (including satellite-borne limb-scanning 
                         measurements) and rocket-borne instruments. Airglow imaging has 
                         shown itself to be a particularly useful technique, mainly for 
                         studying gravity wave propagation in the MLT region. This paper 
                         will present highlights of recent work and will discuss some of 
                         the problems which remain to be resolved.",
