2007 Workshop:MLT spatial and temporal variabilities

Introduction
Characteristics and causes of MLT spatial and temporal variabilities
The combination of ground-based and satellite observations under the TIMED/CEDAR program is providing unprecedented spatial and temporal coverage of the Mesosphere and Lower Thermosphere (MLT) region. The ground-based instruments provide measurements of MLT winds and temperatures at specific geographic locations over many local times and complement the TIMED instruments, which provide similar measurements globally at one or two local times on any given day. TIMED observations also provide pressure, density, and other geophysical parameters critical to understanding MLT energetics. When combined, these two data sets can provide true mean fields and a higher-time-resolution 3-D picture of atmospheric waves, especially tides, in order to understand the processes that govern MLT coupling to the lower and upper atmosphere and ionosphere. In addition, CEDAR investigators have collected MLT data over almost two solar cycles with >5 years of coincident, continuous TIMED observational data. The focus of this workshop is to foster collaboration between satellite, ground-based, and modeling teams to study the MLT energetics and basic structure, including zonal mean, tides, and planetary waves and the causes of their temporal variabilities (on daily, seasonal, QBO, and solar cycle time scales). We encourage people to present recent observations and research findings that can lead to fruitful collaborations.
