Global Thermosphere Mapping Study

Project Description
The GTMS ( Global Thermosphere Mapping Study ) was an
international cooperative enterprise scheduled for 1985-1986
with several short campaigns. Several ground-based observational
networks were involved in the GTMS campaigns, namely meteor
radars, ionospheric wind stations, incoherent scatter radars,
etc. The main goal of the program was to obtain a global map of
thermosphere winds for main seasonal periods.
