The research programme contains the construction of global, monthly tables of wind and its variability in the atmosphere up to 100 km. This task is based on already existing models of winds and tides in the mesosphere/lower thermosphere, uses global analyses from Met Office reanalyses, and combines these analyses using a circulation model to include the mesosphere that is not well covered with measurements.

In summary, the project research programme will consist of the following tasks:

1.    Update of the mesosphere/lower thermosphere empirical mean wind model
2.    Construction of a stratospheric mean wind model
3.    Including stationary planetary waves in models
4.    Calculating the degree of variability of winds
5.    Construction of a semiempirical model of the entire middle atmosphere, through assimilation of the zonal mean winds into a circulation model
6.    Validation or the results using ground-based and space-based measurements

The project combines the efforts of 2 INTAS and 2 NIS partners, each having long experience in establishing empirical climatologies of the middle atmosphere, ground-based and space-based measurements and numerical modelling. The length of the project will be 30 months. During this time interval an important step towards new and updated reference models will be performed.
