The overall question is: Is the climate of the mesopause region
(80-100km) changing? If so, how and why?


The objectives of NDMC are

  • Identify and quantify climate changes by monitoring key parameters
    such as temperatures in the mesopause region, airglow brightness for
    the early characterization of climate signals; Identify and quantify
    variability at different time scales such as seasonal variations and
    solar cycle effects.
  • Detection of solar activity effects at all time scales (“Space Weather”)
  • Answering other scientific questions related to atmospheric dynamics
    at different time scales including the description and the causes of the
    variability of periodic and quasi-periodic processes:
    • acoustic and gravity waves,
    • tides and planetary waves, and
    • seasonal and interannual variations. Also,
    • episodic events caused by external forcing shall be monitored.


  • Validation of satellite instruments and its use for intercomparison of
    ground-based instruments
  • Cooperation in the development of instrumentation
