HIRDLS

Aims and objectives

Science goals using HIRDLS data include the determination of:

  • fluxes of mass and chemical constituents between the troposphere and stratosphere

  • chemical processing, transport and mixing, particularly in the lower stratosphere

  • momentum, energy and potential vorticity balances of the middle atmosphere

  • geographically and seasonally unbiased long-term climatologies and interannual variability of middle atmosphere temperature, constituents, dynamical fields and gravity waves

  • tropospheric cloud heights

  • tropospheric temperature and water vapour retrievals, possibly in conjunction with other EOS (Earth Observing System) sounders

  • diagnostic studies of atmospheric dynamics, chemistry, and transport processes to test and improve models of these processes, especially at those smaller scales for which there are now no data to check the models' chemical or dynamical behaviour
