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
