26 June 2008HIRDLS Science Meeting3 HIRDLS: Scientific Objectives Understand chemical processes, transports and mixing in the upper-troposphere/lower stratosphere. Understand chemical processes, transports and mixing in the upper-troposphere/lower stratosphere. Understand stratosphere-troposphere exchange of a variety of gases/aerosols at a fine scales Understand stratosphere-troposphere exchange of a variety of gases/aerosols at a fine scales Better evaluate the budgets of; momentum, energy, heat and PV, which help mitigate this exchange Better evaluate the budgets of; momentum, energy, heat and PV, which help mitigate this exchange To provide data to help constrain and validate models.
