DESCRIPTION:Atmospheric and Oceanic Sciences Departmental Seminar Series\n
 \npresents\n\n \n\nThe tropopause perspective in climate modelling: why cl
 oud heights really matter \n\na talk by\n\nProf. Roger Davies\n	Professor o
 f Climate Physics\n	Department of Physics\, The University of Auckland\, Ne
 wZealand\n	 \n\nThe MISR instrument on the Terra satellite has been measuri
 ng cloud heights since early 2000\, creating a unique climate data record 
 of over 19 years duration that is useful for a variety of regional climate
  studies. But why should cloud heights be of any interest to studies of gl
 obal climate or climate change?\n\nExplanations of the greenhouse effect o
 n surface temperature often have a surface perspective and focus on total 
 longwave opacity (which is not dependent on cloud height). If we invert th
 e conventional approach to adopt a tropospheric perspective\, we can direc
 tly answer the cloud height question. Perhaps surprisingly\, we also disco
 ver that water vapour is not as powerful a greenhouse gas as we might have
  expected.\n\n \n\nMonday July 08/ 3: 30 PM/ Burnside Hall/ Room 934\n
