Rolando is Senior Scientist in the Atmospheric Chemistry Observations and
Modeling Laboratory (ACOM) of the NSF National Center for Atmospheric
Research (NSF NCAR). Over the last decades, he has led the study of
stratospheric chemistry at NCAR and continues to engage scientists from early
career to established international collaborations in this critical element for
understanding our atmosphere.

Over his impressive career, Rolando has fundamentally advanced the
atmospheric sciences through study of observational, theoretical and numerical
studies of ozone and other atmospheric constituents; modeling and
observational studies of atmospheric waves; the effects of waves on the
circulation and transport of chemical constituents in the middle atmosphere; and
numerical modeling of the global atmospheric circulation and chemistry-climate
interactions. He is a co-developer of the Whole Atmosphere Community Climate
Model (WACCM). He has served as chair of the Whole Atmosphere Working
Group and continues to be involved in the development of WACCM.

He has mentored many students and early career scientists and served on
numerous dissertation committees. He was chair of the Middle Atmosphere
Committee of the American Meteorological Society, and member of the
Committee on Solar Terrestrial Research of the U.S. National Research Council.
He was named Haurwitz Memorial Lecturer for 2010 by the American
Meteorological Society; he is a Fellow of the American Geophysical Union and
the American Meteorological Society.
