DESCRIPTION:Atmospheric and Oceanic Sciences Departmental Seminar Series\n
 \npresents\n\nEvaluating Land-Atmosphere Interactions during LAFE\n\na tal
 k by\n\nDave Turner\n	Meteorologist\, \n	National Oceanic and Atmospheric Ad
 ministration\,\n	U.S. Department of Commerce\, Washington\, DC\n\nThe inter
 actions between the land surface and the atmosphere needs to be represente
 d in all numerical weather prediction and climate models. The Land-Atmosph
 ere Feedback Experiment (LAFE) was conducted at the ARM SGP to collect a c
 omprehensive dataset to evaluate the similarity relationships used to repr
 esent these processes in most numerical models. This seminar will present 
 an overview of the LAFE campaign\, present some observational results\, an
 d demonstrate how observations like this can be used to improve similarity
  relationships. Furthermore\, the 2017 solar eclipse that occurred in the 
 middle of the LAFE experiment\, and we show that the operational High-Reso
 lution Rapid Refresh (HRRR) weather forecast model is not adequately captu
 ring these land-atmosphere interactions.\n\nDr. David Turner received his 
 BA and MS in mathematics at Eastern Washington University\, after which he
  started working for the Department of Energy’s Atmospheric Radiation Meas
 urement (ARM) program at Pacific Northwest National Lab (PNNL). After 7 ye
 ars at PNNL\, he went to the University of Wisconsin - Madison (UW)\, wher
 e he received a PhD in atmospheric science in 2003. He joined NOAA in 2010
  and is meteorologist at the Earth System Research Laboratory. He is the p
 rogram manager for NOAA’s Atmospheric Science for Renewable Energy Program
  and the lead of the Model Assessment Section within the Global Systems Di
 vision.\n\nDr. Turner’s research interests include improving radiative tra
 nsfer models\, remote sensing with active and passive sensors\, retrieval 
 theory\, studying the thermodynamic and dynamic structure of the boundary 
 layer and its evolution\, characterizing the properties and processes in m
 ixed-phase clouds and especially those in the Arctic\, and using observati
 ons to improve operational weather prediction models.\n\nMonday Nov 11/ 3:
 30 PM/ Burnside Hall/ Room 934\n
