Joseph A. Grim
Biography
Joseph A. Grim is currently a PhD student in the Department of Atmospheric Sciences at the University of Illinois. He is a research assistant under Dr. Robert Rauber and Dr. Greg McFarquhar studying the dynamic and microphysical effects within the trailing stratiform region of mesoscale convective systems. Joseph has also served as a teaching assistant, both at Illinois as well as at Purdue. Joseph earned his B.S. (2001) in Synoptic Meteorology from Purdue University. While attending Purdue University, Joseph was a member of the Purdue University Meteorological Society (1998-2001) and officer (2000-2001.) He is also a current member of the American Meteorological Society.

Professor: Robert M. Rauber
2000–2001 Teaching Assistant, Purdue University, West Lafayette
Taught lab section of EAS 109 – The Dynamic Earth
Prepared course material, taught and graded for lab section of EAS 109 – The
Dynamic Earth. This course used the modeling package Stella to simulate
many of the processes within the Earth system.
Taught EAS 230 - Lab in Atmospheric Science
Prepared course material, taught and graded for EAS 230 -Atmospheric
Observations and Measurements I (now called Lab in Atmospheric Science).
This course served as an overview lab course for weather analysis and
forecasting. Course material included: How to read and use different
meteorological measurement devices (e.g., thermometers, barometers,
psychrometers); observing and recording current weather
conditions, which included encoding and decoding METAR and upper air
observations, plotting and contouring meteorological variables (both subjective
and objective with the WXP weather analysis package), frontal analysis, and
using remote sensing platforms (radar and satellite); forecasting and
NOWcasting (including practice in issuing severe weather watches and
warnings); and preparing weather briefings.
Supervising Professor: Jon Schrage
