Sinéad Louise Farrell joined the Department of Geographical Sciences as an associate professor in the fall of 2019. Dr. Farrell has a joint appointment with the Department of Atmospheric and Oceanic Science. Dr. Farrell received her Ph.D. in Space and Climate Physics from University College London in 2007. Her primary fields of study are cryospheric sciences and remote sensing. She is a principal investigator on the NASA ICESat-2 Science Team and a member of the Mission Advisory Group for the Copernicus Polar Ice and Snow Topography Altimeter. Prior to joining the Department of Geographical Sciences, Dr. Farrell was an Associate Research Scientist at the Earth System Science Interdisciplinary Center (ESSIC), at the University of Maryland. She is also a visiting scientist with the NOAA Laboratory for Satellite Altimetry, College Park, MD.

AOSC440/GEOG440: Polar Remote Sensing
https://app.testudo.umd.edu/soc/202108/AOSC/AOSC440/0.pdf
The harsh environment of the vast polar regions makes them some of the most inaccessible places on Earth. With widespread environmental change already underway, satellite remote sensing provides the only means by which to obtain year-round observations of the polar climate system. The objective of this course is to provide students with an overview of polar remote sensing techniques, including the physical principles of active and passive sensors, orbits, electromagnetic radiation, atmospheric transmission, calibration and validation. We will focus on measurements of the polar oceans, sea ice, glaciers, ice sheets, snow and permafrost, and examine the response of the cryosphere to climate change.
