Lecturer    Profile

Dr. Melin Huang received her bachelor degree in Atmospheric   Sciences at National Taiwan University (NTU). After that, she switched to   study physics and received her M.S. degree in Physics at the same school,   NTU, and received her Ph.D. in Physics at University of Virginia, USA. After   her work in experimental physics for several years, in 2013 she joined Space   Sciences and Engineering Center (SSEC) at University of Wisconsin-Madison,   USA, working on researches related to atmospheric sciences.

Lecture    Abstract

Michelson   interferometer is an important instrument for satellite radiance   observations. It is built based on the principle of Fourier Transform and   designed to measure the emission of infrared radiation from atmosphere.   However, several types of errors would arise to affect the interferogram and   spectrum constructions. One of the errors is from extrinsic sampling effect,   which is sampling fluctuation between each digitized point. Currently uniform   magnitude of incident atmospheric radiation is assumed, implying symmetric   interferogram, yet asymmetric interferogram appears. This talk will discuss a   potential solution for solving this issue.
