12.815 Atmospheric Radiation
Fall 2006
The dependence of light transmission through the atmosphere on light wavelength. Because of Earth's atmosphere, many wavelengths of radiation cannot be observed by detectors or telescopes on Earth's surface. Only visible light, radio waves, and some ultraviolet light reaches sea level. (Image courtesy of NASA.)
Course Highlights
This course features complete lecture notes and computational exercises in assignments section.
Course Description
This is an introduction to the physics of atmospheric radiation and remote sensing including use of computer codes. Subjects covered include: radiative transfer equation including emission and scattering, spectroscopy, Mie theory, and numerical solutions. We examine the solution of inverse problems in remote sensing of atmospheric temperature and composition.

Exercises
Radiative Transfer (PDF)
HITRAN (PDF)
The HITRAN data base can be downloaded (together with the HAWKS program) from the Web site.
The HAWKS program can be used for the "Search" and "Plot" portions of the exercise together with the HITRAN data base. To do the "Trans" portion of the exercise, it is necessary to purchase the PCLnWin code which is available from ONTAR Corporation for purchase. The ONTAR Web site and their current price list quotes $4,900.00 for PCLnWin ver 3.0.
Pcmodwin (PDF)
The MODTRAN code is necessary to perform this exercise and it is available for purchase from ONTAR Corporation. Their current price list quotes $2,400.00.
Mie Theory (PDF)
This software can be downloaded for free from the following Web site: ftp://climate1.gsfc.nasa.gov/wiscombe/Single_Scatt/Homogen_Sphere/Exact_Mie/
Multiple Scattering (PDF)
This software can be downloaded for free from the following Web site: ftp://climate1.gsfc.nasa.gov/wiscombe/Multiple_Scatt/DISORT1.3/
Remote Sensing (PDF)
The first part of this exercise requires that the student have access to a matrix inversion computer program. The second part requires the use of PCModWin which was previously used for PCmodwin exercise.
