The Journal of Physics in Canada dedicates issue to the science of planetary remote sensing.

The September / October issue of Physics in Canada discusses the science of planetary remote sensing. Remote sensing has proven useful in areas such as monitoring weather systems, managing natural resources and obtaining detailed road maps that affect our daily lives. Canada is a leader in remote sensing, and this issue describes several techniques and research in progress across Canada.

Among the articles presented in this issue of Physics in Canada is the work of Dr. Philippe M. Teillet, research scientist at the Canada Centre of Remote Sensing (CCRS) in the department of Natural Resources Canada.

Here is a short quote from Dr. Teillet's paper, titled: Satellite Image Radiometry: from Photons to Calibrated Earth Science Data:

"Today's remote sensing satellite systems yield digital images that provide unprecedented observations of the earth from space that are both synoptic and detailed in nature. There is tremendous interest in the use of these images to derive information about current states of geophysical and biophysical variables and to monitor their changes. This article outlines the key steps needed to ensure that terrestrial variables retrieved from optical satellite sensor systems are calibrated to a common physical scale. The emphasis is placed on the multiple methodologies used post-launch to convert digital image data to calibrated products for the user community. The article focuses on reflectance, land surface parameter of wide interest, as an example."
