The BOReal Ecosystem-Atmosphere Study (BOREAS) Staff Science Aircraft Data Acquisition Program focused on providing
the research teams with the remotely sensed aircraft data products they needed to compare and spatially extend point results.
The MODIS Airborne Simulator (MAS) images, along with other remotely sensed data, were collected to provide spatially extensive
information over the primary study areas. This information includes biophysical parameter maps such as surface reflectance
and temperature. Collection of the MAS images occurred over the study areas during the 1994 field campaigns. The level-2 MAS
data cover the dates of 21-Jul-1994, 24-Jul-1994, 04-Aug-1994, and 08-Aug-1994. The data are not geographically/geometrically
corrected; however, files of relative X and Y coordinates for each image pixel were derived by using the C130 navigation data
in a MAS scan model. The data are provided in binary image format files.

Proposed Definitions of Some Technical Terms Frequently Used in Microwave Radiometry for Remote Sensing

The use of microwave radiometry for remote sensing is a relatively young field. As a result, there are no standard definitions
of many frequently used technical terms; a lot of which are conventional usages carried-over from optical remote sensing, and
a lot more are shared with electrical or microwave engineering. Sometimes the divergent notions and assumptions originating
from a different field may cause ambiguity or confusions. It is proposed that we establish a list of frequently used terms, together
with their ’standard’ definitions and hope that they will gradually gain general acceptance by the remote sensing community. It
would be even more useful if the IEEE community can set up a standard committee of sort to develop and maintain the standards.
To minimize the effort, the existing terms should be kept or reinterpreted as much as possible. For example, the term ’Instantaneous
Field of View’ (IFOV), originally coming from the optical remote sensing field, is now appearing in microwave remote sensing
literature frequently. The IFOV refers to the ’beam width’ or the ’diameter’ of the beam’s geometrical projection on earth surface.
Since the definition of ’beam width’ is different for an optical system versus a microwave antenna, the use of IFOV in microwave
radiometry needed to be clarified. Also, the meaning of the IFOV will be different depending upon whether the beam is scanning
or not, and how the scanning takes place, e.g. ’continuous scanning’ vs ’stare-and-step scan.’ From this one term alone, it is clear
that more subtle meanings must be spell out in detail and a ’standard’ definition would help in understanding and comparing systems
and data in the literature. A selected list of terms with their suggested definitions will be discussed in this presentation.
