The altitude range is delimited by the first and
last measurement of the same elevation scan.
An elevation scan include all the measurements
made by varying the angle of the elevation
mirror while the azimuth mirror remains at a
fixed angle. See pointing 18.104.22.168. for more information.
The distance along-track
between two measurements at the same altitude.
remote sensing system, nadir refers to the point
on the ground located vertically below the
center of the system.
A nominal scan is a elevation scan that
acquired in nominal mode 22.214.171.124. . Other type
of scans are called "special event scans".
Special event scan:
Any scene measurement scan
that is not a nominal scan.
The point where the line
of sight of MIPAS intercept a line that is
perpendicular to the Earth geoid.
The distance between two
consecutive measurements in the same elevation scan.
The ZPD time is the UTC time
at the moment when there is no optical
path difference between the two mirrors of
the interferometer. It is used as reference
time for time tagging the sweeps and the scans.
