(A) Tbe range corrected con-
tour 'or the 5,25, and 45
dbz lote08H)' levell are shown
for. Une of echoes In the
northern seelor 01 Muddy
Road IV. In thl. example the
mulmum Intensity core 20
mUelI north of the radar sHe
hu a rellecUvlly 01 52 db.
as shown by the computer
drawn cuneI' (loUd Une).

A PPI can be acquired in
about 20 lIoe. Au additional
20 ne. are required to dill-
play the range normaUr:ed
and contoured radar echoes
on the Tektronlx 4010 CRT
display unll. Any PPI
lelecled for Ilorage on the
computer disk pack can be
Instantly played back. or
they can be retuned for uee
In later analysis.

(b) While seeding opera-
Uons are in progreu there
may be a need for I closer,
detailed look at the IItruclurtl
of a particular echo. In thle
example the Intenae cell 20
mi. norlh of the radar slle
was aelected for closer
study. An expanded, oft~
set display Ihus Klvea the
seeding director a detailed
view of the PPI profile of
the cell.

During laler analyala there
may alao be a need for
detailed dlsplsys. Thos.
can be generated from the
dIgitally stored radar data,
wllh the analyst eelectlng
any portion of the IItored
PPI for study. The selec-
ted cell or porUon of the
PPI IIcan can be off-set and
dleplayed at any scale and
at any contour interval.
