Paniculate Data Reduction
(PADRE) System Reference
Manual
W.M. Yeager and C.E. Tatsch
The Particulate Data Reduction
(PADRE) system is an interactive
computer program that facilitates
entry, reduction, and analysis of cas-
cade impactor data for particle size
distributions. PADRE was developed to
ensure the quality of data included in
the Fine Particle Emissions Information
Systems (FPEIS), a component of the
Environmental Assessment Data Sys-
tems (EADS). Users control the logical
flow through the system in response to
prompts from the program. PADRE can
be used to store, review, edit, and
analyze data and, through a variety of
data checks, to identify invalid or
suspect data. Impactor stage cut points
are calculated, and cumulative and
differential mass concentrations are
determined and interpolated to standard
diameters. This document describes
how to access and use PADRE and
summarizes its logic and capabilities.
The program narrative describes all
calculations and algorithms and all
messages produced by the system.
Specific user instructions are detailed in
a separate PADRE User's Guide.
This Project Summary was developed
by EPA's Industrial Environmental
Research Laboratory. Research Triangle
Park. NC, to announce key findings of
the research project that is fully docu-
mented in a separate report of the same
title (see Project Report ordering
information at back).
Introduction
The purpose of the PADRE system is to
facilitate entry of validated cascade
impactor data from representative in-
stackruns into the Fine Particle Emissions
Information System (FPEIS). Reduction of
observed data, to determine the effective
stage cut diameters as well as the
cumulative and differential mass concen-
trations, takes only a few seconds; this
capability permits test plans or operating
conditions to be modified to optimize data
quality. Data entered through PADRE are
not automatically included in FPEIS; the
test contractor is expected to designate
representative runs after he has validated
the data.
Data Reduction is based on the Cascade
Impactor Data Reduction System (CIDRS)
computer programs developed by South-
ern Research Institute (SoRI) under
contract to EPA. PADRE allows data
reduction from a wider variety of impactor
types and configurations than does
CIDRS. Additionally, PADRE is interactive,
which facilitates data entry and allows
rapid analysis of impactor data by novice
computer users.
FPEIS was developed in the mid-
1970's and became fully operational in
January 1977. EPA's Industrial Environ-
mental Research Laboratory at Research
Triangle Park (IERL-RTP) then develped a
series of data bases (modeled on the
FPEIS concept) that would be capable of
reporting multimedia discharge informa-
tion uniformly and consistently. This
work resulted in EADS, which is both a
resource for producing evaluated infor-
mation and an environmental data
repository (see Figure 1). Its structure
permits full characterization of all data
with minimum redundancy.
Overview
Basically, the system consists of data
organization and data processing.
-------
Data Organization
Data organization and terminology are
as consistent with EADS/FPEIS as
possible. Thus, for PADRE, several
impactor runs (samples for EADS/FPEIS)
are logically connected to one test, with
specification of the stream and operating
levels embedded in the run data records.
In particular, all runs for a given test
share a common site and particle density
and begin on or after that test date. PADRE
utilizes user-specified keys (described
below) to access all stored data. Three
data categories may be entered by PADRE
users: weight data, test data, and run
data. A fourth category, impactor data,
must be supplied to the EPA Project
Officer before data can be reduced.
• Weight data include a description of
the substrates, pre-weights for each
substrate, and post-weights for each
substrate. Net weights are calculated
from pre-weights and post-weights.
Substrate pre-weights are entered
into the system independently of
run data. PADRE will assign a
substrate's ID number when the pre-
weights are first entered; users must
specify this ID number when they
enter run data.
• Test data are the same for all test
runs. These include the test com-
ments, (assumed) particle density,
site code, and test date.
• Run data include run comments,
operating conditions, identification
of impactor used, and ID number of
the set of substrates used in the
impactor.
• Impactor data include brand name,
model, serial number, calibration
date, and number of stages. For each
stage, the number of jets, average jet
diameter, Stokes' number, and
cumulative fractional pressure drop
are required.
Data are entered and stored in units
where they are commonly observed to
facilitate data entry and correction.
Data Processing
PADRE involves four processes: data
entry, data reduction, data comparison,
and data designation for inclusion in
FPEIS. In the entry process, observable
data are read from an interactive compu-
ter terminal operated by the user. These
data may then be reviewed and modified.
In the reduction process, effective cut
points (stage Dso's) and mass concentra-
tions for each impactor stage are com-
puted under actual operating conditions.
Mass concentrations are interpolated to
standard intervals. In the comparison

process, data from several user-specified
runs are reduced and statistics at each
standard diameter are computed. In the
designation process, observable data
from user-specified runs are printed in
the format of EADS data input forms. The
user may submit these forms to EPA to
include data in the EADS.
Prerequisites
Prerequisites of using PADRE include
EPA approval, data, and a terminal.
Approval of EPA
The PADRE system is operational at
EPA's National Computation Center
(NCC) on the UNIVAC 1100/83 computer.
The system may be made available to all
users of cascade impactors: EPA person-
nel, EPA contractors. State agencies, and
commercial and consultant impactor
users. EPA provides this resource tool to
analyze cascade impactor data with the
understanding that users will share
validated data from representative runs
by submitting them for inclusion in the
EADS/FPEIS data base.
Data
While new users are encourged initial-
ly to practice with PADRE using artificial
or sample data, it is assumed that most
users will be using actual data from in-
stack impactors. PADRE is no substitute
for a careful record of all operating
conditions and observed data. New users
may wish to transcribe these data to
PADRE data entry forms, as described in
the PADRE User's Guide. This procedure
will help users become familiar with the
variable names and brief descriptions
used in the prompts, prepare users for the
order of the prompts, and ensure that all
necessary data have been recorded.
Calibration constants for the user's
impactor are required in order to calcu-
late the Dso's. These may be submitted to
the EPA Project Officer before the PADRE
system is used, so they will be available to
the system when the impactor configura-
tion is specified. Calibration information
for a specific impactor is sought by the
impactor type (e.g., Anderson and Brink),
the impactor model (e.g., Mark III), and a
unique number assigned to the set of
plates used, in the calibration run. If a user
does not know the calibration constants
for his impactor but wants to conduct
preliminary analyses, he may specify the
impactor type and model with plate set ID
zero to access "generic" calibration
constants. The validity of the Dso's will, of
course, depend on how closely his
impactor corresponds to the mythical
impactor the generic calibration constants
describe.
Terminal
Access to PADRE requires an interac-
tive computer terminal. All program
printed lines contain less than 80 charac-
ters. Any terminal that can access that
NCC in Research Triangle Park, NC, may
be used, but one that produces a

TERMINATE SESSION
You can follow several paths thpouah this proaram. You will be offered
a series of options at decision points. At each decision point you
will be asKed a Question of the form "DO YOU WISH TO ...? ENTER Y OR N."
You may choose either to accept the option (e.a. enter data for a new run)
or to continue to the next decision point, where xou will be offered
another option. Indicate your decision by entering Y or NT then depres*
tne return Key on the terminal. Any response other than Y or N will be
rejected and you will asain be prompted to enter Y or N.
There are three basic sections or IOOPS. At the end of each section you
will have the option either to return to the beainnina of that section or
to proceed to the next section. After the last section, you will have the
option to return to the beainnina of the first section. There are no dead
ends in PADRE. If you take a wrona path, you can aluays drop throuah to
the bottom of the section, or of the proaram, and return to the beainnina.
When you indicate that you are ready to terminate the proaram, you will be asked
for comments about the proaram or its documentation. Please enter your comments
while your experience with PADRE is still fresh in your mind.

Once you've done the "00x tio," the data files are left in unpredictable
states of assianment in the system, so steps 2 ft 3 are necessary to reinitialize
everything.
Figure 2. PADRE introduction.
-------
permanent "hard copy" to document the
PADRE session is recommended. The
basic requirement is that the terminal
emulate a teletype at 30 or 120 characters
per second and handle computer com-
munications with even parity.
Use of PADRE
Use of PADRE includes user authoriza-
tion, logical control, data entry and
review, retrieving stored data, and
sample sessions.
User Authorization
Users should check with the EPA
Project Officer, Gary L Johnson, (9197
541-7612) to obtain the proper authoriza-
tion to access the EPA/NCC.
PADRE is readily availble to users
holding a valid NCC account number;
however, special arrangements may be
made for other users to access the NCC
(and PADRE) on a case-by-case basis
through the National Technical Informa-
tion Service (NTIS). All users will be
expected to bear the costs of the computer
use.
PADRE Logical Control
Users can follow several paths through
this program. For example, the user may
wish only to enter pre-weights for several
sets of substrates, or may wish either to
update or to reduce previously entered
data. The user will be offered a series of
options at decision points. At each
decision point, the user will be asked a
question of the form "DO YOU WISH
TO...? ENTER Y OR N." The user may
choose either to accept the option (e.g.,
enter data for a new run) or to continue to
the next decision point in the program,
where another option will be offered.
The user indicates a decision by entering
Y or N and then depressing the return key
on the terminal. Any response other than
Y or N will be rejected, and the user will
again be prompted to enter Y or N.
Figure 2 is a guide to the options this
program offers. There are three basic
sections or loops. At the end of each
section, the user has the option either to
return to the beginning of that section or
to proceed to the next section. After the
last section, the user has the option to
return to the beginning of the first
section.
No "dead ends" exist in PADRE. If the
user takes a wrong path, he can drop
through to the bottom of the section (or of
the program) and return to the beginning.
Data Entry and Review
Eventually, the user will reach a point
when he should enter observed data. The
computer will prompt him with a brief
description of and the name associated
with the data item. The computer will
then wait for the user to enter the data.
After all items have been entered, there
will be a review of the data, listing both
the names and values. The user will then
have an opportunity to mark which, if any,
items he wishes to change. After the
marked items have been changed, there
will be another review and opportunity to
make further changes. When the user
has been through the entire list of varia-
bles and has made no changes, the
system will proceed to the next decision
point.
Retrieving Stored Data
PADRE manages all data storage and
retrieval for the user, but certain user
requirements are basically matters of
good housekeeping. These requirements
are also essential for retrieving stored
data.
• Substrate weights are assigned an ID
by PADRE.
• Run data are saved by PADRE using
multiple keys.
To retrieve stored data, the user must
specifiy these keys exactly as originally
specified or assigned. Whenever PADRE
stores data, it prints a message with the
keys that must be used to retrieve those
data (see Figure 3). These keys should be
recorded for further reference.
If the user wants to recall data for an old
(previously entered) run, he must specify
the same site ID and test date as when the
data was originally entered, aswellasthe
run number assigned by PADRE. The user
will be prompted for each of these items
at the appropriate point in the session. If
the user wants to recall data from an old
test in order to modify the test data, he
must specify the same site ID and test
date as he did when the test data were
entered. He can then change any of the
test data; if any of the key items are
changed, the system will alter them for all
runs in that test.
Sample Sessions
Figures 3 through 5 show actual
PADRE dialog for basic operations. A pre-
viously entered set of data is modified and
reduced. Both the terminal and the
expanded output are reproduced.
