SKYLAB/EREP MICROWAVE INS r nuMENT 5-193 
The University of Kansas, Center for Research, Inc. reports the following 
work performed during the period 1 August 1974 to 31 August 1974. 
1.0 CONTINUING STUDIES 
1.1 (Task 2.1.1.2, 2.1.3.1, 2.1.3.2) Development of Catalogue for Radio- 
meter Temperature Measurements Performed to Date. 
Work has begun again on compilation of the catalogue. Progress i s  
satisfactory. 
1.2 (Task 2.1.3.3) St~rdy of Effects of Atmosphere Upon S193 Rad/Scat Measurements. 
Further computations have been performed for ctmospheric effects on 
rneosurements made by the 5193 sensors. Particular effort for the month of August 
has been devoted to the of "best" input data to the program. For example, 
water content, ceiling and thickness of clouds have been obtained from recorded 
climatological data. The data derived i s  being applied to  the Texas Specific 
Site Studies (see 1.3-b below) to determine its relevance. Presently, two cloud 
conditions are being considered: thin clouds at 0.6 grarnr/'meter3 of water and 
3 heavy clouds at 1.0 grams/meter of water. 
1.3 (Task 2.1.1.5, 2.1.3.1, 2.1.3.2) Ground Truth Collection and Data Cata ogue . 
Ground truth collection and data cataloging have now evolved into a more 
systematic procedure, The progress that has been made i s  satisfactory and should 
now continue at a better pace. Some of the more noteworthy achievements are 
mentioned beiow. 
(a) Cataloging of the Data Base: 
$193 data received in tcpz form has t i l l  now only been dccornmutated on 
an "as needed" basis, but generally rest iic:ed to data being used for specific 
site studies or single pass, single mode analysis. I n  anticipation of the need for 
an expanded ~ 1 9 3  data base, effort has been d~rected toward decommutating a l l  
tape data and to provide it in forms (either magnetic tape or tabloid) suitable for 
use by a l l  :=::=&hers on the project. Init ia! c r f x t  has been directed toward 
decomming a l l  data within the continental United States. Data in these forms 
should experience a much wider usage among rne various tasks of this project. 
b). Specific Site Studies: 
Work on the specific site studies, Texas and Utah, i s  continuing with the 
intention of identifying the most relevant factors to be considered for analysis 
and cataloging of S- 193 data. 
Maps have been plotted for a l l  Skylab photography received for this project 
indicating i t s  spatial location and extent and the amount of cloud cover. Three 
categories of cloud covered have been indicated: less than 25 percent, 25 to 50 
percent, and greater than 50 percent. Th is  information i s  crit ical since the amount 
o f  cloud cover for the various passes i s  generally extensive. For example, for a l l  
photoaraphy received for SL-3, th i r tys ix  percent of i t  has greater t h n  50 ~ e r c o n t  
cloud cover. Sixty percent of the SL-3 photography has varying degrees of cloud 
cover, but less than 25 percent cover overall. As mentioned in 1.2 above, re- 
finements as to the effects of cloud cover on the data from the S- 193 instruments 
are being performed. Since the dynamic range of the values measured by both 
the radiometer and scattermeter over the Texas site i s  relatively small, the 
effects of cloud cover are even more significant. Considering that a 
majority of the passes being analyzed for the Catalogue have notable amounts of 
cloud ccver, this factor becmes even more relevant. Other factors that have 
been studied for their effects on 5-193 measurements have been soil moisture, 
ground tcmperature, topography and land use. 
Cloud free ERTS imagery has been received for the Utah Test site. Pre- 
liminary analysis indicates good correlation of 5-103 Rad/Scat data to the areal 
distribution of the Great Salt Lake Desert, the Salt Lake and Utah Lake. In- 
vestigations CIS to the factors causing the wid: :z:iations in measured signals are 
continuing and w i l l  include a coniparison of data from the SL-3 pass over the area 
to the 5?-2 p c ; ~  pi~;en:!y beii ib \?i ,~!,~ed. 
c). Computer Data Analysis: 
Histograms are being produced for varcous sets and subsets o i  the 5-193 
data. For eumnple, histograms of sets of data consisting of the radiometer and 
scatterometc: -easurements for one mode in c i-vticular pass are generated. 
Subset histograms within this context then might consist of the scatterometer and 
radiometer measurements obtained within particular ranges of incidence angles. 
Composite histograms are also being compiled for the various modes of 5-193 
operation in  addition to overall (all data takes) histograms for indications of 
expected dynamic ranges of the earth's scene when measured by the S-193 radio- 
meter and scotterometer. 
Computer analysis has also begun on identifying those portions of various 
posses within which the measured (both radiometer and scatterometer) scene appears 
homogeneous to the 5-193 instrument. This information i s  to be compared to that 
which i s  obtained by the studies discussed i n  1.3-d which follows, 
d). 5-1 93 Footprint Analysis: 
Cataloging of land use, climatological data and other relevant information 
on a "by footpririt" basis i s  continuins. Footprints within areas that are expected 
to exhibit a reasonable amount of homogeneity to the 5-193 instrument are being 
catalogued. Anomalies from the expected norm are being noted and given 
particular attention. I t  i s  expected that this method of data analysis w i l l  logically 
merge with the computer approach disc~ssed in 1.3-c above. 
e). Secondary Effect Corrections to S- 193 Radiometer/Scatterometer Signals. 
Efforts have continued on this task with reasonable satisfaction. Cross- 
polarization effects for the scattcrorneter have been modeled and work i s  now con- 
tinuing to extend this model to cover the effects on the radiometer also. 
2.0 REPORTS COMPLETED 
N o  rc-r~orts wer? completed this month. 
3.0 SPECIAL ANALYSES 
No special analyses were requested of us this month. 
4.0 DATA RECEIVED 
N o  data was received in August. 
5.0 COMMENT 
Because of cloud cover, i t  i s  anticipated that some diff iculty w i l l  be 
encountered in  obtaining land use information for our analysis. Concurrent 
Skylab photography was anticipated to be our primary source of land use 
information but now this appears to be too incomplete because of cloud cover. 
Thus, in this context, efforts are being made to obtain EFTS imugery for those 
Skylab pcsses where cloud cc\vcr i s  excessive. I t  i s  anticipated that the tirnc 
i t  tokes to receive such imagery may somewhat l imit  us on gathering of the 
necessary land use information.

SYLAB/EREP MICROWAVE I N3SUMENTS- 193
The University of Kansas, Center for Research, Inc. reports the following
work performed during the period 1 September 1974 to 30 September 1974.
1.0 CONTINUING STUDIES
1.1 (Task 2.1.1.2, 2.1.3.1, 2.1.3.2) Development of Catalogue for Radio-
meter Temperature Measurements Performed to Date.
This task was temporarily postponed due to excessive activity in the other
tasks.
1.2 (Task 2.1.3.3) Study of Effects of Atmosphere Upon S193 Rad/Scat Measure-
ments.
A standardized scheme to obtain climatological data in a form- satisfactory
for computation of atmospheric effects is presently being sought. The scheme that is
currently being used is adequate for present purposes but involves greater manpower
than is warranted. For example, daily temperatures(for. pertinent days and sites)
are obtained from monthly weather reports and punched by hand to feed into the
computer.
1.3 (Task 2.1.1.5, 2.1.3.1, 2.1.3.2) Ground. Truth Collection and Data Catalogue.
This comprises the brunt of the effort for this month.. Emphasis on system-
atizing the cataloging procedure has hampered the pace for the current period but
should greatly compensate for this slow pace in the very near future. Some of the
significant accomplishments are enumerated below.
a). Decommutz:!on of Data
Rather than decommutate data only on an 'as need' basis, the entire data-
base is being decommutated and put on one universal data format. This task is further
complicated by ie fact that data has to be screened prior to being, introduced into
the data-base to be used for this proJect.
b). Specific Site Studies
A significant amount of effort has been spent on specific site studies for
the two sites ui,,.r careful examination - Utah cnd Texas. Progress in these studies
is satisfactory. rreliminary findings will be reported next month.
c). Computer Data Analysis
Computations of general statistics including production of histograms of the
various sets and subsets of S-193 data are being performed.. Progress, is satisfactory.
d). S-193 Footpring Analysis
Cataloging of land use, climatological data and other relevant information on
a "by footprint" basis is continuing. This is a slow process but a certain amount of this
is essential to help interpret the computer aided analysis.
2.0 REPORTS COMPLETED
No reports were completed this month.
3.0 SPECIAL ANALYSES
No special analyses were requested of us this month.
4.0 DATA RECEIVED
No data was received in September.
5.0 COMMENT
We have been informed that NASA has reprocessed some SL2 S193 data.
We are awaiting receipt of this data with some concern, because of the subject
label having been tagged by NASA onto data received previously.

The University of Kansas Center for Research, Inc. reports the following
work perforleJu during the period 1 June 1974 io 30 June 1974.
1.0 CONTINUING STUDIES
1.1 (Task 2.1.1.2, 2.1.3.1, 2.1.3.2) Development of Catalogue for Radiometer
Temperature Measurements Performed to Date.
Satisfactory progress was made in compilation of this catalogue.
1.2 (Task 2.1.3.3) Study of Effects of Atmosphere Upon S193 Rad/Scat Measurements
Satisfactory progress was made in compilation of this report.
1.3 (Task 2.1.1.5, 2.1.3.1, 2.1.3.2) Ground Truth Collection and Data Catalog
The brunt of the effort is involved in preparing for a classification scheme
based upon either SKYLAB S193 data or upon supporting evidence (e.g. 5190
photographs, land-use maps, etc.). To this end, a specific-site study (initiated
earlier) has been advanced. This specific-site study is based upon three or four sites
for which the interpretation can be enhanced by the simplistic (e.g. one category
only).nature of the terrain or by virtue of additional ground truth information (e.g.
soil moisture samples); it should provide a guideline by which to classify the 5193
Rad/Scat data.
Statistical procedures are being applied to the S193 Rad/Scat data. For
example, h*-4'grams of distribution of the radiometeric temperature and differential
backscattering coefficient for each pass, polarization, incidence angle and mode
are being generated. These will be combined to form a composite histogram of
distribution fc;r each polarization and incidence angle as perceived by SKYLAB 5193.
Examples of some of the preliminary histograms for the distribution of the radiometeric
temperature are provided in Figures (1) through (5).
The ctaloging of the land-use type for enich footprint to be used for
correlation w;iil S193 data is being confined tV .:eas of near homogeneous terrain.
We feel this will allow for easier correlation with S193 data; later, this correlation
will be attempted on multiple category footprints.
