DESIGN DATA COLLECTION WITH
SKYLAB/tREP MICROWAVE INSTRUMENT S-193
The University of Kansas Center for Research, Inc. reports the
following work performed during the period. 1March 1974 to 31 March 1974.
1.0 CONTINUING STUDIES
1.1 (fask 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 catalogue.
1.3 (Task 2.1.1.5) Ground Truth Collection
Data for all U. S. continental passes received by the University of Kansas
Center for Research, Inc. is being decommutated from the original packed format
on computer compatible tape (As per TR-543) to a listing for qualitative
examination and reformated for computational facility. Qualitative correlations
with ground truth are being performed by plotting selected sample footprints on
maps and examining the land-use. S-190 Photographs, so far, have been our
main source of discriminating/identifying land use and/or meteorological conditions.
1.4 Data Analysis
The analysis of S-193 data proceeds on tenterhooks. The problems with
the production data processing algorithms have been understood and care is taken
during processing to ignore data points with obvious anomalies. The major problem
with the data received is that one does not know if one has accurate data (spatial
location or microwave response).
Quite often the 5-193 microwave response indicates a certain type of target, while
the spatial location listed is quite the contrary. As an example consider the follow-
ing. The radiometer temperature dropped sharply to that of a water body;* the
center of field of view indicated, however, was not close enough to a water body.
The only water body shown on the map was Lake Flathead (Montana) which was about
9' due east of the footprint and considerably closer to other footprints which did not
register a low radiometric temperature.
The anomalies observed in the computer-compatible tapes have already been
identified to the various NASA organizations and a copy of these anomalies is
included here. These are the obvious anomalies and do not include the subtle ones
found by a detailed analysis of data.
2.0 REPORTS COMPLETED
There were no reports completed this month.
3.0 SPECIAL ANALYSES
There were no special analyses requested of us. We are still awaiting a
decision regarding the reprocessing of data.
4.0 DATA RECEIVED
As per telephone call with Mr. Larry York, we have decided to use all
data received at the University of Kansas for the purposes of designing a data
catalogue.
