Skylab/EREP Monthly Report for the Month of June, 1973
Project N SR397 Contract it NAS 9-13301
Activities during the month of June, 1973 were concerneu with
the coordination of surface observation and aircraft data acquisi-
tion activities in conjunction with the SL-2 overpass of one of
ry	 mcv the subject projects test sites. Preliminary indications indicate
-31 	 Ie that an excellent set of data were obtained during this reporting
period.
(A) Overall Status
IMn
	
	
A data set of potentially high quality was obtained by the
Skylab space station over a previously identified test site on
June 10, 1973. At the time of the Skylab overpass a field
f	 w spectroradiometer system that had been prepared by the Labo•atory
I	 o was in position on the Salt Creek boat ramp of Lake Monroe i,i
•	 Monroe County, Indiana, one of the test sites identified in the
I` r .Ii u subject project. Nearby the field spectroradiometer an instru-
z W u mertation station acquired solar and meteorological data several
hours before and after the overpass of the Skylab. A C-47 aircraft
n H z o	 operated by ERIM equipped with the M-7 multispectral scanner and1:14H u	 supporting photographic equipment overflew the Lake Monroe test
r-4 ,w	 site within a few minutes of the overpass of the Skylab, and approx-
^ w 	 imately two hours later the same test site was overflown by the
II H 04 11	 RB-57 aircraft operated by NASA at an altitude of 60,000 ft.
CI o on	 ApI.oximately 24 hours earlier the test site was in the field of
as=	 vitN of the ERTS satellite thus producing a multi-level data set
M w	 acquired in very close time proximity. In addition to the objectives
U ^	 out .fined in the subject proposal, it appears as though a detailed1 W 01`3
	
ser. or comparison study is now possible with this unique data set.
1004 	 W athe •r conditions were excellent in the vicinity of the test site

'—'0	 and assuming that all instruments were functioning properly, a
In o o data set of extremely high quality is expected.

Monthly Report
June, 1973
will be generated from the surface meteorological observations
that were made during the clay of the overpass. The Skylab data
is not expected to be available during the next reporting period,
but it is possible that the data from the ERTS overpass will be
available at the end of the next reporting period. If this be
the case, preliminary analysis of this data set will take place.
(D) Results
No significant results are reported since the data for analysis
is not yet available during this reporting period.
(E) Travel Summary and Plans
Travel to the Monroe Reservoir test site in order toset up
the surface observation systems was made during the month of June,
1973. In addition, a post-flight visit to the test site was made
in order to reconfirm surface observations made during the June
lOt;i overflight. Photographic documentation of each setup point
in the test site area was detailed.
