HCW products were not received i n  Austral l a  u n t i l  ear ly 1979, and 
not i n  substantial quanti t ies un t i  1 m id -1979yhe  products as received 
are circulated to the several investigators. 
The investigators have continued various ground t r u th  prograrmnes on 
a sporadic basis. During the l i fe t ime o f  H C M  as number of "days o f  
interest"  were nominated to project  management, and the observation sched- 
u le  received from NASA indicates that  data were obtained on many o f  these 
days. However hard copy has not been received from some of these days yet. 
The majori ty o f  the investigators p1 an t o  use the data i n  CCT form 
fo r  the i r  detai led investigations. No useable CCTs have been received as 
yet. Consequently the majori ty of investigations, to date, have been o f  a 
prel  i m i  nary nature . 
A substantial number o f  tapes have now been ordered and analysis w i l l  
proceed i n  a more effective manner once they are received.

Division o f  Land Resources Management 
The investigation in to  the applications o f  HCMM image data t o  the 
management of a r id  land resources has so f a r  been l im i ted  t o  a perusal o f  
the circulated f i l m  products. However several interest ing observations 
have been made. The f i r s t  i s  that  OBI day I R  imagery i t  i s  possible t o  
dist inguish property boundaries, w i l d  f i r e  scars and, i n  one case, a state 
border. Checking t h i s  image against the v i s ib le  wavelength imagery and 
known ground s i tes reveals that  the comnon basis i s  a change i n  the amount 
o f  vegetative cover across these boundaries. These changes i n  vegetation 
re f lec t  i n  the f i r s t  case overgrazing, and i n  the la t te r ,  differences 
i n  the amount o f  overgrazing resul t ing from differences i n  land tenure

Dfvfston of Land Use Research 
Continuous records o f  surface and canopy temperatures have been 
obtained a t  Cowra throughout southen winter 1979. Surface s o i l  ,water 
and meteorological data are also available f o r  other s i tes  nominated 
by us. We have d ig i t i sed  images o f  Me1 bourne d i s t r i c t  and o f  Canberra- 
Cowra for a prel  iminary c l  imatological analysis. This prel  iminary work 
complete, progress depends en t i re l y  upon the receipt o f  the CCT data. 
Division of Fisheries and Oceanography 
This Division has used HCMM imagery t o  amplement ocean c i rcu l  at ion 
studies i n  Australian waters tha t  have previously been hampered by a lack 
o f  synoptic data. A bet ter  understanding o f  the east Australian current 
system has resulted from combining HCMM and other satel 1 i te imagery wi th 
the resul ts f rom ships and s a t e l l i t e  tracked buoys. Certainly the sate- 
11 i t e  imagery has high1 ighted the d i f f i c u l t y  o f  contouring sea surface 
temperature data from ships and has revealed the complex interact ion 
between warm east Australian current waters and eddies.
