Introduction


The JPL/HCMM Investigation is a study of the feasibility of using thermal


inertia, inferred from remotely sensed temperature data, to complement Landsat


reflectivity data for reconnaissance geologic mapping and mineral exploration.


During the January - March 1979 quarter of this investigation a detailed field


measurement program was carried out at the Death Valley, California test site.


Simulated and actual HCMM satellite data of the Pisgah Crater, California test


site were compared and found to be similar. The development and construction of


a device to measure thermal inertia in situ was begun in this quarter.


Problems


To date, only one set of satellite daytime data tapes has been received.


This lack of HCMH satellite data remains the major obstacle at this point in the


investigation. Until satellite data coincident with our field measurement


programs are made available, no significant conclusions concerning the HCMM


satellite data are possible.


Accomplishments


The investigation at Death Valley, California is designed to develop a


better understanding of the physics of the spatial and diurnal temperature


variations of this region and determine if these temperature patterns are


related to the hydrogeology of the region. A four-man field team began a


measurement program the week of February 12 - 16, 1979, to coincide with the 
February 15, 1979, HCMM overpass. Micro-meteorological measurements taken at


six sites in the Valley included, soil heatflux; net radiation flux, net


long-wave radiation flux, incident short-wave radiation flux; and windspeed,


temperature, and humidity at seven levels over an 8 m height interval. In


add~tion, surface radiation temperatures and subsurface probe temperatures


were measured at three sites. Soil moisture samples were collected at the


1.


subsurface probe levels at each site and at various depths along a prominent


alluvial valley.


It is assumed the HCMM satellite data coincident with this measurement


program was successfully acquired. Mechanical breakdown prohibitad


acquisition of Daedalus (U-2) thermal data.


A simulated HCMM satellite image of the Pisgah Crater test site had


previously been created from aircraft data obtained in March, 1975. This


image (figure 1) has been compared with an image created from a satellite


daytime data tape (figure 2) obtained during the May 31, 1978, HCMM overpass


of this same area. Each image appears to accurately portray the size and


shape of the Sunshine and Pisgah basalt flows and the playa, Lavic Lake. The


satellite data looks very similar to what was predicted by the aircraft


simulated data.


The development and construction of a field thermal inertia measuring


device was begun in this quarter. The device employs two standards of known


thermal inertia which will be simultaneoiusly and equally heated along with


the ground surface by quartz heating lamps. The ratio of the heating history


of either of the standards to the heating history of the ground surface can be


directly related to the ratio of the thermal inertia of the standards to


calculate the thermal inertia of the ground surface. After construction is


completed and laboratory testing defines the capabilities of the system, field


work with the device will be initiated.


Significant Results


Comparison of a simulated HCMM image of the Pisgah Crater, California


test site obtained from aircraft data with an image generated from the


preliminary satellite data tape of the area indicates that the HCMM satellite


data appears much as predicted by the simulation.

Program for next reporting interval


Analysis of previously obtained aircraft and ground-truth data will


continue. Analysis of satellite data will commence upon receipt of HCMM data


tapes. Laboratory testing of the thermal inertia measuring device will be


carried out and a detailed field sampling program will be initiated at the


Goldfield, Death Valley, and Pisgah Crater test sites.


Recommendations


It is recommended that the HCMM COTs be disseminated to the investigators


in some reasonable length of time after acquisition to allow them to proceed


with their studies.
