The issue here is whether use of a passive surveillance technology (a thermal imager in this case) is intrusive enough to amount to a search under the Fourth Amendment. The district court had concluded that the crude and limited nature of the imagery obtained meant that it did not show the kind of activities for which Kyllo had a legitimate expectation of privacy. 

From these and other data it follows that accuracy in the estimate of radiation balance as a function of space coordinates depends on cloud distribution, their state, and atmospheric pollution, as well as on the chosen size of pixels for spatial averaging. In this connection, Henderson and Chylek (2005) used image data from the Multispectral Thermal Imager to evaluate the effect of spatial resolution on aerosol optical depth retrieval from satellite imagery. It was shown that aerosol optical depth (AOD) depends weakly on pixel size in the range 40 x 80 m2 to 2,040 x 4,080 m2 in the absence of clouds and changes monotonically with the growing size of pixels in clouds. 

Figure 6. Scotian Shelf and slope-water region. The mean position of a thermal front with surface temperatures of -- 9-11 °C was contoured from satellite imagery and partly from Batfish profiling. The work area for Batfish transects is shown along 63°25 W (10).

Examination of individual frames of thermal and video imagery reveals details of disruption processes. Individual bubbles produce local warming, indicating some disturbance of the surface microlayer, but only partial renewal of the surface. A plume of bubbles acts in concert to produce rapid surface renewal within a well-defined area of the surface. The area affected by the plume expands well beyond the region where bubbles are surfacing.

For Figure 6.18a, image subtraction equates to the visible bubbles. For Figure 6.18b, this analysis shows the initial thermal distortions at an intermediate time and the bubbles at the end of pressurization. For the GHe case (Figure 6.18a), the imagery at bubble...
