Radiative transfer modeling of thermal infrared emissivity spectra: applications to martian regolith observations
… of planetary regolith surfaces, in the form of thermal infrared emissivity spectra taken at nadir and off-nadir angles of emergence from the surface, requires use of theoretical models for interpretation of constituent grain physical properties. However, such models have remained in stasis in …

Classification of infiltration characteristics of depressions in landfill covers using uncalibrated, thermal-infrared imagery
Landfill covers are intended to promote runoff and prevent water infiltration into the wastes. Water infiltrating through an earthen cover can mix with the wastes causing an undesirable increase in the amount of leachate and methane generated by decomposition. A common failure of the design is the …

Thermal Infrared Imaging for the Charity Hospital Cemetery Archaeological Survey: Implications for Further Geological Applications
Recent work by Bob Melia of Real Time Thermal Imaging L.L.C. suggests thermal infrared (TIR) imaging can be used to identify subsurface archaeological features buried as deep as 3 meters but the basis for his work has not been tested. In November of 2002, Bob Melia and I attempted to locate …

Effect of halite and calcite coatings on thermal infrared spectra wih implications for Mars exploration
… for attaining this knowledge because the thermal infrared (TIR) remote sensing method for determining mineral abundance is limited to the top few hundred micrometers of the surface. To better understand the TIR properties of salt coatings, we investigated the effects of coating thickness …

Thermal-infrared radiosity and heat-diffusion model for estimating sub-pixel radiant temperatures over the course of a day
… have a single emissivity spectrum and are isothermal. Thus, estimated temperatures and emissivities are the effective values that would be found if these simplified assumptions were met. In reality, the physical scene is neither homogeneous nor isothermal, and the effective values are not …

Investigation of skin temperature differentials in relation to estrus and ovulation in sows using a thermal infrared scanning technique
… during the periovulatory period using digital infrared thermography (IRT), which has already been successfully used as a therapeutic and diagnostic tool in various fields and species in veterinary medicine. The experimental group consisted of a total of 25 gilts and 27 multiparous sows, and a …

Development of a Special Purpose End-to-End Satellite Constellation Design Methodology
… better ground sampling precision over existing thermal infrared platforms for the monitoring of thermal emissions over a target area. Our special purpose framework is robust, modular, and fast, allowing it to serve as an effective reference point for any commercial, scientific, and governmental …

The hydrography and dynamics of rings and eddies of the Agulhas retroflection February-March 1987
… are analyzed in conjunction with satellite data (Thermal Infrared Imagery and Geosat Altimetry). An unusual and possibly atypical situation is documented where a total of six Agulhas rings and eddies were present in the Retroflection region. Each of the six vortices exhibited characteristics …

Toward reliable localization: exploring infrared fiducial markers and multi-imu fusion as alternative sensor modalities
… explores two alternative sensor modalities: infrared fiducial markers and multi-IMU integration, as means to enhance localization robustness in GNSS- and vision-degraded settings. Vision-based navigation systems, which commonly rely on visible-spectrum cameras and fiducial markers (e.g., …

The Usefulness of Ground Penetrating Radar in locating burials in Charity Hospital Cemetery, New Orleans
… the property ground penetrating radar (GPR) and thermal infrared (TIR) data were collected in the cemetery to locate unmarked graves. The TIR data could not be used because the expert died before compiling the TIR data. Therefore, the GPR data was the sole source of subsurface information. GPR …

Risk mapping of eMalahleni municipal area with focus on coal mining impacts
… and for environmental risk management. Aerial thermal infrared spectrometry is a technique which can be used to detect coal fires. The technique produces thermal infrared images which can be mosaicked in a GIS program and classified to indicate the localities of coal fires. Subsidence can be …

Investigating patterns in stream temperature and restorable alluvial water storage for climate resilience of freshwater habitat for salmon and trout
… made use of available data derived from airborne thermal infrared imagery to identify spatial patterns of stream temperature in the Teanaway River watershed in Washington, USA and compared these patterns to modeled predictions of restorable alluvial water storage. By investigating patterns in …
