Query: Estimation of Building Rooftop Temperature from High Spatial Resolution
  Aerial Thermal Images   This letter presents a novel technique to calculate temperatures of building
rooftops and other impervious surfaces from high spatial resolution aerial
thermal images. In this study, we collected aerial radiance images of 30cm
spatial resolution using a FLIR Phoenix imager in long-wave and mid-wave
infrared wavelengths for the city of Cedar Falls, USA to estimate building roof
temperature loss. Simultaneous ground temperature measurements were made at
pre-selected ground targets and roofs using 9 Fluke 561r infrared thermometers.
Atmospheric correction of aerial images was performed by Empirical Line
Calibration (ELC) method. The resulting ground-leaving radiances were corrected
for the emissivity of different roof types and the true kinetic temperature of
the building roofs was calculated. The ELC model was observed to perform better
when only impervious surface targets were used for the regression. With an
R2=0.71 for ELC, the method produced a root mean squared error of 0.74{\deg}C
for asphalt roofs. Further, we observed that the microclimate plays a
significant role while synchronizing aerial and ground measurements.
