Luvall, J. C.; Holbo, H. R. 1989. Measurements of short-term thermal responses of coniferous forest canopies using thermal scanner data. Remote Sensing of Environment. 27: 1-10.
Thermal Infrared Multispectral Scanner. (TIMS)data were collected over the H. J. Andrews Experi-mental Forest, a coniferous forest in western Ore-gon. TIMS flights were timed to coincide with solarnoon. Flight lines were overlapped with a 28-mintime difference between flight lines. Concurrentradiosonde measurements of atmospheric profilesof air temperature and moisture provided inputs toLOWTRAN6 for atmospheric radiance correctionsof the TIMS data. Surface temperature differencesmeasured by the TIMS over time between flightlines were combined with surface radiative energybalance estimates to develop thermal responsenumbers (TRN). These numbers characterized thethermal response (kJ m- 2 °C —1)) of the differentsurface types. Barren surfaces had the lowest TRNwhereas the forested surfaces had the highest.
