Paper Abstract

Natural bodies of water have several advantages as IR calibration targets in remote sensing. Among these are availability, homogeneity, and accurate knowledge of emissivity. A portable, low-cost, floating apparatus is described for calibration of remote IR sensors to within 0.15 C. The apparatus measures the surface and bulk water temperature as well as the wind speed, direction, temperature, and relative humidity. The apparatus collects data automatically and can be deployed for up to 24 hours. The sources of uncertainty, including the effects of skin temperature and waves are discussed. Data from several field campaigns to calibrate IR bands of DOE's Multi-Spectral Thermal Imager are described along with estimates of error.
