Description

Using remote sensing to estimate the spatial and temporal distribution of heat budget in geothermal and hydrothermal areas is yet to be acknowledged as a state of the art tool. The spatial and temporal distribution of the heat budget was estimated for Norris Geyser Basin (NGB), the hottest and most changeable thermal area in Yellowstone National Park. Airborne thermal infrared images in the 8-12 µm band along with multispectral images in the green (0.57 µm), red (0.65 µm), and near infrared (0.80 µm) bands, were obtained for five consecutive years with the intent of measuring the spatial distribution of surface temperatures and to identify the different types of terrain cover for the purpose of estimating surface emissivity. The images were taken in the month of September in each of the years under clear sky conditions, close to midnight and around midday. Consistent methods were used for image acquisition, processing, and atmospheric correction, to ensure that the variability in the results are solely due to variability in the geothermal system. The total heat budget comprising of conduction heat, convection heat, radiation heat, and mass transfer were estimated for NGB. High frequency real time data, needed to complete the estimation of the heat budget, were measured in two energy balance experiment towers installed upwind and downwind of the explosion crater within NGB. In this paper, information about image acquisition and processing, and the results of the heat budget during the five years are presented.
