These day/night registered data consist of the following images: day visible, day thermal infrared, night thermal infrared, temperature difference (produced by differencing the radiometric temperatures observed during the night and day passes), and apparent thermal inertia. Each image is processed in an elongated format to provide maximum day/night overlap and may depict a scene as long as 3000 km. Each day/night pair is processed as a separate entity. (The quality of registration is scene dependent, being a function of the number and location of the features that can be identified and the residual distortion in the scene, caused by errors in estimation of the satellite attitude). Each frame contains a 16-step gray scale and annotation as to the date (day, month, year); latitude/longitude of the scene center; definition of the image type, i.e., day-vis, day-IR, etc.; sun angles (elevation and azimuth) where applicable; geometric correction applied to the data; type of ephemeris data used to compute the image center; agency and project names; and frame identification number. Data are available in black and white on 241-mm transparencies or prints.
