A technique of construction of detailed atmospheric TPW fi elds (resolution of 0.2°) from satellite microwave scan- ners is proposed. Application of this technique to SSM/I measurements for the period of 07/28 – 08/26, year 2000 in conjunction with the previously proposed by the authors method of satellite maps space-time interpolation allowed to build animated TPW map of the global coverage with spatial sampling of 0.2° and time step of 1.5 hour. Achieved parameters correspond to the best animated products claimed in the world literature, and are critical to the analysis of fast energy-intensive processes in the Earth’s atmosphere. An advantage of the authors’ technique is the closed computational scheme in regards with the incoming satellite information, and minimum model assumptions (generic model of motion estimation/compensation).
Keywords: SSM/I, интегральное паросодержание, пространственно-временная интерполяция, SSM/I, total precipitable water, spatiotemporal interpolation
