    On the design issues for a spaceborne rain mapping radar (1988)
    In:  Other Sources
    Details
    Publication Date: 2011-08-19
    Description: The design concept for the spaceborne rain mapping radar for the Tropical Rain Measuring Mission (TRMM) of Thiele (1987) is examined. The TRMM requirements for sampling strategy, spatial and height resolutions, observable altitude, and rain rate measurement range are described. The adaptive scanning and nadir Doppler measurement modes for the radar are discussed.

    Multicolor laser altimeter for barometric measurements over the ocean - Theoretical (1983)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: It is noted that the optical path length from a satellite to the earth's surface strongly depends on the atmospheric pressure along the propagation path. The theoretical basis of a surface pressure measurement technique, which uses a two-color laser altimeter to observe the change with wavelength in the optical path length from a satellite to the ocean surface, is evaluated. The statistical characteristics of the ocean-reflected pulses and the expected measurement accuracy are analyzed in terms of the altitude parameters. The results show that it is feasible to obtain a pressure accuracy of a few millibars.

    Rain-Mapping Radar (1988)
    In:  Other Sources
    Details
    Publication Date: 2019-07-12
    Description: Orbiting radar system measures rates of rainfall from 0.5 to 60 mm/h. Radar waves scattered and absorbed by rainfall to extents depending on wavelength, polarization, rate of rainfall, and distribution of sizes and shapes of raindrops. Backscattered radar signal as function of length of path through rain used to infer detailed information about rain. Accumulated radar return signals processed into global maps of monthly average rainfall for use in climatological studies.
