The Along Track Scanning Radiometer (ATSR) is a planned ERS-1 payload for accurate sea-surface temperature measurements under two different incidence angles from a conical scan.Abstract:
The Along-Track Scanning Radiometer (ATSR) is a planned ERS-1 payload for accurate sea-surface temperature measurements under two different incidence angles from a conical scan. It is investigated whether it can additionally be used for cloud stereoscopy and wind determinations as proposed by DFVLR for the Stereo Line Scanner (SLS). Although not designed for these types of measurements the ATSR seems very useful for a pilot experiment with only a lower resolution than proposed for the SLS. Because of distortions that occur with the conical scan of the ATSR, synthetic stereo imaging with additional height corrections is recommended instead of direct stereoscopy. Quantitative cloud heights can be derived from parallax measurements. Estimations of the influence of the pixel size and the alignment changes lead to cloud-height accuracies of up to ±750m. The influence of cloud motion on the parallax may be corrected with cloud-motion vectors derived from geosynchronous satellite data. An experiment for...read more

Cloud height determination by satellite stereography.
TL;DR: A feasibility study of deriving cloud height was conducted by the use of two geosynchronous meteorological satellites (GMS-1 and GMS-2) as discussed by the authors, where it was found that it is possible to obtain the fine structure of cloud in a relative accuracy of 200 m, but a large number of dependable reference points around the target cloud are required as well as the precise orbit parameters, to obtain a high accuracy of absolute cloud height.
