Status of Misr Cloud-motion Wind Product
Near-simultaneous multi-angle imagery from the Multi-angle Imaging SpectroRadiometer (MISR) forms the basis of a unique method able to simultaneously retrieve cloud motion and height from a polar orbiter platform. The method is fully automated and determines the characteristic horizontal wind for a mesoscale domain of 70.4×70.4 km. Provided the co-registration of the multiangle views is accurat...
متن کاملAssigning Heights to Cloud Motion Vectors
Satellite derived cloud motion vector (CMV) production has been troubled by inaccurate height assignment of cloud tracers, especially in thin semi-transparent clouds. This paper presents the results of an intercomparison of operational height assignment techniques. Heights are assigned by one of three techniques when the appropriate spectral radiance measurements are available: the infrared win...
متن کاملGeometric Cloud Heights from Meteosat and Avhrr
Geometric cloud height estimation provides an alternative to cloud top temperature methods if two satellites view the same cloud. First we demonstrate the stereo cloud height derivation with a combination of Meteosat 7 and Meteosat 5 5 km resolution Infrared data. Comparison with the temperature technique shows consistency in the majority of the clouds, but some differences. This demonstrates t...
متن کاملMulti-view Cloud-top Height and Wind Retrieval with Photogrammetric Methods: Application to Meteosat-8 Hrv Observations
The height assignment of atmospheric motion vectors (AMV) is still an open issue. From the numerous height assignment techniques, each retrieval method has its own characteristics. The presented stereophotogrammetric method has the advantage that it is only dependent on the geometry and therefore offers a completely independent height retrieval compared to the other methods. As polar-orbiting i...
متن کاملComparison of cloud top heights derived from MISR stereo and MODIS CO 2 - slicing
The EOS-TERRA MODIS and MISR instruments provide radiances for independent spectral and stereo retrievals of cloud top height (CTH), respectively. Collocated and coincident CTH retrievals were compared against each other and with coincident millimeter-wave radar (MMCR) retrievals over the British Isles and the ARM SGP site. This intercomparison suggests close agreement between MMCRR, MODIS and ...
