Geometric Cloud Heights from Meteosat and Avhrr
نویسندگان
چکیده
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 the stereo method as a verification tool for satellite cloud top temperature height retrievals. A case study of Meteosat plus AVHRR shows that the geometric technique can be extended beyond the range of overlapping geosynchronous observations. This uses an asynchronous stereo technique because the observations are not simultaneous.

A New Approach to Fog Detection Using Seviri and Modis Data
Meteosat 8 SEVIRI with its good spectral, spatial and temporal resolutions provides an excellent basis for the monitoring and nowcasting of fog. Based on this the present study outlines a method for fog detection using SEVIRI data, with algorithms for both, night and daytime. The night algorithm is ported from NOAA AVHRR and relies on brightness temperature differences between the 10.8 and 3.9 ...

A multispectral, multiresolution (MSMR) method is developed for analyzing scenes of overlapping cloud layers. The MSMR method is applied to data from the NOAA 11 advanced very high resolution radiometer (AVHRR) and the high-resolution infrared radiometer sounder (HIRS-2). The data are from a nighttime oceanic scene in which a semitransparent cirrus veil overlays a large-scale stratus cloud. Low...

This study reports on the first attempt to use cloud boundary and optical depth retrievals from the GLAS lidar to assess the accuracy of cloud-top heights obtained with MODIS (onboard NASA-TERRA and AQUA) and SEVIRI (onboard METEOSAT-8). Over the period from 25 September to 18 November 2003, MODIS-GLAS coincidences were only found in the Polar Regions, whilst SEVIRI-GLAS coincidences were avail...

The advent of the Meteosat Second Generation (MSG) provides many new opportunities for improved derivation of Atmospheric Motion Vectors (AMVs) from geostationary satellite data. MSG will provide full field of view imagery data every 15 min. with a sampling distance of 3 km, already improving the capabilities to derive AMVs. Another main improvement is the large range of available channels that...

Different methods have been proposed to detect multilayer clouds using passive remote sensing data. Baum et al. (1995) used the CO2-slicing technique applied to the High Resolution Infrared Radiation Sounder (HIRS) data to determine cirrus cloud heights. The spatial coherence technique (Coakley and Bretherton 1982) was applied to the advanced very high resolution radiometer (AVHRR) data to dete...
