Automated atmospheric correction of AVHRR channel 1 and 2 data using dark surface targets
نویسنده
چکیده
A method is presented to allow for operational atmospheric correction of AVHRR channels 1 and 2 data. The method is based on radiative transfer calculations and subsequent application of Artificial Neural Network techniques. The method is applied to derive atmospherically corrected NDVI maps of the river Elbe catchment area in Central Europe.

Due to the effect of aerosols present in the atmosphere on the satellite images, the study of the effect of local aerosols distribution on the satellite images is important. On the other hand, the study shows that the effect of aerosols on the greenhouse gases and consequently on climate is also undeniable and as a result, this puts more emphasize on the necessity of this study. Lack of informa...

Methods for absolute calibration of visible and near-infrared sensors using ocean and cloud views have been developed and applied to channels 1 (red) and 2 (near-infrared) of the Advanced Very High Resolution Radiometer (AVHRR) for the NOAA-7. -9 and -I I satellites. The approach includes two steps. First step is intercalibration between channels 1 and 2 using high altitude (12 km and above) br...
متن کاملThe MODIS 2.1-μm channel-correlation with visible reflectance for use in remote sensing of aerosol
A new technique for remote sensing of aerosol over the land and for atmospheric correction of Earth imagery is developed. It is based on detection of dark surface targets in the blue and red channels, as in previous methods, but uses the 2.1m channel, instead of the 3.75 m for their detection. A 2.1m channel is present on ADEOS OCTS and GLI, and planned on EOS-MODIS and EOSP, and a similar 2.2m...

This paper explores the impact of the integrated water vapor content (IWV) in the atmospheric column on the corrections of optical satellite data over land. First, simulation runs were used to quantify the trends in red and near infrared parts of the electromagnetic spectrum. Second, advanced very high resolution radiometer (AVHRR) measurements obtained over Canada during the 1996 growing seaso...
