Wavelet Compression of AVHRR Imagery
Fractals, 1997A compression tool for satellite based imagery of the earth's land and atmosphere is presented. Orthogonal wavelet filters are adopted for this purpose. The ability of the technique to compress images has been applied to AVHRR images of cloud fields and the earth's surface.

Precise AVHRR image navigation
IEEE Transactions on Geoscience and Remote Sensing, 1994A new AVHRR image navigation software package has been developed. Both direct and indirect image navigation capabilities are provided. An approach is used in which the orbital motion model for the satellite is an independent module. The attitude of the spacecraft is also modeled and the capability to estimate the attitude from ground control points is ...

Atmospheric transmittances for the AVHRR channels
Applied Optics, 1989Vertical path atmospheric transmittances from the surface to the top of the atmosphere have been computed for the five channels of the Advanced Very High Resolution Radiometer (AVHRR). Gaseous absorption computed from a line-by-line transmittance model and both molecular and aerosol scattering are included.

Compression experiments with AVHRR data
[1991] Proceedings. Data Compression Conference, 2002This paper describes several data compression approaches for producing browse data from AVHRR data, and evaluates these approaches qualitatively and quantitatively. They include a hierarchical data compression scheme based on progressively finer image segmentations, and various vector quantization approaches.

Remote Sensing of Environment, 1989
Abstract During 1988 the movement of a flood down the Darling River in central eastern Australia was monitored using AVHRR imagery. During the observation period the thermal channels at night gave better contrast between the flood and the surrounding land than the visible and near infrared channels during the day. The slow movement of the flood front

Monitoring the AVHRR calibration
Proceedings of IGARSS '93 - IEEE International Geoscience and Remote Sensing Symposium, 2002Over the years growing consideration has been given to the use of remote sensing data to absolute calibration problems and gain drift monitoring. Although most of the satellites have on-board calibration devices, their use, especially in then shortwave bands, remains difficult because of their uncontrolled ageing. In order to solve such a problem, some

Compression of AVHRR images by wavelet packets
Environmental Modelling & Software, 2000AVHRR is an imager flying on polar meteorological satellites that, due to its spatial resolution (about 1 km at Nadir view), produces a huge amount of data. A method based on the wavelet packet transform is devised to compress AVHRR images. The method is driven by the compression error (application dependent), so that different types of images have the

Identification of fog with NOAA AVHRR images
IEEE Transactions on Geoscience and Remote Sensing, 1991The authors attempted to identify fog using image-processing data from the US National Oceanic and Atmospheric Administration (NOAA) Advanced Very High Resolution Radiometer (AVHRR). AVHRR sensors measure radiation at visible, near-infrared, and infrared wavelengths.

The navigation of AVHRR imagery
International Journal of Remote Sensing, 1988Abstract One of the difficulties encountered in dealing with AVHRR imagery is that of navigating the data with an acceptable degree of precision. This paper describesa method, based on satelliteephemeris, which allowsaccurately gridded hard copy images to be produced in an easily reproduceable manner.

Filtering cold outliers in SSTs retrieved from early AVHRRs for the second AVHRR GAC reanalysis
Ocean Sensing and Monitoring XIII, 2021Global long-term SST record is being created under the AVHRR GAC Reanalysis (RANs) project, by historical reprocessing 4 km data of the AVHRR/2 and /3 instruments flown onboard multiple NOAA satellites from 1981 – present. The AVHRR data are reprocessed with the NOAA Advanced Clear-Sky Processor for Oceans (ACSPO) system.
