Identification of fog with NOAA AVHRR images

IEEE Transactions on Geoscience and Remote Sensing, 1991
The 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.

Compression of AVHRR images by wavelet packets

Environmental Modelling & Software, 2000
AVHRR 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

The navigation of AVHRR imagery

International Journal of Remote Sensing, 1988
Abstract 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, 2021
Global 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.

NOAA AVHRR image referencing

International Journal of Remote Sensing, 1986
Abstract A simple and fast algorithm for image referencing of the NOAA (National Oceanic and Atmospheric Administration) AVHRR (Advanced Very High Resolution Radiometer) data has been derived to facilitate the identification of geographic co-ordinates corresponding to any pixel on an NOAA image and vice versa.

Operational AVHRR navigation results

International Journal of Remote Sensing, 2000
A navigation method that combine a precise image deformation model and an automatic adjustment on coastal landmarks is operationally used at the CMS on AVHRR imagery. This paper presents the principles of the method, the error sources and a detailed analysis of the results obtained in 1996-1997 with NOAA-14 and NOAA-12 images.

Automatic Adjustment of AVHRR Navigation

Journal of Atmospheric and Oceanic Technology, 1992
Abstract An automatic adjustment method of the Advanced Very High-Resolution Radiometer (AVHRR) images navigation has been developed for operational use at the Centre de Meteorologic Spatiale (CMS) in Lannion, France. Selected coastal landmarks are correlated with small windows of an actual AVHRR image using visible and near-infrared channels 1 and 2 ...

Intercalibration of AVHRR and ATSR data

Advances in Space Research, 1996
Abstract The characterization of the AVHRR and ATSR instrument's relative performances and the intercalibration of their data products has been carried out. The intercalibration of two different infrared sensors shall be planned as an operational exercise in the future with automatic software tools.

Navigation of coastal AVHRR images

International Journal of Remote Sensing, 1992
Abstract This paper describes a simple, computationally inexpensive procedure for automatically identifying coastal features in an unnotified, unregistered daytime image. The procedure can be used to identify ground control points for image registration and to provide a local correction for the navigation predicted from the satellite orbit parameters ...

Calibration of the NOAA 10 AVHRR

Remote Sensing of Environment, 1988
Information supplied to me concerning the calibration of the NOAA 10 AVHRR (Price, 1988) was faulty. As with the preceding instruments, the NOAA 10 equivalent albedo coefficients were based on Thekaekara's values of the solar constant. The corrected values for Table 1 are, for Channel 1: Equivalent Solar Radiance = 499., a = .528, 13 = - 17.6, and for ...
