The NOAA/NESDIS Office of Research and Applications (ORA) has embarked on a pilot data stewardship project aimed at improving the data record from the Advanced Very High Resolution Radiometer (AVHRR). One part of this larger project includes the generation of a new cloud climatology from the Extended AVHRR Pathfinder Atmospheres (PATMOS-x) data set.

NOAA/AVHRR Bidirectional Reflectance
Remote Sensing of Environment, 1999Abstract In this article, bidirectional effects on NOAA/AVHRR short wavelength data were analyzed for the regional monitoring of the temperate pine ( Pinus pinaster ) Landes forest. Because of differences in soil hydrologic characteristics, the forest is described by five ecotypes, which determine the understorey type and the potential for pine ...

Multidimensional analysis method for NOAA AVHRR images
IEEE Transactions on Geoscience and Remote Sensing, 1994As a fundamental study of multiple image processing, the authors have developed a new technique for the analysis of multispectral remote sensing data. Though the basis of the authors' algorithm is similar to a histogram analysis, they have proposed a novel way of the representation of multidimensional image data, which facilitates a nonexpert to locate

Comparison of Turbidity Measurement by MODIS and AVHRR Images
2008 Fifth International Conference on Computer Graphics, Imaging and Visualisation, 2008The turbidity is commonly measured by turbidity meter. However, it is only accurate for single point measurement but ineffective for wide spatial and temporal coverage. The objective of this study was to calibrate the turbidity algorithm for AVHRR and MODIS images.

The ATOVS and AVHRR product processing facility of EPS
Advances in Space Research, 2005Abstract An overview on the Product Processing Facility (PPF) for the Advanced Very High Resolution Radiometer (AVHRR) and the Advanced TIROS Operational Vertical Sounder (ATOVS) instrument suite in the Core Ground Segment of the EUMETSAT Polar System (EPS) is presented. The PPF processing will include handling of instrument data from both, Metop and

Cloud Detection Using AVHRR Data
1996The split-window facility offered by the AVHRR instrument is used to good purpose in an advanced cloud detection and analysis package called APOLLO. This is based on threshold tests to distinguish between cloud-free, fully-cloudy and partially-cloudy pixels over land and sea surfaces.

An AVHRR mosaic image of Antarctica
International Journal of Remote Sensing, 1989Abstract This project was started in October 1985 with the objectives of (1) producing a 1 km-resolution database of Antarctica and (2) producing a 1:5 000000 scale image map. So far, 28 three-band AVHRR scenes have been corrected for variable Sun reflectance and transformed to a polar stereographic projection using a digitized coastline for control ...

Improving the AVHRR’s BRDF correction using MODIS
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019The Long Term Data Record (LTDR) has the goal of developing a quality and consistent AVHRR surface reflectance product using the MODIS instrument as a reference. When a surface reflectance time series is acquired from satellites with variable observation geometry, the directional variation generates an apparent noise which can be corrected by modeling ...

Evaluation of NOAA-AVHRR data for crop assessment
Applied Optics, 1982A study has been carried out in order to determine the angular limits which should be imposed upon NOAA06 and -7 satellite advanced very high-resolution radiometer (AVHRR) data used in vegetation assessment. The study involved simulations of anticipated sensor output over a wheat crop and empirical investigation of sensor data over vegetated areas. The

NOAA AVHRR workstation software
IEEE 1999 International Geoscience and Remote Sensing Symposium. IGARSS'99 (Cat. No.99CH36293), 2003A software package for carrying out the whole NOAA AVHRR data processing chain has been developed. This includes image data extraction, radiometric calibration and geometric corrections. The software supports three different raw file formats. Radiometric corrections include both atmospheric- and BRDF-conections.
