Trends and uncertainties in thermal calibration of AVHRR radiometers onboard NOAA-9 to NOAA-16

[1] Satellite measurements from the infrared (IR) channels of the Advanced Very High Resolution Radiometer (AVHRR)/NOAA have been used to derive many important atmospheric, cloud, and surface parameters for weather prediction, climate modelling, and a variety of environmental studies. Calibration accuracy of the satellite data directly affects accuracies of the derived parameters. So far, very ...

Monitoring Burnt Areas in Portugal Using NOAA/AVHRR Imagery

The summer season of 2003 in Continental Portugal was by far the worst in what respects both to the number of forest fires and the amount of burnt area. In the present work, burnt area monitoring was performed using NOAA/AVHRR imagery by means of a neuro-fuzzy (ANFIS) algorithm that was applied on an operational basis to the surface of the country. Validation of obtained results was performed b...

Automatic Noaa Avhrr Image Registration in Mountains Area

This article presents a new and novel approach to accomplish AVHRR data navigation with errors of less than 0.9 km in the middle latitude regions. The AVHRR channel 4 counts and GTOPO30 elevation data and image correlation method are used. This approach is suitable for both day and night passes. It can also be used for other satellites with thermal sensing radiometers. A two steps approach is i...

Cross Comparison of Spot-4 Vegetation and Noaa-14 Avhrr

Spectral vegetation indices obtained from satellite sensors have been used to measure and monitor the Earth’s vegetative cover from local, regional, to global scales. The normalized difference vegetation index (NDVI) has been the most widely-used index and shown to correlate with green leaf area index, green biomass, and net primary productivity. The NDVI from the two sensors, National Oceanic ...

Fast Geometric Correction Algorithm of Noaa Avhrr Image

This paper presents a algorithm for the geometric correction of NOAA AVHRR data by using polynomial scan and pixel function. Preprocessings including tangent correction and earth curvature correction can be reduced the order of these functions. Using this method, it was possible to make the geometrically corrected image very fast. Also the precision of geometric correction is discussed.
