NOAA satellite observation in the Antarctic

open access: yesAntarctic Record, 1997
The NOAA Satellite AVHRR data received at Syowa Station offer simultaneous images on 5 wavelengths covering an area 2000km on a side with resolution of 1km, and are useful for helping to clarify a number of phenomena.

Retrieval of Coarse-Resolution Leaf Area Index over the Republic of Kazakhstan Using NOAA AVHRR Satellite Data and Ground Measurements

open access: yesRemote Sensing, 2012
A new multi-decade national-wide coarse-resolution data set of leaf area index (LAI) over the Republic of Kazakhstan has been developed based on data from the Advanced Very High Resolution Radiometer (AVHRR) and in situ measurements of vegetation ...

Restoration and reconstruction of AVHRR images

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 1995
Describes the design of small convolution kernels for the restoration and reconstruction of Advanced Very High Resolution Radiometer (AVHRR) images. The kernels are small enough to be implemented efficiently by convolution, yet effectively correct degradations and increase apparent resolution.

Use of high-resolution measurements for the retrieval of temperature and gas-concentration profiles from outgoing infrared spectra in the presence of cirrus clouds [PDF]

open access: yes, 2003
We explore ways in which high-spectral-resolution measurements can aid in the retrieval of atmospheric temperature and gas-concentration profiles from outgoing infrared spectra when optically thin cirrus clouds are present.

AVHRR and VISSR satellite instrument calibration results for both Cirrus and marine stratocumulus IFO periods [PDF]

open access: yes
Accurate characterizations of some cloud parameters are dependent upon the absolute accuracy of satellite radiance measurements. Visible wavelength measurements from both the AVHRR and VISSR instruments are often used to study cloud characteristics. Both

Sea ice - atmosphere interaction: Application of multispectral satellite data in polar surface energy flux estimates [PDF]

open access: yes
In the past six months, work has continued on energy flux sensitivity studies, ice surface temperature retrievals, corrections to Advanced Very High Resolution Radiometer (AVHRR) thermal infrared data, modelling of cloud fraction retrievals, and ...

Operational generation of AVHRR-based cloud products for Europe and the Arctic at EUMETSAT's Satellite Application Facility on Climate Monitoring (CM-SAF) [PDF]

open access: yesAdvances in Science and Research, 2009
The Satelite Application Facility on Climate Monitoring has implemented a new processing environment for AVHRR-based climate monitoring products. AVHRR measurements from NOAA-17, NOAA-18 and MetOp-A are utilized to generate daily and monthly means of ...

Noise characteristics of the AVHRR infrared channels

open access: yesInternational Journal of Remote Sensing, 1989
Abstract Limitations on the precision of digitized data are identified and discussed. Apart from calibration errors, these sources of uncertainty can be divided into three types of noise; digitization, Gaussian and periodic, each of which behaves differently when data is averaged.
