Detección de incendios en México utilizando imágenes AVHRR (temporada 1998)

Investigaciones Geográficas, 1999
La temporada de incendios de 1998 en México fue excepcional. En ello contribuyeron los fenómenos meteorológicos del año anterior (huracanes y bajas temperaturas, principalmente) que ocasionaron la deposición de grandes cantidades de material ...

Impact of AVHRR Channel 3b Noise on Climate Data Records: Filtering Method Applied to the CM SAF CLARA-A2 Data Record

Remote Sensing, 2017
A method for reducing the impact of noise in the 3.7 micron spectral channel in climate data records derived from coarse resolution (4 km) global measurements from the Advanced Very High Resolution Radiometer (AVHRR) data is presented.

Shift Towards Syndiniales Prevalence in Protist Communities During a Marine Heatwave

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.
During a marine heatwave, protist diversity decreased and communities became more homogeneous. The parasitic dinoflagellate Syndiniales became the most dominant group in Subtropical Waters and the Southland Front. Since host‐parasitoid interactions are important in carbon and nutrient cycling, they should be considered when studying heatwave impacts on

Extending AVHRR Climate Data Records into the VIIRS Era for Polar Climate Research

Remote Sensing
The Advanced Very High-Resolution Radiometer (AVHRR) onboard NOAA-7 through NOAA-19 satellites has been the primary data source for two Climate Data Records (CDRs) that were developed specifically for Arctic and Antarctic studies: the AVHRR Polar ...

Warm, Productive Waters Shape the Habitat of Vocalizing Omura's Whales in Northwest Australia

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT Unlike most capital‐breeding baleen whales that migrate between feeding and breeding grounds, the Omura's whale mainly inhabits tropical waters year‐round. This study investigated the environmental predictors of Omura's whale acoustic presence off northwest Australia by opportunistically using existing archival acoustic recordings from 2005 to

Noise characteristics of the AVHRR infrared channels

International 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.

A global daily AVHRR true-color image record since 1981 derived from the XBAER-RGB reconstruction framework

International Journal of Digital Earth
True-color images synthesized from red, green, and blue (RGB) bands are essential for monitoring the Earth’s surface and atmosphere. However, the Advanced Very High-Resolution Radiometer (AVHRR), despite four decades of observations, lacks green and blue
