AVHRR stands for Advanced Very High Resolution Radiometer. It is a satellite sensor developed by the National Oceanic and Atmospheric Administration (NOAA) in collaboration with the National Aeronautics and Space Administration (NASA). The AVHRR is designed to capture and analyze data related to Earth's atmosphere, oceans, and land surfaces.
The AVHRR sensor operates in the visible, infrared, and thermal infrared wavelengths. It captures images of the Earth's surface by measuring the reflected sunlight and emitted thermal radiation. This data is essential in developing and maintaining a comprehensive understanding of our planet's climate, weather patterns, and overall environmental changes.
The AVHRR system collects data on various parameters, including sea surface temperature, vegetation cover, cloud cover, and snow and ice extent. It provides valuable information about climate change, drought monitoring, ocean currents, and environmental assessment for areas prone to natural disasters.
The AVHRR sensor is carried on multiple polar-orbiting satellites, ensuring global coverage and allowing for long-term observations. Its high spatial resolution, wide spectral range, and high temporal resolution make it a valuable tool for researchers, meteorologists, and policymakers.
In summary, the AVHRR is an advanced satellite sensor that captures data related to Earth's atmosphere, oceans, and land surfaces. It provides crucial information about climate change, weather patterns, and environmental monitoring, helping scientists and policymakers make informed decisions to better understand and protect our planet.
