2018年7月10日 · The Advanced Very High Resolution Radiometer (AVHRR) provides four- to six-band multispectral data from the NOAA polar-orbiting satellite series. There is fairly continuous global coverage since June 1979, with morning and afternoon acquisitions available. The resolution is 1.1 kilometer at nadir.

AVHRR is the backbone for the 1km global land cover product. We use global land cover to understand the human footprint on the land and its environmental impact. The AVHRR land cover product differentiates forest types, grass, shrub, cropland, and water.

2022年10月26日 · The Advanced Very High Resolution Radiometer (AVHRR) acquires measurements of land and sea surface temperature, cloud cover, snow and ice cover, soil moisture, and vegetation indices. Data are also used for volcanic eruption monitoring.

2018年7月9日 · The Advanced Very High Resolution Radiometer (AVHRR) is a broad-band, four or five channel (depending on the model) scanner, sensing in the visible, near-infrared, and thermal infrared portions of the electromagnetic spectrum.

Advanced Very High-Resolution Radiometer (AVHRR) is a space-based instrument that uses a single red-band spectral channel to estimate the amount of aerosols in the Earth's atmosphere, providing valuable data for aerosol research and modeling.

The Advanced Very High Resolution Radiometer (AVHRR) is a cross-track scanning system with five spectral bands having a resolution of 1.1 km and a frequency of earth scans twice per day (0230 and 1430 local solar time). There are three data types produced from the POES AVHRR.

NOAA CoastWatch / OceanWatch / PolarWatch produces Level 2/3 sea surface temperature datasets using AVHRR sensors aboard the Metop 1/2 satellites.

2021年2月1日 · Initially designed in the late 1970s to observe global cloud coverage, land characteristics, sea surface temperature, ice, and snow cover, the AVHRR is well known for its simple and robust design as a cross-track line-scanning radiometer.

2023年8月31日 · NASA's Level-1 and Atmosphere Archive and Distribution System Distributed Active Archive Center (LAADS DAAC) has released Version 6 of the Advanced Very High Resolution Radiometer (AVHRR) Long-Term Data Record (LTDR) Products. The products use data from eight AVHRR missions: MetOp-B, NOAA-19, NOAA-18, NOAA-16, NOAA-14, …

2024年12月1日 · How EODG Uses AVHRR. EODG uses AVHRR radiances as input to the Optimal Retrieval of Aerosol and Cloud (ORAC) algorithm. This code estimates aerosol, cloud and surface properties (depending upon the state of the atmosphere) which are used in both process and climatological studies.
