For example, there are several differences in observation style, channel, structure, etc. from the Advanced Very High Resolution Radiometer (AVHRR) which flew on low earth orbit satellites since the 1970s. Several longstanding climate data records were developed expressly using the AVHRR instrument. The VIIRS Global Area Coverage (VGAC) dataset is an attempt to more closely bridge the old technology with the new. The VGAC data file provides one orbit of VIIRS observations (22 channels: 14 Reflective Solar Bands; 7 Thermal Emissive Bands and 1 Day/Night Band) that have been degraded in resolution to approximate the AVHRR GAC resolution. Each channel is provided using the same swath that simulates a 3.9 km resolution scan. The moderate resolution VIIRS channels each have the mean value of the radiance in that 3.9 km region. Some of the higher resolution imaging channels (I channels) contain more statistical information, including maximum and minimum radiances, which benefit algorithms like cloud and surface retrievals. The main purpose of VGAC data is to facilitate climate processing to continue the historic climate records from AVHRR and other satellites. onGoing NOAA National Centers for Environmental Information Customer Engagement Branch 1-828-271-4800 1-828-271-4876 151 Patton Avenue Veach-Baley Federal Building, Room 468 Asheville NC 28801-5001 USA ncei.orders@noaa.gov https://www.ncei.noaa.gov HTTPS Web Browser NOAA National Centers for Environmental Information (NCEI) NCEI home page with information, data access and contact information. information 8:00 - 6:00 Eastern pointOfContact asNeeded https://www.ncei.noaa.gov/pub/data/metadata/images/C01703.jpg Suomi NPP VGAC (M15) JPEG Earth Science > Spectral/Engineering > Visible Wavelengths > Visible Radiance Earth Science > Spectral/Engineering > Infrared Wavelengths > Infrared Radiance Earth Science > Atmosphere > Atmospheric Radiation > Reflectance theme Global Change Master Directory (GCMD) Theme Keywords 2018 revision Version 8.6 Global Change Data Center, Science and Exploration Directorate, Goddard Space Flight Center (GSFC) National Aeronautics and Space Administration (NASA) https://earthdata.nasa.gov/about/gcmd/global-change-master-directory-gcmd-keywords HTTPS Web Browser Global Change Master Directory (GCMD) Keywords The information provided on this page seeks to define how the GCMD Keywords are structured, used and accessed.
