Abstract
The third Visible Infrared Imaging Radiometer Suite (VIIRS) was successfully launched on November 10, 2022, onboard the NOAA / NASA Joint Polar Satellite System (JPSS-2) satellite, which was later designated as NOAA- 21, after reaching its final orbit. Following a series of spacecraft and sensor activation operations, the VIIRS nadir door was opened on December 5, 2022.
VIIRS provides operational global imagery twice daily with moderate spatial resolution for a variety of environmental applications including fire, cloud, aerosol, vegetation, ocean color, and other geophysical parameters. VIIRS imagery is operationally used at Alaska national weather service for weather forecasting and event monitoring.The VIIRS Sensor Data Record (SDR) products include measurements in 22 spectral bands (along with their geolocation), covering the wavelength range from 0.4~12.5 μm. The VIIRS SDRs are used to provide the science & operational user communities with multiple high-quality Environmental Data Records (EDRs) that are essential for multiple operational applications and scientific research.
The instrument is currently undergoing an intensive Calibration/Validation (Cal/Val) phase to evaluate the instrument performance and ensure comparable SDR data quality to its predecessors, onboard the Suomi NPP and NOAA-20 satellites. In this talk, we present an overview of the various NOAA-21 VIIRS post launch test (PLT) activities, and initial assessment results of the VIIRS SDR (geometric & radiometric) product performance, conducted by the NOAA STAR team. Known anomalies and issues will also be discussed.
