Dr. Christopher Elvidge of NOAA/Mines' Payne Inst. presents "VIIRS Data Gems from the Nights" on Fri 8/23 at 3pm in CH 143
The NASA/NOAA Visible Infrared Imaging Radiometer Suite (VIIRS) was designed primarily to meet the observational requirements of meteorologists. VIIRS are flown in 100 minute polar orbits and collect image data with a 3000 km swath. A complete set of daytime and nighttime images are collected every 24 hours. The VIIRS is similar to several other satellite sensors but is unique in the collection of low light imaging data in five spectral bands. The best known of these is the day / night band (DNB), which is designed to image clouds at night in the visible range. The other four low light imaging bands are daytime channels in the near-infrared and shortwave infrared. The Earth Observation Group has developed three global data product lines based on nighttime VIIRS data: nighttime lights (VNL), boat detections (VBD), and nightfire (VNF). The seminar will provide an overview of the three product lines and projects that are using the data.
