NOAA National Centers for Environmental Information (NCEI

We would like to show you a description here but the site won't allow us The Earth Observations Group (EOG) at NOAA/NCEI is producing daily mosaic images and monthly composites using nighttime data from the Visible Infrared Imaging Radiometer Suite (VIIRS) Day/Night Band (DNB). VIIRS DNB sensors are on the Suomi National Polar-orbiting Partnership (NPP) satellite and on the NOAA-20 satellite Figure 2-1. Processing flow of the VIIRS AST algorithm...15 Figure 2-2. Left: Global daily mosaics created using NOAA-20 (top) and S-NPP (middle) alone for January 1, 2020 have data gaps. Those gaps are filled when both satellites are used to create a combined daily mosaic (bottom) VIIRS Corrected Reflectance imagery is available only as NRT imagery. The imagery can be visualized in Worldview, GIBS and Rapid Response. The sensor resolution is 750m and 375m (M Bands are 750m, I Bands are 375m), imagery resolution is 250m, temporal resolution is daily and temporal availability for viewing in GIBS/Worldview is November 24.

VIIRS creates a daily global mosaic, a map of the entire planet in each filter. Kroeger grabbed all these maps for a year in the red, green, and blue filters (so he had 365 maps in each color). There are lots of options Kroeger had in putting them together to create a single map. Adding them all together to get a weird, smeary version of the. The first of two VIIRS DNB-based datasets is a daily, top-of-atmosphere, at-sensor nighttime radiance product called VIIRS/NPP Daily Gridded Day Night Band 15 arc-second Linear Lat Lon Grid Night.

MODIS products from Terra are available from February 2000 to present and Aqua products are available from June 2002 to present. They are available for daily, 4-day, 8-day, 16-day, and annual composite periods at 250-m, 500-m, or 1-km resolution, depending on the product. VIIRS products are available from January 2012 onward The VIIRS includes a Day Night Band (DNB) imaging capability which allows for high sensitivity imaging in low light conditions.

The global image mosaic software passed the code review in June, 2015 and the product passed the operational readiness review in October, 2015 As the world's water resources come under increasing tension due to dual stressors of climate change and population growth, accurate knowledge of water consumption through evapotranspiration (ET) over a range in spatial scales will be critical in developing adaptation strategies. Remote sensing methods for monitoring consumptive water use are becoming increasingly important, especially in.
