SEQ CHAPTER \h \r 1RAMM BRANCH WEEKLY HIGHLIGHTS FOR THE WEEK ENDING January 7, 2015IN THE PRESS: Nothing to ReportITEMS FOR THE ADMINISTRATOR:ITEMS FOR THE ASSISTANT ADMINISTRATOR:ITEMS FOR THE OFFICE DIRECTOR, STAR:ITEMS FOR THE DIRECTOR, CoRP:VISIT Satellite Chat: C. Seaman led a VISIT satellite chat on 18 December 2015 entitled “Introduction to NCC in AWIPS.” On 14 December, VIIRS DNB NCC imagery made its debut on AWIPS-2. In order to generate interest and answer questions on the product, a VISIT satellite chat was held to discuss this new imagery. There were 6 NWS WFO’s in attendance. A recorded version of this session may be viewed at: (C. Seaman, D. Bikos, B. Connell, E. Szoke, CIRA, 970-491-8446, Curtis.Seaman@colostate.edu, Dan.Bikos@colostate.edu, Bernie.Connell@colostate.edu, Edward.J.Szoke@)VIIRS Imagery Team manuscript for Remote Sensing now published: A manuscript by the VIIRS Imagery Team produced for a special issue of Remote Sensing (open access journal) has now been published. See . The manuscript features many operational uses of VIIRS Imagery as a major part of the post-launch checkout and continuing/ongoing validation of VIIRS. Title is “User Validation of VIIRS Satellite Imagery,” and authors are: Don Hillger, Tom Kopp, Curtis Seaman, Steven Miller, Dan Lindsey, Eric Stevens, Jeremy Solbrig, William Straka III, Melissa Kreller, Arunas Kuciauskas, and Amanda Terborg.

Hillger reviewed a third cal/val manuscript for Remote Sensing. (D. Hillger, E/RA1, 970-491-8446, Don.Hillger@)Manuscript Reviewed: K. Musgrave reviewed a manuscript for Asia-Pacific Journal of Atmospheric Sciences. (K. Musgrave, CIRA, 970-491-8446, Kate.Musgrave@colostate.edu)Manuscripts Reviewed: C. Seaman reviewed two manuscripts submitted to the Journal of Applied Meteorology and Climatology. (C. Seaman, CIRA, 970-491-8446, Curtis.Seaman@colostate.edu) Development of the improved algorithm for displaying VIIRS TC DNB imagery: As part of JPSS-TC project, work has begun on the development of the improved algorithm for VIIRS TC DNB imagery. Selected VIIRS data for the years 2012-2014 have been reprocessed, and the development of the database of the raw VIIRS TC DNB imagery has begun. Available images were split into several categories such as “blurry”, ‘too dark’, ‘too bright’, ‘city lights,’ ‘uneven illumination’, ‘moon glint’, ‘good images’, etc. Further, different ways of scaling DNB images for each of the above categories will be tested in order to create the best way to scale images for each of the above categories. Figure 4 shows an example of a VIIRS DNB image close to the new moon, which also has a lot of city lights. The combination of very little illumination and significant amount of city lights confuses the current simple scaling algorithm and, even though the TC is present in the data, it does not show up on the image produced by the automated algorithm, but is clearly seen on the image with manually adjusted scaling.

Left: image with automated scaling. TC is not visible because the scaling is wrong due to the presence of large amount of city lights and the time of the image close to the new moon. Right: manual scaling of the same image, showing that TC is present in the data and can be seen with the proper scaling.VIIRS NCC Imagery Archive at RAMMB/CIRA: AWIPS2 VIIRS NCC imagery is being archived at RAMMB/CIRA. The archive is useful in illustrating NCC utility at various phases of the moon, and will be utilized in development of additional NWS training. Imagery from the night of the December full moon has been provided to Harry Cikanek, NOAA Director for the Joint Polar Satellite System (JPSS), for use at the upcoming AMS annual meeting. (D.

Bikos led a VISIT teletraining session titled “Synthetic Imagery in Forecasting Cyclogenesis” on 7 January 2016. There were 7 participants from 2 NWS WFO’s in attendance. (D. Bikos, CIRA, D. Lindsey, E/RA1, 970-491-8446, Dan.Bikos@colostate.edu, Dan.Lindsey@)New VIIRS Imagery Team Blog post: The VIIRS Imagery and Visualization Team Blog has been updated with a new post titled, “The Great Flood of 2015.” This post discusses the flood event that impacted the U.S. Midwest during the holiday season, causing the Mississippi River to reach its highest crest since the Great Flood of 1993. St. Louis, MO received 3 month’s worth of precipitation in a three day period from 26-28 December 2015. Natural Color RGB imagery from VIIRS revealed flooding along rivers in Illinois, Indiana, Missouri, Arkansas, Kentucky and Tennessee. An example is shown in the figure below. This example was also provided for the JPSS “Image of the Month”. Images like these have been shared on social media. Additional images and discussion are available at: (C.
