Scientific Approach

VIIRS products (current and under development) in orange

44

Goal(s): Demonstrate VIIRS near real time image products via the web that

covers the globe, includes Google Earth viewing Provide global perspective that enables users to zoom in and view

mesoscale weather Convert existing algorithms from VIIRS heritage sensors (MODIS,

AVHRR, OLS) Advertise VIIRS capabilities globally , sending JPSS imagery of current

interest Augment VIIRS organic products with LEO and GEO derived products

and VIIRS EDRs (chlorophyll & NCC) Store 22 days (~17 TB) of VIIRS data with a product production with a

daily production of ~52,000 images Satellite sensors: VIIRS, GEO (6), LEO (24 currently)

Targeted NOAA users: NWS, NOAA Fisheries, Proving Ground activities

Period of Performance: September 2012 – June 2015 Budget: $328,000

Overview

Key Accomplishments Through collaborative efforts, provided near real time output to VIIRS products

– 15-45 minutes from Direct Readout sites at CIMSS and NRL-Stennis– 1-3 hours via the AFWA IDPS/FNMOC portal

Leveraging the lunar irradiance model developed at CIRA– producing and hosting variety of quantitative nighttime products using Day/Night Band

Transitioned several MODIS algorithms to VIIRS on NexSat and VIIRS webpages during FY2014

– Contrails (Figure 1)– Dust (Figure 2)– Near Constant Contrast (NCC) EDR (Figure 3)

Publications during CY13/14– NexSat in BAMS “Nowcast”: “Next-generation satellite meteorology technology unveiled”

(December issue, 2013)– Other CIRA/NRL publications (in preparation, in review, accepted): 13 (avail upon request)

Collaborated with COMET in the production of two VIIRS-related training modules

Presented JPSS Science Seminar (Dec. ‘13) featuring NexSat with follow-on JPSS feature article

Provided extensive support to the greater Caribbean region with NexSat customized products and training – NRL received official letter of appreciation from Puerto Rico MIC– Through NexSat, NRL staff provided extensive VIIRS and MODIS

product/monitoring support to NWS during flooding, degraded air quality conditions, and TC events

– VIIRS applications products: imager channels, dust, true color, nighttime surveillance via DNB

User statistics– Average of 300,000 web hits per day during 2013– NexSat products are at times the only source of available satellite

information throughout the Caribbean NexSat demonstration capabilities

– Operational and in near real time since its inception in 2004 NexSat support of 12 missions involving training and customized

products toward scientific field campaigns during 2013/2014 – SEACR4S, DeepWave, J. Dunion (SAL), Marines training, TW13,

CoCoRaHS, NWS (SFO and San Juan), Beaufort Sea, TAPS, Lake Victoria, NOAA Fisheries

Issues

Please note– Variable NexSat funding limits effective planning while

minimizing contract efforts, namely from CIRA– Irregular delays in receiving global near real-time VIIRS digital

data– DOD travel restrictions have limited conference participation

99

Complete the transition of selected MODIS algorithms into VIIRS. Included in the list:– Fire detection– AOD – Binary cloud/snow & multi-cloud/snow

Develop over water AOD product to monitor nighttime dust over NW African using VIIRS DNB with lunar irradiance model

Develop VIIRS fire products for day and nighttime monitoring

Develop sea ice monitoring over various Arctic regions Apply ancillary imagery using upcoming Himawari-8 data Pending DOD approvals, present NexSat results at

conferences

Schedule for Remainder of Project

1010

Provide quantitative assessments of dust products Provide better discrimination techniques between sea

ice and low clouds in the Arctic Integrate VIIRS with upcoming ABI-like datasets from

Himawari-8 (2014), GOES-R (2016), and Meteosat Third Generation satellites (2018)

Integrate GPM’s microwave imager (GMI) and dual frequency precipitation radar (DPR) into NexSat and NRL-VIIRS product suite

Continue satellite training via a variety of outlets: social media, Webinars, military operators
