Virtual NDRC Webinar Series
The NASA Direct Readout Conference (NDRC) Organizing Committee is pleased to announce the second in a series of webinars to facilitate communications among, and provide updates to, the Real-time (RT) and Near Real-time (NRT) remote sensing user communities. Technology updates to be presented at this second webinar include:
- NASA VIIRS Level-1 Software/Algorithm (NASA);
- Processing of Suomi-NPP VIIRS Data for Near Real-Time Applications: Observations on VFIRE375 Active Fire Products (ISRO/NRSC); and
- NASA Black Marble (NASA).
The Ninth International NASA Direct Readout Conference (NDRC-9) held in Valladolid, Spain in June 2016 provided a venue for awareness and exchange of remote sensing science research and corresponding RT/NRT applications using Direct Readout and other low latency Earth observation capabilities. A key outcome of the conference was the need to facilitate forums for ongoing communications among RT/NRT data practitioners, organizations that enable decision support system operations, and the end user community. Click here to download the minutes of the first webinar held on May 29, 2018.
The webinar series will focus on NDRC-9 themes, topics and priorities, including updates on relevant science, algorithms, technologies, applications and systems The frequency and topics of webinars in this series will be based on input articulated by interested participants. Webinars will initially concentrate on Land discipline applications and broader topics, but may be expanded to include Atmosphere and Ocean disciplines. Presentations, action items, and relevant meeting notes will be published on the NASA DRL Web Portal.
Second Webinar and Agenda Details

Time: 11:00 a.m. Eastern Daylight Time (15:00 UTC)
Purpose/Objectives of the Webinar Series – Brad Quayle (USDA FS GTAC)
Purpose and objectives of this effort related to NDRC, and relevant updates.
NASA VIIRS Level-1 Software/Algorithm – Fred Patt (NASA OBPG)
A presentation of the NASA VIIRS Level-1 software and algorithm development effort was given at the 2016 NASA Direct Readout Conference. Since then two releases of the software have been completed, with features to enhance the VIIRS data products and support NOAA-20 (previously JPSS-1) VIIRS processing. The software is operational at all three NASA Science Investigator-led Processing Systems (SIPS), and is available in both the NASA DRL International Planetary Processing Package (IPOPP) and the Ocean Biology Processing Group's (OBPG) SeaDAS packages.
Processing of Suomi-NPP VIIRS Data for Near Real-Time Applications: Observations on VFIRE375 Active Fire Products
– Yugandhar Reddy S, TR Kiran chand, V.Pradeep, D.Shanmukha Rao, Gopalakrishnan Rajashekar, KV Chandrasekhar, AVV Prasad ,and CS Jha (ISRO/NRSC)
The National Remote Sensing Centre (NRSC) is one of the centres of the Indian Space Research Organisation (ISRO). NRSC is responsible for remote sensing satellite data acquisition and processing, data products generation and dissemination, development of remote sensing applications using satellite data, aerial remote sensing, and decision support for disaster management. NRSC has a state of the art ground station, the Integrated Multi-mission Ground Segment for Earth Observation Satellites (IMGEOS) at Shadnagar near Hyderabad, India. The IMGEOS infrastructure facilitates data acquisition and processing for a suite of Indian Remote Sensing (IRS) satellites as well as for different foreign satellite sensors such as MODIS (on-board Terra and Aqua), VIIRS (on-board S-NPP and NOAA-20) and the Landsat missions.
The active fire products are currently generated at IMGEOS using Science Processing Algorithms (SPAs) provided by the NASA DRL to process MODIS and VIIRS data. The present set-up for the fire production and dissemination system is a totally automated chain, wherein active fire alert information (satellite pass-wise) in the form of shapefiles and text files are sent to the user departments within 1 hour of Loss Of Signal (LOS). The information is also web-published through ISRO's geo-visualization web portal, Bhuvan
. The main stakeholders/users are national and state bodies governed by the Ministry of Environment, Forests and Climate Change, India.
This presentation focuses on the process and challenges involved in generating VIIRS 375m active fire products, and our observations/evaluation of the products. Topics include the potential of S-NPP VIIRS 375m data for identifying smaller and cooler fires in the Indian region; spurious fires generated by VFIRE375_SPA v2.5.1; and evaluation and advantages of the latest VFIRE375_SPA v3.0.0 provided by the DRL over the previous version in terms of removal of false detections, data compatibility (e.g., use of netCDF products instead of C-SDR products) and relevant issues.
NASA Black Marble Update
– Brad Quayle on behalf of Dr. Miguel Roman (USRA EfSI)
A brief update presentation on the current status of NASA Black Marble
production activities using S-NPP VIIRS DNB data and its application as part of the NASA Disasters Program in assessing impacts and recovery from disaster events. Additional information will also be provided about upcoming NASA-sponsored training on Black Marble scheduled to occur in early 2019 via the NASA Applied Remote Sensing Training (ARSET) Program.
