This swath width is able to provide complete coverage of Earth across the day. NASA Near Real-Time Data and Imagery Products. VIIRS Overview. In September, 2020 surpassed 2019 to become the most active fire year in the southern Amazon since 2012, the year that the VIIRS sensor was launched on the Suomi-NPP satellite. The Visible Infrared Imaging Radiometer Suite (VIIRS) sensor was launched aboard the Suomi National Polar-orbiting Partnership (NPP) satellite on October 28th, 2011 and on January 18th, 2012 cooler doors for the thermal sensor were opened. The NASA Suomi-NPP VIIRS Active Fire product suite builds on the MODIS Fire and Thermal Anomalies algorithm (MOD14/MYD14), systematically mapping global fire activity at ≤12 h intervals (~1:30am/pm local overpass times). The Visible Infrared Imaging Radiometer Suite (VIIRS) sensor on the Suomi National Polar‐orbiting Partnership (S‐NPP) satellite incorporates fire‐sensitive channels, including a dual‐gain high‐saturation temperature 4 µm channel, enabling active fire detection and characterization. The NOAA/NASA Visible Infrared Imaging Radiometer Suite (VIIRS) was launched onboard the S-NPP polar satellite on October/2011, followed by NOAA-20 - the first of the Joint Polar Satellite System (JPSS) series - on November/2017. The VIIRS instrument on NOAA-20 and Suomi-NPP provides high-precision locations of hot spots that help to detect fires earlier and determine their location and spread more precisely. After a brief lull, a late-September heat wave reinvigorated California’s already brutal 2020 fire season. Fire Data in Google Earth. SNPP VIIRS Fire and Smoke Imagery. ... voice: (801) 975-3737 fax: (801) 975-3478 MODIS VIIRS AVHRR GOES. The Visible Infrared Imaging Radiometer Suite (VIIRS) on the NOAA-20 satellite captured this natural-color image of the state on October 1, 2020. Such thermal anomalies are exploited by fire detection algorithms to determine whether a particular pixel observed by the satellite’s sensor is or is not associated with a forest fire.If a particular pixel is flagged to be a fire, it is indicated as a hotspot. This includes the M7, M8, and M10 spectral bands. With sunlight eliminated, combustion sources are readily detected, particularly in the M10 and M11 bands. Latest Detected Fire Activity. Using VIIRS for Mapping Wildfires Once VIIRS became part of Living Atlas, its users showed us that there are many ways this layer can be leveraged, but by far the most popular so far has been to track the wildfires that happened in the western United States over the 2020 summer. Land fires on the ground emit spectral signals that are characterised by higher emissions of mid-infrared radiation. The Fire and Smoke Initiative has helped improve the use of satellite fire and aerosol products to see and predict fire spread, air quality, visibility challenges due to smoke, and fire forecasts. The VIIRS active fire products complements the MODIS active fire detection and provides an improved spatial resolution, as compared to MODIS. Satellite active fire data We used VIIRS 375 m active fire data that has been successfully used to detect wildfires in different geographic regions (Schroeder et al., 2014). If no fires are detected for a given pass, a file is not placed on the server. The VIIRS instrument can collect data in 22 different spectral bands of the electromagnetic spectrum, in … Initially, these estimates were produced from DMSP (Defense Compared to other coarser resolution (≥1 km) satellite fire detection products, the VIIRS 375 m data provide greater response over fires of relatively small area, as well as improved mapping of large fire perimeters. Fire Detection GIS Data. Fire-detection satellites and perimeters SATELLITES Fire Perimeters GOES-16 Satellite GOES-17 Satellite MODIS Satellite VIIRS Satellite GOES and VIIRS may differ in fire location due to differing spatial resolutions and satellite parallax effects between the 2 satellite platforms. NOAA’s VIIRS active fire product development has been done through collaboration between STAR, the University of Maryland and the NASA VIIRS Land Science Team. VIIRS Active Fire Detection Data. The volume of smoke coming from the fires has been high in recent days and has spread across much of the state. The spatial resolution of the active fire detection pixel for VIIRS is 375 m. Additionally, VIIRS is able to detect smaller fires and can help delineate perimeters of ongoing large fires. VIIRS is based on a sensor that builds on the heritage of MODIS, with a markedly smaller pixel 'footprint' (375 meters for VIIRS, 1km for MODIS). A time-matched comparison of Shortwave Infrared images from Suomi NPP VIIRS (3.74 µm) and GOES-16 ABI (3.9 µm), valid at 0839 UTC on 22 October, is shown below. A second VIIRS sensor is flown aboard the NOAA-20 satellite (formerly JPSS-1), launched November 18, 2017. The SNPP VIIRS fire and smoke products are currently distributed to operational users including air quality forecasters through the IDEA (Infusing satellite Data into Environmental Applications) website that includes products generated from Direct Broadcast (DB data). VIIRS-AF (~750 m). Called VIIRS active fires, the new product is able to map fires at 375m resolution, which will make a significant difference in locating fires within the peatlands and forests of Indonesia and around the world. This data layer displays VIIRS (Visible/Infrared Imager/Radiometer Suite) satellite I-band fire detection data. The finer spatial resolution of VIIRS (375 meters at nadir, vs 2 km for ABI) provided a more accurate depiction of the location of hottest fire pixels at that time. clouds, fog, aerosols, fire, smoke plumes, dust, vegetation health, phytoplankton abundance and chlorophyll. So far this year, the VIIRS instrument on Suomi-NPP has detected 574,000 active fires, compared with 509,000 for … eIDEA shows the Suomi National Polar-orbiting Partnership (SNNP) Visible Infrared Imaging Radiometer Suite (VIIRS) smoke mask in shades of pink (light pink for thin smoke and bright pink for thick smoke; see scale on the top) overlaid on the true color image (also called as RGB for Red Green Blue wavelengths). Fire Detections - MODIS (1km), VIIRS (375m and 750m), AVHRR (1km) and GOES (4km) fire detections by time/date of occurrence within the last 6, 12 and 24 hours, and the 6 … By January 19, 2012, the sensor acquired its first measurements of fires. Satellite Imagery. VIIRS was launched on October 28, 2011, on the National Polar-orbiting Operational Environmental Satellite System Preparatory Project (NPP) satellite and produced its first image on November 21. The Fire Information for Resource Management System (FIRMS) distributes Near Real-Time (NRT) active fire data within 3 hours of satellite observation from the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Aqua and Terra satellites, and the Visible Infrared Imaging Radiometer Suite (VIIRS) aboard S-NPP and NOAA 20 (formally known as JPSS-1). VIIRS is unique in the recording of near-infrared and short-wave infrared data at night. The Moderate Resolution Imaging Spectroradiometer (MODIS) sensor onboard NASA’s Terra and Aqua satellites has been used to scan the Earth’s surface for fires on a daily basis for almost 15 years. Consequently, the data are well suited for use in support of fire … The algorithm to detect both day and night time fires and other thermal anomalies is based on the MODIS Fire and Thermal Anomalies product (Schroeder et al., 2014). Following an average start of the season, several wildfires broke out during mid-to-late August/early September including three of the top four largest wildfires on record for that state. Two VIIRS active fire products are generated independently using the available 750 m and 375 m resolution data. Satellite (VIIRS) Thermal... Satellite (VIIRS) Thermal Hotspots and Fire Activity 7680c8c0-fee9-45ec-bce9-d9f589ec0ece Satellite (VIIRS) Thermal Hotspots and Fire Activity Fire pixels represent the approximate location of a fire and do not represent the actual fire size. VIIRS features daily multi-band imaging capabilities to support the acquisition of high-resolution atmospheric imagery and other Nighttime M11 data became available in December 2017. Thick smoke plumes from those wildfires have impacted large areas across California as … The NOAA JPSS Active Fires Team is led by Ivan Csiszar at the NOAA NESDIS Center for Satellite Applications and Research (STAR). Hot Spot: The MODIS and VIIRS thermal layers are created from the MODIS satellite detection system and represents hot spots that could be potential fire locations in the last 24 hour period at a horizontal resolution of 1 km and temporal resolution of 1 to 2 days. At present, the VIIRS active fire product simply indicates the pixels with hot source detection. VIIRS detecting a forest fire in Wyoming, United States (courtesy NASA) Since several years ago, satellites have been used to detect fires. VIIRS scans the Earth twice-daily and is able to both detect smaller fires and map fires in greater detail. VIIRS has a swath width of 3060 km at the satellite's average altitude of 829 km. The counts of residue burning can be mapped from satellite remote sensing, fire event data. The inquiry that led to Nightfire arose from a project to improve the quality of natural gas flaring estimates from satellite data sources. In addition, the improved NPP Data Exploitation (NDE) algorithm delivers an improved fire mask and fire radiative power retrievals (FRP). Near real‐time SNPP VIIRS fire event data (i.e., VNP14IMGTDL_NRT) was acquired. The VIIRS instantaneous field of view at nadir is 0.75 km, but the fire phenomena may be much smaller than that.
