Assessing the performance of MODIS and VIIRS active fire products in the monitoring of wildfires: a case study in Turkey

Abstract

Biogeosciences and Forestry Biogeosciences and Forestry Assessing the performance of MODIS and VIIRS active fire products in the monitoring of wildfires: a case study in Turkey Kadir Alperen Coskuner MODIS and VIIRS fire products have been widely used to detect and monitor fire activity at a global scale, as they provide highly relevant information on fire events, on their spatial and seasonal trends. Although these products have some limitations in detecting fires in forested areas due to closed canopy and smoke, they have been widely used to monitor and assess forest fires in many scientific studies. This study analyzes the performance of MODIS (MCD14ML) and VIIRS S-NPP (VNP14IMG) active fire/hotspot products in fire detection in five different land cover types (closed and open forests, shrublands, herbaceous vegetation and croplands) and compares the results to the ground-based fire database from 2015 to end of the 2019 in Turkey. Detected fires with a confidence value above 30% (nominal and high confidence) were used in the study. The land cover was assessed using the European Space Agency (ESA) Copernicus Global Land Service (CGLS) Dynamic Land Cover Layers at 100 m resolution in the study area. The performance assessment of two fire/hotspot products were conducted in three fire size classes, namely: fire size <1 ha, 1 to 10 ha, and >10 ha in five different land cover types. The results indicated that the overall accuracy of MODIS ranged from 0.6% to 16.6% and VIIRS S-NPP ranged from 1.3% to 25.6% of all ground-based fires in five different land cover types. The detection rates increased as the fire size increased. This study indicates that some limitations still exist to use MODIS and VIIRS S-NPP active fire/hotspot data in the assessment of wildfires.

Assessing vulnerability of peat fire in the Indonesian Peat Hydrological Unit (PHU) areas

“…Hotspot data from two satellite image sensors are used for the hotspot analysis: the Visible Infrared Imaging Radiometer Suite (VIIRS) sensor on S-NPP and NOAA 20 (formerly known as JPSS-1) and the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor on Aqua and Terra satellites. In order to maximise the study of site attributes suggesting fire occurrences, this hotspot analysis makes use of multiple hotspot sensors [14]. The examination of 2023's fire hotspots is restricted to the months of January through June.…”

The Potential of Using SDGSAT-1 TIS Data to Identify Industrial Heat Sources in the Beijing–Tianjin–Hebei Region

“…Thermal infrared sensors can capture radiation energy differences caused by temperature variations, making them suitable for monitoring thermal emissions produced by industrial heat source production activities [17,18]. Several thermal infrared sensors, such as the Advanced Very High Resolution Radiometer (AVHRR), the Along Track Scanning Radiometer (ATSR) and Advanced ASTR (AATSR), the Visible and Infrared Scanner (VIRS), the Moderate Resolution Imaging Spectrometer (MODIS), the Visible Infrared Imaging Radiometer Suit (VIIRS), the Landsat 8/9 Thermal Infrared Sensor (TIRS), and the Sentinel-3 Sea and Land Surface Temperature Radiometer (SLSTR) [19][20][21][22], are available for generating heat-related products. These products are mostly used for identifying heat sources such as wildfires, agricultural burning, and volcanoes [23][24][25][26].…”
