Incorporating Sentinel-1 SAR imagery with the MODIS MCD64A1 burned area product to improve burn date estimates and reduce burn date uncertainty in wildland fire mapping

Abstract: Wildland fires result in a unique signal detectable by multispectral remote sensing and synthetic aperture radar (SAR). However, in many regions, such as Southeast Asia, persistent cloud cover and aerosols temporarily obstruct multispectral satellite observations of burned area, including the MODIS MCD64A1 Burned Area Product (BAP). Multiple days between cloud free pre-and postburn MODIS observations result in burn date uncertainty. We incorporate cloud-penetrating, C-band SAR-with the MODIS MCD64A1 BAP in Sou… Show more

“…[13] applied Bayes' Theorem approach [14] to combine potential BA detections from Landsat-8 OLI, Sentinel-2 MSI and MODIS instruments to delineate the BA and monitor the progress of the 2017 Elephant Hill fire in California. One of the most recent studies by [15], combined Sentinel-1 SAR imagery with a monthly averaged MODIS BA product to reduce the burn date uncertainty of the MODIS BA product caused by observations obscured by clouds. Significant decrease in backscatter between two SAR images was used to detect BA affected pixels in SAR images which allowed to decrease the burning date uncertainty.…”

“…The IOP Publishing doi:10.1088/1755-1315/1061/1/012013 2 delineation of burned areas using only radar images may be difficult or limited for some landscapes, since the radar signal reflected from the burned surface may be similar in intensity to the signal from other components of the landscape (for example, areas of open ground) or be associated with other processes (logging, flooding, etc.) [13]. Therefore, the optimal solution is often the joint use of radar images and optical range images to delineate burned areas and analyze their recovery rates [10,11,[13][14][15][16].…”

“…[13]. Therefore, the optimal solution is often the joint use of radar images and optical range images to delineate burned areas and analyze their recovery rates [10,11,[13][14][15][16]. Another interesting methodological approach is the joint use of radar images in different polarizations (usually C and L) to monitor vegetation restoration in burning areas [17][18][19][20].…”

“…In the works [Rasul, et al, 2021;Ertugrul, et al, 2019;Lasko, 2019], the authors determine the dynamics of increasing the large burned areas of forest over certain periods of time using remote sensing data from the resource MCD64A1 500m. The main factors causing the increase of fires in the studied regions are analyzed.…”
