A new, global, multi‐annual (2000–2007) burnt area product at 1 km resolution

Abstract

This paper reports on the development and validation of a new, global, burnt area product. Burnt areas are reported at a resolution of 1 km for seven fire years (2000 to 2007). A modified version of a Global Burnt Area (GBA) 2000 algorithm is used to compute global burnt area. The total area burnt each year (2000–2007) is estimated to be between 3.5 million km2 and 4.5 million km2. The total amount of vegetation burnt by cover type according to the Global Land Cover (GLC) 2000 product is reported. Validation was undertaken using 72 Landsat TM scenes was undertaken. Correlation statistics between estimated burnt areas are reported for major vegetation types. The accuracy of this new global data set depends on vegetation type.

Burned Area Mapping in the North American Boreal Forest Using Terra-MODIS LTDR (2001–2011): A Comparison with the MCD45A1, MCD64A1 and BA GEOLAND-2 Products

“…Masks are combined to create a masked pixel product that is computed on a daily basis. The primary processing algorithm makes use of a temporal index, I, that allows for the classification of burned and unburned surfaces [18]. A pixel is classified as -burned‖ if the pixel value in the 112 × 112 pixel array window, I, is lower than three mean values minus two standard deviations.…”

“…The first version, -V0‖, is an implementation of the L3JRC BA algorithm [18] for the region of continental Africa and was developed under the Global Burned Area (GBA) 2000 project [47].…”

“…However, recent published studies on BA products derived from the daily coarse spatial resolution imagery [18][19][20][21][22][23] on a continental/global scale do not provide a quantitative comparison that spans the 2001-2011 decade at the final product level. Besides, as far as we know, there has not been any burned area products developed using the LTDR dataset generated from MODIS imagery.…”

“…(MCD45A1) product [24][25][26], MODIS Collection 5.1 Direct Broadcast Monthly Burned Area Product (MCD64A1) [27] and the Burned Area GEOLAND-2 (BA GEOLAND-2) product derived from VEGETATION, which was an improvement of the Global Burned Area (GBA2000) product and the burned area product developed by the consortium of three academies under the supervision of the Joint Research Centre of the European Commission (L3JRC) [18].…”

On the extent of fire-induced forest degradation in Mato Grosso, Brazilian Amazon, in 2000, 2005 and 2010

“…Fire detection and burned area mapping are most typically performed with coarse spatial resolution (.250 m) satellite data which offer high temporal frequency enabling near real time monitoring of the development of the burning season (Setzer and Pereira 1991;Tansey et al 2008;Giglio et al 2009;Morton et al 2011). However, burned area monitoring limited to coarse spatial resolution data may distort both the overall burned area estimate and the spatial distribution of burned area (Laris 2005;Miettinen and Liew 2009).…”
