The MCD45A1 product will not be generated beyond Collection 5.1. * The product is generated using Version 6 surface reflectance and active fire input data. * General improvement (reduced omission error) in burned area detection, including significantly better detection of small burns. * Modest reduction in burn-date temporal uncertainty Unlike MCD45A1, the MCD64A1 mapping algorithm is a hybrid one that supplements daily surface reflectance imagery with daily active fire data. The algorithm is a major extension to an earlier hybrid approach used by ( Roy et al., 1999 ) to map savanna burns in southern Africa with 1.1-km Advanced Very High Resolution Radiometer (AVHRR) imagery MCD45A1 detections showed similar precision over natural physiognomies. • MCD45A1 precision varied according to burning severity and time lag in satellite observation. • MCD45A omissions depended on land-cover and landscape patterns and conditions. • MCD45A1 detections were highly correlated to thermal anomaly data

Burned Area (MCD45A1, collection 5.1) The MODIS Burned Area product (short name: MCD45A1) identifies rapid changes in the daily surface reflectance, and uses that information to approximate the date of burning and map the spatial extent of recent fires (Giglio et al, 2015) Nevertheless, the MCD45A1 exhibited excellent performance in retrieving seasonal patterns of forest fire, with high fire occurrence in spring and autumn. On balance, more studies are required to assess and improve the MCD45A1 product and more precise data on forest burned areas in China are urgently needed

• Monthly Product (MCD45A1) - 500m approximate day of burning over month +/- 8 days - MODLAND 10x10 degree tiles - extensive QA & metadata -EOS-HDF • Annual Synthesis Product (forthcoming) - as monthly product but for calendar year • CMG 0.25 deg product (forthcoming) - aggregated information for climate modeling communit The Moderate Resolution Imaging Spectroradiometer (MODIS) is a payload imaging sensor built by Santa Barbara Remote Sensing that was launched into Earth orbit by NASA in 1999 on board the Terra (EOS AM) satellite, and in 2002 on board the Aqua (EOS PM) satellite. The instruments capture data in 36 spectral bands ranging in wavelength from 0.4 μm to 14.4 μm and at varying spatial resolutions. Comparisons of L3JRC and MCD45A1 burned areas using ground-based measurements and other satellite data were made in several major burning regions, and the results suggest that MCD45A1 generally performed better than L3JRC, although with a certain degree of underestimation in forest areas. The average annual L3JRC-based emissions were 123. Overall, September MCD45A1 polygons (2000-2012) compared well to the Landsat-based reference mapping (r 2 = 0.92) and were closely accompanied, on a monthly basis, by MOD14 and MYD14 hotspots (r 2 = 0.89), although large omissions errors, linked to landscape patterns, structures, and overall conditions depicted in each reference image, were. MCD45A1 C5) have also been included to analyze the impact of the changes made in the new versions. The Alaskan region was selected for two reasons. First, it is one of the few regions in the world that has an o cial database with detailed records of the area burned by all fires since 1940. These data wer

These results represent an improvement over the MCD45A1 product, which showed an agreement of R-2 = 0.67 and a slope = 0.42. The MCD64A1, BA-LTDR and MCD45A1 products underestimated the total burned area in the study region, whereas the BA GEOLAND-2 product overestimated it by approximately five-fold, with an agreement of R-2 = 0.05 The burned area is a critical parameter in estimating fire emissions. Recently, multiyear global burned area products with medium spatial resolution (1 km or 500 m) have been released, including the L3JRC product and the Collection 5 Moderate-Resolution Imaging Spectroradiometer (MCD45A1) product [6] The MCD45A1 product is produced from a change detection algorithm based on a bidirectional reflectance distribution function (BRDF) model [Roy et al., 2005]. MCD45A1 is a monthly product at 500 m resolution and is now available online from April 2000 to January 2009, reporting the approximate day of burning with 8-day precision Validation of the L3JRC and MCD45A1 burned areas was performed using data from ground-based measurements in Canada, the United States, Russia, and China. The results showed that MCD45A1 was more comparable to reference data, although it often underestimated in the boreal forests

The approach will be based on a merged form of the MODIS standard (MCD45A1) and direct broadcast (MCD64A1) burned area mapping algorithms used for Collection 6. We have found that the MCD45 product performes better in cropland burning areas, but the more noise tolerant direct broadcast product performs better under cloudy conditions, but not as. The product evaluated was the MCD45A1 of MODIS aboard Terra and Aqua platforms, which represent the burned areas, obtained daily, with spatial resolution of 500 meters, composed by a monthly mosaic, relative to 12 datasets for the 2010 and 2011 years. The evaluation of MCD45A1 product was performed by analysis an We also assessed the temporal reporting accuracy of the MODIS burned area products (MCD45A1 and MCD64A1). Averaged over the nine fires, the kriging method correctly mapped 73% of the pixels within the accuracy of a single day, compared to 33% for MCD45A1 and 53% for MCD64A1

The MODIS burned area product MCD45A1 (Roy et al. 2006) defined a fixed and wavelength-independent Z-score threshold to distinguish the difference of burned pixel reflectances between BRDF inversed and observed. However, it has been noted that fixed threshold methods performed poorly fo (MCD45A1) [1] as well as the Backup MODIS Burned Ar ea Product (hereafter BMBAP) [2]. Previous research on the validation of the MCD45A1 in South Africa was limited to only two Landsat 7 Enhanced Thematic Mapper plus (ETM+) scenes that covered the Lowveld sa vanna biome around the southern Kruger National Park [3] The MCD45A1 product is extracted from the atmospheric corrected Surface Reflectance Daily Data (MOD09GQK) acquired over 1 month. The method used is a change detection approach applied independently on each pixel over a defined period (Roy et al. 2005) The results for the two sample years (2006 and 2009) show that the older, non-hybrid products MCD45A1 and, MCD14ML were the best performers with Sørensen index (F1 score) reaching 0.42 and 0.26 in 2006, and 0.24 and 0.24 in 2009, respectively, while producer's accuracies (PA) were 30% and 43% in 2006, and 16% and 47% in 2009, respectively

Therefore, the objective of this work is to evaluate the MCD45A1 burned area product derived from MODIS sensor in Amazon tropical forest by comparing this dataset with the reference data derived from the mapping of burned areas in Acre State/Brazil acquired by TM sensor aboard of Landsat 5 and with a fieldwork that took place in November 2011 Four MODIS-derived products (MCD45A1 collection 5.1, MCD64A1 (collection 5.1 and 6), FireCCI51) were initially assessed to explore long-term fire frequency and land use/cover change relationships. The results indicated the product(s) could only detect half of the fires accurately. A further study was conducted using additional moderate spatial. A way of monitoring this is using remote sensing techniques. So the propose of the present article is to use the Modis product (MCD45A1) to identify and evaluated the burned areas in metropolitan region of Belo Horizonte, among the years of 2012 to 2016, which is validated with Landsat-8/OLI sensor data

MCD45A1 was particularly influenced by the temporal resolution used, as the two major peaks fell within the same month. At site level, the spatiotemporal depiction of central fires showed that GBA2000 presented the most clearly defined and consistent shapes. However, timing differences between close pixels were up to four months, an incoherence.

A new layer of data. Linkie found tapirs at 295 camera traps, which yielded a probability of occurrence of 0.43, meaning tapirs existed at 43 percent of the range-wide study area. He also discovered a relationship between occupancy and human impacts. Overall, tapirs were less likely to exist in areas with more human disturbance the MCD45A1 burned areas to independent reference data for several major burning regions (Canada, USA, Russia, and China), and found it to be reliable, especially for boreal forest regions.

Validation of the Two Standard MODIS Satellite Burned-Area Products and an Empirically-Derived Merged Product in South Afric The new algorithm is designed to be extremely tolerant of cloud and aerosol contamination, which affected the Collection 5.1 MCD45A1 product. As a consequence, the Collection 6 MCD64A1 product has significantly better detection of small burns, a modest reduction in burn-date temporal uncertainty, and a large reduction in the extent of unmapped. The MCD45A1 burned area product is at a medium resolution and has been validated to be reliable (Chang and Song 2009, Roy and Boschetti 2009). It is difficult to assess the uncertainty for the satellite-derived burned area (Hoelzemann et al 2004). In addition, the combustion factor was calculated from empirical formulae MCD45A1 is a monthly L3 500m product that approximates the date of burning, and maps the spatial extent of recent fires.
