Descripción
| In support of the IPCC, the ESA Climate Change Initiative (CCI) programme comprises the participation of different projects, each focusing on the production of global coverage of an Essential Climate Variable (ECV). The ECV Fire Disturbance (Fire_cci) provides validated, error-characterised, global and regional data sets of burned areas (BA) derived from existing satellite observations. The Fire_cci BA products consist of a Pixel and Grid product addressing the needs and requirements of climate, atmospheric and ecosystem scientists and researchers supporting their modelling efforts. Further information on the ESA CCI Programme and a comprehensive documentation on the underlying algorithms, work flow, production system and product validation is publicly accessible on https://www.esa-fire-cci.org/. FireCCIS1SA10 provides burned area (BA) information over a large demonstrator area (LDA) located in tropical South America for the year 2017. It is based on an algorithm that uses Sentinel-1 SAR information, with MODIS hotspots and land cover as auxiliary information, to detect areas that have burned due to wildfires. The product is provided in monthly tiles in geographical coordinates with a spatial resolution of 0.00035932447 degrees (approx. 40 m). |

Tipo de datos
| The dataset is provided in monthly 5x5-degree tiles, with 3 layers accompanied by an XML metadata file, and all packed in a tar.gz file. The complete dataset is comprised of 408 tar.gz files. The product is a set of single-layer GeoTIFF files with the following naming convention: ${Indicative Date}-ESACCI-L3S_FIRE-BA-${Indicative sensor}[-${Additional Segregator}]-${xx.x}[-${layer}].tif. ${Indicative Date} is the identifying date for this data set. Format is YYYYMMDD, where YYYY is the four digit year, MM is the two digit month from 01 to 12 and DD is the two digit day of the month from 01 to 31. For monthly products the date is set to 01. ${Indicative sensor} is SAR. ${Additional Segregator} is the AREA_${TILE_CODE} being the tile code described in the Product User Guide. ${File Version} is the File version number in the form n{1,}[.n{1,}] (That is 1 or more digits followed by optional . and another 1 or more digits.). ${layer} is the code for the layer represented in each file, being: JD: layer 1, CL: layer 2, and LC: layer 3. An example is: 20170301-ESACCI-L3S_FIRE-BA-SAR-AREA_h22v18-fv1.0-JD.tif. Layer 1: Date of the first detection; Pixel Spacing = 0.00035932447 deg (approx. 40m); Pixel value = Day of the year, from 1 to 365 (or 366). A value of 0 is included when the pixel is not burned in the month; a value of -1 is allocated to pixels that are not observed in the month; a value of -2 is allocated to pixels that are not burnable (build up areas, bare areas, , snow and/or ice, open water). Data type = Integer; Number of layers = 1; Data depth = 16. Layer 2: Confidence Level; Pixel Spacing = 0.00035932447 deg (approx. 40m); Pixel value = 0 to 100, where the value is the probability in percentage that the pixel is actually burned, as a result of the different steps of the burned area classification. The higher the value, the higher the confidence that the pixel is actually burned. A value of 0 is allocated to pixels that are not observed in the month, or not taken into account in the burned area processing (non burnable). Data type = Byte; Number of layers = 1; Data depth = 8. Layer 3: Land cover of that pixel, extracted from the Land Cover CCI v2.0.7 product corresponding to 2015. N is the number of the land cover categories in the reference map. It is only valid when layer 1 > 0. Pixel value is 0 to N under the following codes: 10 = Cropland, rainfed; 20 = Cropland, irrigated or post-flooding; 30 = Mosaic cropland (>50%) / natural vegetation (tree, shrub, herbaceous cover) (<50%); 40 = Mosaic natural vegetation (tree, shrub, herbaceous cover) (>50%) / cropland (<50%); 50 = Tree cover, broadleaved, evergreen, closed to open (>15%); 60 = Tree cover, broadleaved, deciduous, closed to open (>15%); 70 = Tree cover, needleleaved, evergreen, closed to open (>15%); 80 = Tree cover, needleleaved, deciduous, closed to open (>15%); 90 = Tree cover, mixed leaf type (broadleaved and needleleaved); 100 = Mosaic tree and shrub (>50%) / herbaceous cover (<50%); 110 = Mosaic herbaceous cover (>50%) / tree and shrub (<50%); 120 = Shrubland; 130 = Grassland; 140 = Lichens and mosses; 150 = Sparse vegetation (tree, shrub, herbaceous cover) (>15%); 160 = Tree cover, flooded, fresh or brackish water; 170 = Tree cover, flooded, saline water; 180 = Shrub or herbaceous cover, flooded, fresh/saline/brackish water; Pixel Spacing = 0.00035932447 deg (approx. 40m); Data type = Byte; Number of layers = 1; Data depth = 8 |
