LBA-ECO LC-39 Modeled Carbon Flux from Deforestation, Mato Grosso, Brazil: 2000-2006

This data set contains modeled estimates of carbon flux, biomass, and annual burning emissions across the Brazilian state of Mato Grosso from 2000-2006. The model, DEforestation CArbon Flux (DECAF), was used to provide annual carbon fluxes from large deforestation events (>25 ha) based on post-deforestation land use, and the frequency and duration of active fires during the deforestation process. Carbon fluxes associated with the conversion of Cerrado to mechanized crop production, fires in Cerrado, and managed pasture cover types were also estimated.

Model data outputs provided include:
* Estimated aboveground live biomass from DECAF in 2000 and 2004.
* Annual biomass burning emissions estimates for 2001-2005 from low, middle, and high emissions scenarios with DECAF. There are 15 GeoTIFF files for annual emissions which represent the carbon emissions per pixel in grams of carbon per m2 (g C m-2).

Model data inputs provided include:
* Annual burn trajectories for 2001 - 2005, including deforestation, Cerrado land cover conversion, and fires in pasture and Cerrado ecosystems unrelated to agricultural expansion. These data were assembled from three sources: MODIS 500-m burned area maps, annual deforestation based on data from the INPE PRODES program, and the conversion of Cerrado savannah/woodland to cropland estimated from land cover information from MODIS phenology metrics.
* Annual land cover data 2001-2004 for the portion of Mato Grosso covered by MODIS phenology metrics, tile h12v10, updated based on annual land cover changes in Amazon forest and Cerrado cover types.
* Monthly Normalized Difference Vegetation Index (NDVI) for MODIS tile h12v10 from 10/2000 - 09/2006, based on cloud and gap-filled 16-day NDVI data from MODIS Collection 4 16-day NDVI composites MOD13 product (Huete et al., 2002).

There are six compressed (*.gz) files with this data set.

本数据集包含了对巴西马托格罗索州2000-2006年间碳通量、生物量和年度燃烧排放的模拟估计。所采用的模型为森林砍伐碳通量模型（DEforestation CArbon Flux，简称DECAF），该模型基于砍伐后的土地利用情况以及砍伐过程中活跃火灾的频率和持续时间，对大于25公顷的大规模森林砍伐事件产生的年度碳通量进行估算。此外，还估计了将巴西高原（Cerrado）转化为机械化作物生产、Cerrado火灾以及管理型牧场覆盖类型相关的碳通量。模型提供的数据输出包括：
* 2000年和2004年DECAF估算的地上生物量。
* 2001-2005年不同排放情景（低、中、高）下的年度生物量燃烧排放估算。年度排放数据以15个GeoTIFF文件形式提供，代表每个像素的碳排放量，单位为每平方米克碳（g C m-2）。

模型提供的数据输入包括：
* 2001-2005年的年度燃烧轨迹，包括森林砍伐、巴西高原土地覆盖类型转换以及与农业扩张无关的牧场和巴西高原生态系统的火灾。这些数据来源于三个来源：MODIS 500米燃烧区域图、基于INPE PRODES项目数据的年度森林砍伐数据，以及根据MODIS物候学指标的土地覆盖信息估算的巴西高原草原/林地转化为农田。
* 2001-2004年马托格罗索州MODIS物候学指标覆盖区域的年度土地覆盖数据，基于亚马逊森林和巴西高原覆盖类型的年度土地覆盖变化更新。
* 2000年10月至2006年9月MODIS图块h12v10的月度归一化植被指数（NDVI），基于MODIS第4版16天NDVI复合产品（MOD13）的云和空隙填充16天NDVI数据（Huete等人，2002年）。

本数据集包含六个压缩文件（*.gz）。
