ESA Fire Climate Change Initiative (Fire_cci): AVHRR-LTDR Burned Area Grid product, version 1.1

The ESA Fire Disturbance Climate Change Initiative (CCI) project has produced maps of global burned area derived from satellite observations. The AVHRR - LTDR Grid v1.1 product described here contains gridded data of global burned area derived from spectral information from the AVHRR (Advanced Very High Resolution Radiometer) Land Long Term Data Record (LTDR) v5 dataset produced by NASA. The dataset provides monthly information on global burned area on a 0.25 x 0.25 degree resolution grid from 1982 to 2018. The year 1994 is omitted as there was not enough input data for this year. The dataset is distributed in NetCDF files, and it includes 4 layers: sum of burned area, standard error, fraction of burnable area and fraction of observed area. For further information on the product and its format see the Product User Guide.

欧洲空间局（ESA）火灾扰动气候变化倡议（CCI）项目已基于卫星观测数据生成全球过火面积制图成果。本文所述的AVHRR-LTDR Grid v1.1产品，包含基于美国国家航空航天局（NASA）生成的AVHRR（先进甚高分辨率辐射计，Advanced Very High Resolution Radiometer）陆地长期数据记录（Land Long Term Data Record, LTDR）v5数据集的光谱信息所提取的全球过火面积格点数据。该数据集提供了1982年至2018年间分辨率为0.25°×0.25°的全球月度过火面积信息。因1994年输入数据不足，该年份数据予以剔除。该数据集以NetCDF文件格式分发，包含4个数据层：过火面积总和、标准误差、可燃面积占比及观测面积占比。如需了解该产品及其格式的更多详情，请参阅《产品用户指南》。
