Fire radiative power and active fire pixels from 2020 to present derived from satellite observations

This dataset provides active fire (AF) and fire radiative power (FRP) products derived from observations made by the Sea and Land Surface Temperature Radiometer (SLSTR) operating concurrently onboard the European Sentinel-3A and -3B satellites. These products are generated from the non-time critical (NTC) Level 2 AF detection and FRP product from European Space Agency (ESA). The AF, FRP and the Burnt Areas are Essential Climate Variables (ECV) from the Global Observing System for Climate (GCOS). Burnt Area is provided through a different catalogue entry.
The AF & FRP products encompass a Level 2 summary product which provides a text-based summary of the Level 2 AF detection and FRP data collected over the period of one month across the globe but separated for the different sentinel satellites Sentinel-3A and 3B and the observing time – nighttime or daytime in v1.2. In addition, three Level 3 ‘synthesis products’ are also provided, each one grids the Level 2 AF and the FRP data at various spatial and temporal resolutions along with some adjustments for cloud cover that blocks the fires from the satellite sensors view. Following Level 3 ‘synthesis products’ are available:

V1.0 (February 2020 to February 2021):

daily global Level 3 FRP product generated on a global 0.1 degree resolution grid. AF data coming from observations made by both Sentinel-3A (S3A) and -3B (S3B) have separate layers in this product. Only night-time land observations are included at this moment, the full daytime will be provided in the future once the corresponding NTC Level 2 FRP data are available.
27 day global Level 3 FRP product also derived at 0.1 degree grid cell resolution but summarising the FRP data from both Sentinel-3A and -3B. This time period matches the Sentinel-3 satellites standard orbital repeat cycle.
monthly global Level 3 FRP product which provides global AF detection and FRP data at a grid cell size of 0.25 degrees. This resolution matches the MODIS Climate Model-ling Grid (CMG) active fire product.

V1.2 (January 2021 – to present)

the daily global Level 3 AF & FRP products are generated on a global 0.1-degree reso-lution grid. Based on the Level 2 AF & FRP data, the daily global Level 3 AF & FRP products are separated by the observations made by Sentinel-3A or -3B and the night-time and daytime land observations.
the 27day global Level 3 AF & FRP products are also derived at 0.1-degree grid cell resolution but summarise the AF & FRP data over 27 days but also separated by the observations made by Sentinel-3A or -3B and the night-time and daytime land obser-vations. This time period matches the Sentinel-3 satellites standard orbital repeat cy-cle.
the monthly global Level 3 AF & FRP product provides global AF detection and FRP data at a grid cell size of 0.25 degrees but also separated by the observations made by Sentinel-3A or -3B and the night-time and daytime land observations. This resolu-tion matches the MODIS Climate Modelling Grid active fire product.

The purpose of these AF and FRP products is to provide a summarised and 'easy to use' version of the Level 2 AF and FRP products, as well as providing the AF and FRP information in a consistently gridded format. The latter in particular is designed to be suitable for use in global modelling, trend analysis and model evaluation.
The AF and FRP were produced on behalf of the Copernicus Climate Change Service and have been designed to be broadly comparable with the equivalent Fire Burnt Area product, since they are likely to be used in combination with them to provide a long-term FRP time-series.

本数据集提供由欧洲哨兵-3A和-3B卫星上同时运行的海洋和陆地表面温度辐射计（SLSTR）所观测到的活跃火灾（AF）和火灾辐射功率（FRP）产品。这些产品源自欧洲航天局（ESA）的非时间敏感级（NTC）2级AF检测和FRP产品。AF、FRP及焚烧区域均为全球气候观测系统（GCOS）的关键气候变量（ECV）。焚烧区域通过不同的目录条目提供。AF与FRP产品包括2级汇总产品，该产品以文本形式概述了在全球范围内收集的一个月内的2级AF检测和FRP数据，但根据不同的哨兵卫星（Sentinel-3A和3B）和观测时间（v1.2中的夜间或白天）进行区分。此外，还提供了三个3级‘综合产品’，每个产品以不同的空间和时间分辨率将2级AF和FRP数据进行网格化，并对遮挡卫星传感器的火灾的云层覆盖进行了调整。以下为后续的3级‘综合产品’：

V1.0（2020年2月至2021年2月）：
每日全球3级FRP产品，在全球0.1度分辨率网格上生成。此产品中，来自哨兵-3A（S3A）和-3B（S3B）的AF数据有独立的层。目前仅包含夜间陆地观测，未来一旦可获得相应的NTC 2级FRP数据，将提供全天候观测。
27天全球3级FRP产品，同样在0.1度网格单元分辨率下生成，但汇总了来自哨兵-3A和-3B的FRP数据。此时间段与哨兵-3卫星的标准轨道重复周期相匹配。
每月全球3级FRP产品，以0.25度网格单元大小提供全球AF检测和FRP数据，其分辨率与MODIS气候模型网格（CMG）的活跃火灾产品相匹配。

V1.2（2021年1月至今）：
每日全球3级AF与FRP产品在全球0.1度分辨率网格上生成。基于2级AF与FRP数据，每日全球3级AF与FRP产品根据哨兵-3A或-3B的观测以及夜间和白天陆地观测进行区分。
27天全球3级AF与FRP产品也在0.1度网格单元分辨率下生成，但汇总了27天内的AF与FRP数据，并按哨兵-3A或-3B的观测以及夜间和白天陆地观测进行区分。此时间段与哨兵-3卫星的标准轨道重复周期相匹配。
每月全球3级AF与FRP产品以0.25度网格单元大小提供全球AF检测和FRP数据，并按哨兵-3A或-3B的观测以及夜间和白天陆地观测进行区分。此分辨率与MODIS气候模型网格（CMG）的活跃火灾产品相匹配。

这些AF和FRP产品的目的是提供一个简化的、易于使用的2级AF和FRP产品的版本，并提供以一致网格格式呈现的AF和FRP信息。特别是后者旨在适用于全球建模、趋势分析和模型评估。
AF和FRP由哥白尼气候变迁服务生产，并被设计为与等效的火灾焚烧面积产品广泛可比，因为它们很可能会与这些产品结合使用，以提供长期FRP时间序列。
