L2 Daily Solar-Induced Fluorescence (SIF) from MetOp-B GOME-2, 2013-2021

This dataset provides Level 2 (L2) Solar-Induced Fluorescence (SIF) of chlorophyll estimates derived from the Global Ozone Monitoring Experiment 2 (GOME-2) instrument on the European Meteorological Satellite (EUMETSAT) MetOp-B with ~0.5 nm spectral resolution and wavelengths between 734 and 758 nm. GOME-2 covers global land (observations up to 75-degree solar zenith angle) at a resolution of approximately 40 km x 80. Data are provided for the period from 2013-04-01 to 2021-06-07. Each file contains daily raw and bias-adjusted solar-induced fluorescence along with quality control information and ancillary data. SIF measurements can provide information on the functional status of vegetation including light-use efficiency and global primary productivity that can be used for global carbon cycle modeling and agricultural applications. The GOME-2 SIF product is inherently noisy owing to low signal levels and has undergone only a limited amount of validation. The data are provided in netCDF (*.nc) format.

本数据集提供由欧洲气象卫星（EUMETSAT）MetOp-B上的全球臭氧监测实验2（GOME-2）仪器所获得的叶绿素水平2（L2）太阳诱导荧光（SIF）估计值，其光谱分辨率为约0.5纳米，波长范围在734至758纳米之间。GOME-2覆盖全球陆地（观测角度最高可达75度太阳天顶角），分辨率为约40公里×80公里。数据覆盖时间段为2013年4月1日至2021年6月7日。每个文件包含每日的原始和偏差校正太阳诱导荧光数据，以及质量控制信息和辅助数据。SIF测量可以提供有关植被功能状态的信息，包括光能利用效率和全球初级生产力，这些信息可用于全球碳循环模拟和农业应用。由于信号水平较低，GOME-2 SIF产品本身具有固有的噪声，并且仅经过有限程度的验证。数据以netCDF（*.nc）格式提供。
