Solar-induced Chlorophyll Fluorescence from GOSAT's TANSO-FTS by the University of Leicester

Solar-induced Chlorophyll Fluorescence (SIF) data created from the Greenhouse Gas Observing Satellite (GOSAT) Level 1B data using an adapted version of the University of Leicester Full-Physics retrieval scheme (UoL-FP). These dataset contains both Level 2 and Level 3 S-polarised SIF. The Level 2 data are in daily files and are not averaged, whilst the Level 3 data are averaged spatially and temporally on both a monthly and weekly timescale. The SIF data was derived from L1B data from the TANSO-FTS ( Thermal and Near Infrared Sensor for carbon Observation - Fourier Transform Spectrometer) instrument on the GOSAT satellite. For each GOSAT sounding, the S-polarised spectra have been extracted from two narrow micro-windows outside the Oxygen A-band, at around 755 nm and 772 nm. For more information on the retrieval setup and bias correction, please see "Novel Methods for Atmospheric Carbon Dioxide Retrieval from the JAXA GOSAT and NASA OCO-2 Satellites - Part II: Remote Sensing of Chlorophyll Fluorescence" by Peter Somkuti.

本数据集基于温室气体观测卫星（Greenhouse Gas Observing Satellite, GOSAT）的1级B（Level 1B）数据，采用经适配改进的莱斯特大学全物理反演算法（University of Leicester Full-Physics retrieval scheme, UoL-FP）生成日光诱导叶绿素荧光（Solar-induced Chlorophyll Fluorescence, SIF）数据。数据集涵盖2级（Level 2）与3级（Level 3）两类S极化日光诱导叶绿素荧光数据。其中2级数据以单日文件形式存储，未经过平均处理；3级数据则分别在月、周两个时间尺度上完成空间与时间维度的平均。
本数据集的SIF数据源自GOSAT卫星搭载的热红外与近红外碳观测傅里叶变换光谱仪（Thermal and Near Infrared Sensor for carbon Observation - Fourier Transform Spectrometer, TANSO-FTS）获取的1级B数据。针对每一次GOSAT观测廓线，研究人员从氧A带外的两个窄微光谱窗口（分别位于约755 nm与772 nm波长处）提取了S极化光谱。
