Detection of Spatiotemporal Extreme Changes in Atmospheric CO2 Concentration Based on Satellite Observations
TL;DR: A spatiotemporal extreme change detection method for atmospheric CO2 concentrations using column-averaged CO2 dry air mole fraction retrieved from the Greenhouse gases Observing SATellite (GOSAT) from 1 June 2009 to 31 May 2016 is developed.
Improving Chlorophyll Fluorescence Retrieval Using Reflectance Reconstruction Based on Principal Components Analysis
Xinjie Liu,Liangyun Liu +1 more
TL;DR: The pFLD method, based on principal components analysis to reconstruct the reflectance spectra, showed better performance at the O2-B band, particularly when the spectral resolution (SR) or the signal-to-noise ratio was relatively low.

Lu Yao,Dongxu Yang,Yi Liu,Jing Wang,Liangyun Liu,Shanshan Du,Zhaonan Cai,Naimeng Lu,Daren Lyu,Maohua Wang,Zengshan Yin,Yuquan Zheng +11 more
TL;DR: Based on the Institute of Atmospheric Physics Carbon Dioxide Retrieval Algorithm for Satellite Remote Sensing (IAPCAS) platform, the authors successfully retrieved the TanSat global SIF product spanning the period of March 2017 to February 2018 with a physically based algorithm.
Assessment of spatio-temporal variations in vegetation recovery after the Wenchuan earthquake using Landsat data
TL;DR: Wang et al. as discussed by the authors assessed ecological changes within a few years of the Wenchuan earthquake through satellite observations of vegetation dynamics in the earthquake area, and found that the entire mountainous disaster area had recovered by 68.45% 3 years after the 2008 earthquake.
