Abstract:

Sun-Induced Chlorophyll Fluorescence 锛圫IF锛� is an effective probe characterizing vegetation photosynthesis. Various global SIF satellite remote sensing products have been derived and widely used. However锛� the performance and consistency of different products in China are still unclear. CSIF锛� GOSIF锛� SIFoco2-005锛� SIFLUE 锛圫IFLUE_JJ/SIFLUE_PK锛夛紝 and SIF005 were validated using the ground observations of four farmland sites from ChinaSpec锛� and their consistency was analyzed. Results showed that锛� 锛�1锛� The performance of different products is different in different places and overestimation occurred in three farm stations. SIFLUE performs well as a whole锛� followed by GOSIF锛� SIF005 and SIFoco2_005. 锛�2锛� The spatial pattern of the annual mean SIF and annual maximum SIF in 2016 based on different products is highly consistent锛� but with different magnitude. The national averaged value of annual mean SIF for SIFLUE_PK锛� SIF005锛� SIFoco2_005锛� SIFLUE_JJ锛� GOSIF andCSIF is 0.21锛� 0.17锛� 0.15锛� 0.13锛� 0.11 and 0.08 W m-2 渭m-1 sr-1锛� respectively. The national averaged value of annual maximum SIF for SIFLUE_PK锛� SIF005锛� SIFoco2_005锛� GOSIF锛� CSIF and SIFLUE_JJ is 0.48锛� 0.44锛� 0.36锛� 0.33锛� 0.31锛� and 0.30 W m-2 渭m-1 sr-1锛� respectively. 锛�3锛� The annual mean value of GOSIF/CSIF and SIFLUE_PK/SIF005 significantly increased and decreased in 23.6%/18.6% and 16.3%/14.7% areas respectively from 2008 to 2016. The national averaged trends of GOSIF锛� CSIF锛� SIFLUE_PK锛� and SIF005 is 0.001 6锛� 0.001 2锛� -0.003 6锛� and -0.001 4 W m-2 渭m-1 sr-1 a-1锛� respectively. SIFLUE_JJ showed no significant change. 锛�4锛� The annual maximum value of CSIF/GOSIF and SIFLUE_PK/SIF005 significantly increased and decreased in 10.1%/9.9% and 16.9%/22.3% areas respectively during the period of 2008 to 2016. The national averaged trends of GOSIF锛� CSIF锛� SIFLUE_PK锛� and SIF005 is 0.002 9锛� 0.002 2锛� -0.008 0锛� and -0.008 1 W m-2 渭m-1 sr-1 a-1锛� respectively. SIFLUE_JJ showed no significant change.
