Correction of Effect of Plant Chlorophyll Fluorescence Based on Optical Path Distribution Method
摘要
基于全球植被的荧光分布,利用GOSAT数据,同步反演了光子光程概率分布密度函数因子和755 nm处的荧光强度,将反演结果与TCCON站点的结果进行了对比。结果表明:对于受植物叶绿素荧光影响较大的Park Falls(45.9°N,90.3°W)站点附近的GOSAT数据,考虑荧光影响前后的二氧化碳(CO2)反演结果的最大偏差为1.6×10
-6;对于受荧光影响稍小的Sodankyla(67.4°N,26.6°E)站点附近的GOSAT数据,最大偏差为0.8×10
-6,散射校正荧光影响可以使平均误差缩小到0.1×10
-6左右。
Abstract
Based on global vegetation fluorescence distribution, photon path probability distribution density function factor and the fluorescence intensity at 755 nm are synchronously inverted with GOSAT data. The inversion results are compared with the results of TCCON site. The results show that for the GOSAT data near the Park Falls (45.9°N, 90.3°W) site, which is greatly affected by plant chlorophyll fluorescence, the maximum deviation between CO2 inversion results before and after considering the effect of fluorescence is 1.6×10
-6. While for the GOSAT data of near Sodankyla site which is slightly affected by fluorescence, the maximum deviation is 0.8×10
-6. The scattering correction of the fluorescence effect can reduce the average error to about 0.1×10
-6.
