基于En-KF的内蒙古地区多源土壤水分数据融合

Multi-source Soil Moisture Data Fusion of Inner Mongolia Based on En-KF

综合利用内蒙古地区多源土壤水分数据,结合CLDAS土壤水分数据和地面站点实测数据,实现对研究区内的10 cm多源土壤水分融合。利用En-KF方法,使融合结果数据分辨率达0.01°,并对结果进行精度验证和误差分析。融合结果表明,基于CLDAS数据和地面实测土壤水分数据的融合提高了数据的精度。

Based on multi-source soil moisture data of Inner Mongolia,CLDAS soil moisture data and ground station measured data,10 cm multi-source soil moisture data fusion of Inner Mongolia was realized.The resolution of fusion result reached 0.01°by using En-KF method,and precision verification and error analysis of the result was carried out.Fusion result showed that the fusion based on CLDAS soil moisture data and ground station measured data could improve the precision of data.
