Ionospheric Vertical Correlation Lengths Derived From IRI-2016 Model Errors
收藏资源简介：
Ionospheric vertical correlation lengths based on IRI-2016 model and Incoherent Scatter Radar (ISR) data. ISR used for this analysis: Jicamarca, Arecibo, Millstone Hill, Poker Flat ISR, and ResoluteBay North ISR. This metadata can be used for the construction of the covariance matrix for ionospheric data assimilation. Inside of the .nc file: lat=array of geomagnetic latitudes (degrees)<br> alt=arrays of altitudes (km)<br> vert_corr1=array of size (nalt, nlat), contains vertical correlation length above the reference point for different latitudes<br> vert_corr2=array of size (nalt, nlat), contains vertical correlation length below the reference point for different latitudes<br>
基于IRI-2016模型与非相干散射雷达（Incoherent Scatter Radar，ISR）观测数据构建的电离层垂直相关长度数据集。本次分析所采用的非相干散射雷达包括：吉卡马尔卡（Jicamarca）、阿雷西博（Arecibo）、米尔斯坦山（Millstone Hill）、波克弗拉特非相干散射雷达（Poker Flat ISR）以及ResoluteBay North ISR。该元数据可用于构建电离层数据同化的协方差矩阵。.nc格式文件内包含以下变量： lat：地磁纬度数组（单位：度） alt：海拔高度数组（单位：千米） vert_corr1：尺寸为(nalt, nlat)的数组，存储不同纬度下参考点上方的垂直相关长度 vert_corr2：尺寸为(nalt, nlat)的数组，存储不同纬度下参考点下方的垂直相关长度
