IVM data

The FORMOSAT-7/COSMIC-2 IVM data have been uploaded as two netCDF files, <i>ivm_rocket_20220115.nc</i> and <i>ivm_rocket_20230525.nc</i>. Each file contains the following variables: IVMut, IVMlon, IVMlat, IVMalt, IVMdensity, IVMtemperature, IVMzonal, IVMparallel, IVMperpendicular, and IVMlocaltime. Specifically, IVMut denotes Universal Time (UT) in hours; IVMlon, IVMlat, and IVMalt represent longitude, latitude, and altitude (km), respectively; IVMdensity and IVMtemperature represent ion density (cm⁻³) and ion temperature (K), respectively. IVMzonal, IVMparallel, and IVMperpendicular correspond to the three components of ion drift velocity relative to the magnetic field lines. IVMlocaltime represents the local time (hours).
