;+ ; ;NAME: ;iug_load_mu_iono_drift_nc ; ;PURPOSE: ; Queries the Kyoto_RISH servers for ionospheric plasma drift velocity in netCDF format ; estimated from the incoherent scatter observation of the MU radar at Shigaraki ; and loads data into tplot format. ; ;SYNTAX: ; iug_load_mu_iono_drift_nc, downloadonly = downloadonly, $ ; trange = trange, verbose=verbose ; ;KEYWOARDS: ; trange = (Optional) Time range of interest (2 element array), if ; this is not set, the default is to prompt the user. Note ; that if the input time range is not a full day, a full ; day's data is loaded. ; /downloadonly, if set, then only download the data, do not load it ; into variables. ; ;CODE: ; A.
