;NAME:
;iug_load_meteor_srp_txt
;
;PURPOSE:
; Queries the RISH servers for the meteor data (text format) taken by
; the meteor wind radar (MWR) at Serpong and loads data into tplot format.
;
;SYNTAX:
; iug_load_meteor_srp_txt, parameter = parameter, length=length, downloadonly = downloadonly, $
; trange = trange, verbose=verbose
;
;KEYWOARDS:
; LENGTH = Data length '1-day' or '1-month'. For example, iug_load_meteor_srp_txt, length = '1_day'.
; A kind of parameters is 2 types of '1_day', and '1_month'.
; PARAMETER = Data parameter. For example, iug_load_meteor_srp_txt, parameter = 'h2t60min00'.
; A kind of parameters is 4 types of 'h2t60min00', 'h2t60min00', 'h4t60min00', 'h4t60min00'.
; The default is 'all'.
; 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.
; VERBOSE: [1,...,5], Get more detailed (higher number) command line output.
