SOSMAG_CSV_TO_TPLOT

[Previous Routine] [Next Routine] [List of Routines]

 Procedure:
         sosmag_csv_to_tplot

 Purpose:
         Load SOSMAG data from a structure s into tplot variables

 Keywords:
         s : a structure with sosmag data, usually the result of read_csv()
         tformat (optional): string, time format, for example 'DD.MM.YYYY hh:mm:ss'
                             default time format is 'YYYY-MM-DDThh:mm:ss.fffZ'
                             for more details, see time_struct.pro
         desc (optional): string, description of the data
         prefix (optional): string, prefix for tplot variables
         suffix (optional): string, suffix for tplot variables

 Notes:

SOSMAG_LOAD_CSV

[Previous Routine] [List of Routines]

 Procedure:
         sosmag_load_csv

 Purpose:
         Load SOSMAG data from a local CSV file into tplot variables

 Keywords:
         filename : the csv filename, including the full path
         tformat (optional): string, time format, for example 'DD.MM.YYYY hh:mm:ss'
                             default time format is 'YYYY-MM-DDThh:mm:ss.fffZ'
         desc (optional): string, description of the data
         prefix (optional): string, prefix for tplot variables
         suffix (optional): string, suffix for tplot variables

 Notes:
   First, the user must register at the ESA web site, then download a csv file to his computer,
   and then he can load the csv file data into SPEDAS using "sosmag_load_csv, filename".

   To register, the user can go to the following web site and click on "capabilities".
     https://swe.ssa.esa.int/hapi/
   A new page will appear which includes links for registration.

   To download data as csv files, the user can use a web browser with the ESA HAPI web server.
   For example, the following URL downloads calibrated data (data product esa_gk2a_sosmag_recalib) for 2021/01/31 1am to 2am UTC:
   https://swe.ssa.esa.int/hapi/data?id=spase://SSA/NumericalData/GEO-KOMPSAT-2A/esa_gk2a_sosmag_recalib&time.min=2021-01-31T01:00:00.000Z&time.max=2021-01-31T02:00:00.000Z&format=csv

   And the following downloads real-time data (data product esa_gk2a_sosmag_1m):
   https://swe.ssa.esa.int/hapi/data?id=spase://SSA/NumericalData/GEO-KOMPSAT-2A/esa_gk2a_sosmag_1m&time.min=2021-01-31T01:00:00.000Z&time.max=2021-01-31T02:00:00.000Z&format=csv
