GOES overview plot, March 17, 2013

SPEDAS provides command-line and GUI access for loading, processing and analyzing GOES space physics data. The GOES data is made available by the NOAA National Geophysical Data Center (NGDC).

To check the data availability for a specific GOES spacecraft/instrument on a certain day, use the data availability tool: GOES Data Availability

GOES 8-12 SEM Data

For a full description of the GOES 8-12 instruments and their data products, see the GOES 8-12 databook

Examples

Fluxgate Magnetometer (FGM)

To load and plot the magnetic field measured by the FGM instrument onboard GOES-12 on 3/22/2008:

SPEDAS> goes_load_data, trange=['2008-03-22', '2008-03-23'], datatype='fgm', probes='12', /avg_1m

SPEDAS> tplot, 'g12_H_enp'

Energetic Particle Sensor (EPS)

Load and plot the 1-min averaged 2.4MeV proton flux as measured by the EPS instrument onboard GOES-12 on March 22, 2008:

SPEDAS> goes_load_data, trange=['2008-03-22', '2008-03-23'], datatype='eps', probes='12', /avg_1m

SPEDAS> tplot, 'g12_prot_2.4MeV_flux'

We can also plot the integral flux of electrons at 0.6 MeV:

SPEDAS> tplot, 'g12_elec_0.6MeV_iflux'

X-ray Sensor (XRS)

To load and plot the 1-min averaged X-ray flux as measured by the XRS instrument onboard GOES-10 on March, 22, 2008:

SPEDAS> goes_load_data, trange=['2008-03-22', '2008-03-23'], datatype='xrs', probes='10', /avg_1m

SPEDAS> tplot, 'g10_xrs_avg'

GOES 13-15 SEM Data

To check the current status of the GOES 13-15 data, see GOES 13-15 status

For a full description of the GOES 13-15 instruments and their data products, see the GOES 13-15 databook

Examples

Fluxgate Magnetometer (FGM)

Load and plot 1-min averaged data for both FGM sensors on GOES-15 for the day of March 17, 2013:

SPEDAS> goes_load_data, trange=['2013-03-17', '2013-03-18'], datatype='fgm', probes='15', /avg_1m

SPEDAS> tplot, 'g15_H_enp_*'

Magnetospheric Electron Detector (MAGED)

Load and plot 1-min averaged, corrected (for deadtimes) flux of 40keV, 75keV electrons measured by the MAGED instrument on GOES-15 for the day of March 17, 2013:

SPEDAS> goes_load_data, trange=['2013-03-17', '2013-03-18'], datatype='maged', probes='15', /avg_1m

SPEDAS> tplot, ['g15_maged_40keV_dtc_cor_flux', 'g15_maged_75keV_dtc_cor_flux']

To calculate the pitch angles corresponding to each MAGED telescope head (FGM data must be loaded):

SPEDAS> goes_lib ; compile the GOES library routines

SPEDAS> goes_pitch_angles, 'g15_H_enp_1', 'g15_HT_1', prefix = 'g15'

SPEDAS> tplot, 'g15_pitch_angles'

Magnetospheric Proton Detector (MAGPD)

Load and plot the 95 keV proton flux from the MAGPD instrument onboard GOES-15 for the day of March 17, 2013:

SPEDAS> goes_load_data, trange=['2013-03-17', '2013-03-18'], datatype='magpd', probes='15', /avg_1m

SPEDAS> tplot, 'g15_magpd_95keV_dtc_cor_flux'

Electron, Proton, Alpha Detector (EPEAD)

Load and plot the 2.5MeV, uncorrected proton flux as observed by the GOES-15 EPEAD instrument for the day of March 17, 2013:

SPEDAS> goes_load_data, trange=['2013-03-17', '2013-03-18'], datatype='epead', probes='15', /avg_1m

SPEDAS> tplot, 'g15_prot_2.5MeV_uncor_flux'

To calculate and plot the center pitch angles for the east and west heads of the EPEAD instrument, first load the FGM data:

SPEDAS> goes_load_data, trange=['2013-03-17', '2013-03-18'], datatype='fgm', probes='15', /avg_1m

then compile the GOES library file, goes_lib:

SPEDAS> goes_lib ; compile GOES support routines

and finally use goes_epead_center_pitch_angles to calculate the pitch angles from the magnetic field in spacecraft coordinates:

SPEDAS> goes_epead_center_pitch_angles, 'g15_Bsc_1', 'g15_BTSC_1'

SPEDAS> tplot, 'goes_epead_center_pitch_angles'

High Energy Proton and Alpha Detector (HEPAD)

Load and plot the 375MeV proton flux as observed by the GOES-15 HEPAD instrument for the day of March 17, 2013:

SPEDAS> goes_load_data, trange=['2013-03-17', '2013-03-18'], datatype='hepad', probes='15', /avg_1m

SPEDAS> tplot, 'g15_hepadp_375MeV_flux'

X-ray Sensor (XRS)

Load and plot the X-rays measured by the GOES-15 XRS instrument for the day of March 17, 2013:

SPEDAS> tplot, 'g15_xrs_avg'
