Please review the Data Quality Information Summary before using the SORCE data.
The raw telemetry (level 0) data are nominally downlinked twice a day from the spacecraft to ground stations at NASA's Wallops Flight Facility and a second in Santiago, Chile. The daily volume of data is roughly 120 Megabytes. SORCE data processing takes place at the LASP Science Operations Center where the higher level products are generated, usually within 24 hours of receiving the raw data.
Level 1A (time referenced instrument counts), level 1B (counts including calibration paramters and ephemeris data) and level 2 (irradiances at instrument resolution) data products are intended as internal products for use by the SORCE science team.
The standard data products which are available from the GES DISC include seven level 3 products, five contain solar spectral irradiance (SSI) data and the other two contain total solar irradiance (TSI) data. All SORCE data products are written in an ASCII table format. How to obtain the SORCE standard products is described in the data access section. The tables below summarize the SORCE standard data products:
| Name | Description | File Sizes |
|---|---|---|
| SOR3SIMD SORCE Level 3 Solar Spectral Irradiance Daily Average | Contains the irradiance data from the SIM (300-2000 nm range at 1-27 nm intervals) instrument. These are averaged to provide daily values of the solar irradiance on a fixed wavelength scale, and normalized to one astronomical unit. | ASCII Format ~125 MB |
| SOR3SOLFUVD SORCE SOLSTICE FUV Level 3 Solar Spectral Irradiance Daily Means | Contains the irradiance data from the SOLSTICE Far UV (115-180 nm range at 1 nm intervals) instrument. These are averaged to provide daily values of the solar irradiance on a fixed wavelength scale, and normalized to one astronomical unit. | ASCII Format ~14 MB |
| SOR3SOLMUVD SORCE SOLSTICE FUV Level 3 Solar Spectral Irradiance Daily Means | Contains the irradiance data from the SOLSTICE Mid UV (180-310 nm range at 1 nm intervals) instrument. These are averaged to provide daily values of the solar irradiance on a fixed wavelength scale, and normalized to one astronomical unit. | ASCII Format ~27 MB |
| SOR3XPS6 SORCE XPS Level 3 Solar Spectral Irradiance 6-Hour Means | Contains the irradiance data from the XPS (0.1-27nm, as well as Lyman-alpha 121 nm) instrument. These are averaged to provide 6-hourly values of the solar irradiance on a fixed wavelength scale, and normalized to one astronomical unit. | ASCII Format ~4.7 MB |
| SOR3XPSD SORCE XPS Level 3 Solar Spectral Irradiance Daily Means | Contains the irradiance data from the XPS (0.1-27nm, as well as Lyman-alpha 121 nm) instrument. These are averaged to provide daily values of the solar irradiance on a fixed wavelength scale, and normalized to one astronomical unit. | ASCII Format ~1.3 MB |
| Name | Description | File Sizes |
|---|---|---|
| SOR3TSI6 SORCE Level 3 Total Solar Irradiance 6-Hour Average | Contains the total solar irradiance (a.k.a solar constant) data collected by the TIM instrument covering the full wavelength spectrum averaged at 6-hourly intervals. The data are normalized to one astronomical unit. | ASCII Format 0.2 - 1.0 MB (cummulative file, delivered once a month) |
| SOR3TSID SORCE Level 3 Total Solar Irradiance Daily Average | Contains the total solar irradiance (a.k.a solar constant) data collected by the TIM instrument covering the full wavelength spectrum averaged at daily intervals. The data are normalized to one astronomical unit. | ASCII Format 0.1 - 0.3 MB (cummulative file, delivered once a month) |
