Data Availability Chart

Reading Data Files

The following readers are available for the data files in the table above:

Quick Overview

The SORCE instrument suite produces two primary data products: Total Solar Irradiance (TSI) and Solar Spectral Irradiance (SSI) from 0.1 nm to 40 nm and from 115 nm to 2416 nm, with other secondary data products produced and disseminated as a means to more directly serve other scientific communities. TSI data products are formulated using measurements made by the SORCE TIM instrument, and are available in both daily average or 6-hourly average formats. The SSI data product is comprised of measurements made by the four SORCE spectral instruments, with XPS making measurements from 0.1 – 40 nm, SOLSTICE-A from 115-180 nm, SOLSTICE-B from 180-310 nm, and SIM from 310-2416 nm. The spectral interval from 40-115 nm is not covered by the SORCE mission

SORCE data products are available for public access. SORCE data may be accessed from three different locations:

Refinement of data processing algorithms and some on-orbit characterization of the SORCE instruments continue. Please read the release notes on the TSI and the SSI web pages for detailed quality information about the products you may be interested in.

Science Data Processing

The SORCE Science Data System (SDS) performs all science data production activities. It consists of the hardware and software components necessary to generate, manage, and distribute all SORCE standard science data products. The SORCE SDS routinely produces total solar irradiance and solar spectral irradiance data products on a daily basis, which are formulated using measurements from the four primary instruments onboard the SORCE spacecraft. The Science Data System utilizes raw spacecraft and instrument telemetry, routinely-maintained calibration data, and other ancillary information to produce and distribute a variety of data products that have been corrected for all known instrumental and operational effects.

The table at the top of this page summarizes the core SORCE data products. SORCE provides routine daily measurements of TSI, SSI from 0.1 nm to 40 nm and 115 nm to 2416 nm, and other solar-irradiance derived products that support the atmospheric, climate, and space weather communities. TSI data products are formulated using measurements made by the SORCE TIM instrument, and are available in both daily average or 6-hourly average formats. The SSI data products, including the Mg index, are comprised of measurements made by the SORCE spectral instruments. Routine calibration and validation is a significant effort to maintain the high quality of the solar irradiance data products.

Data processing is performed automatically with the production of data through Level 3 two to five days after the data has been downlinked from the spacecraft, allowing for telemetry retransmissions and receipt of definitive spacecraft orbital ephemerides from NORAD. TSI and SSI data products are made available to the public immediately after they are produced by the data processing system, following automated quality checks.

The data products are available by direct download or interactive access on the LASP Interactive Solar Irradiance Datacenter (LISIRD), and are formally delivered to the GES DISC on a daily basis for long-term archival. Dissemination of SORCE data products via the SORCE website at LASP enhances convenience for users as data access methods are tailored to those most functional for retrieving SORCE solar irradiance data. The SORCE project at LASP indexes and maintains a full archive of data products, making possible various and flexible data access interfaces that are intended to provide added convenience to end-users. Configuration management of data is built into the SORCE data system, owing to integration of the SORCE data processing and dissemination components.
