SORCE SOLSTICE: Solar Spectral Irradiance TSIS-Adjusted Values

SORCE SOLSTICE Level 3 High Resolution TSIS-Adjusted Values Solar Spectral Irradiance 24-Hour Means V002 is a dataset from NASA's GES DISC. It provides solar spectral irradiance measurements from 200 to 310 nm at a 0.025 nm grid resolution, calibrated using overlap between the SORCE and TSIS-1 SIM instruments. The data is stored in a single netCDF file containing variables for date, Julian day, wavelength, irradiance value, uncertainty, repeatability, original uncorrected value, and data quality.

Use Cases

• Modeling atmospheric photochemistry based on solar ultraviolet irradiance values.
• Studying long-term solar variability for climate research based on the TSIS-adjusted calibration.
• Validating and calibrating other solar observation instruments based on the high-resolution spectral grid.
• Analyzing solar irradiance uncertainty and repeatability for instrument performance assessment.

Strengths

• Provides solar spectral irradiance data at a high spectral resolution of 0.025 nm.
• Offers an alternate calibration using temporal overlap between SORCE and TSIS-1 SIM instruments.
• Data includes multiple variables such as irradiance uncertainty and repeatability for quality assessment.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 2020-02-25 23:59:59.999000; freshness should be verified.
• Row count is unknown, which may limit suitability assessment.
