Short Name:

TSIS TIM Level 3 Total Solar Irradiance 6-Hour Means V03 (TSIS_TSI_L3_06HR) at GES DISC

Version 03 is the current release of this data product, and supercedes all previous versions. The TSIS TIM Level 3 Total Solar Irradiance (TSI) 6-Hour Means data product (TSIS_TSI_L3_06HR) uses measurements from the Total Irradiance Monitor (TIM) instrument over the entire spectrum, and averages them over a 6-hour period. TSIS-1 was launched on December 15, 2017 and mounted on the International Space Station (ISS) on December 30, 2017. TIM instrument has long-term repeatability with estimated uncertainties less than 0.014 W/m^2/yr (10 ppm/yr). Accuracy is currently reported as 0.48 W/m^2 (350 ppm), but expected to decrease as calibrations are refined and incorporated. Irradiances are reported at a mean solar distance of 1 AU and zero relative line-of-sight velocity with respect to the Sun. All of the data from this product are arranged into a single file in a tabular ASCII text format which can be easily read into a spreadsheet application. New data are appended to the file on a daily basis. The columns contain the date, Julian day, minimum wavelength, maximum wavelength, instrument mode, data version number, irradiance value, irradiance uncertainty, and data quality. The rows are arranged with data at each wavelength over the full TIM wavelength range, repeating for each day for the length of the mission.
