Incident sunlight—the sunlight that falls directly on a surface—is the primary energy source that drives Earth’s climate. TCTE will measure total solar irradiance (TSI), or the total light coming from the Sun at all wavelengths, in order to monitor changes in the incident sunlight at the top of Earth’s atmosphere. The mission mitigates a potential and likely upcoming gap in an otherwise continuous 34-year climate data record following the loss of the NASA Glory mission in 2011. language code: en);

TCTE
The TCTE includes a Total Irradiance Monitor to measure total solar irradiance (TSI). This new instrument is similar to that providing data from NASA’s SORCE mission since 2003, and will be continuing those measurements beyond the SORCE mission. The TCTE was launched on 19 Nov. 2013 as part of the Air Force’s STPSat-3 mission and is intended for a 1.5 year mission. Solar measurements commenced after spacecraft and instrument commissioning, and TCTE TSI data from Dec. 2013 to the present are available via this site. http://lasp.colorado.edu/home/tcte/
