TL;DR: The National Science Foundation's Daniel K. Inouye solar telescope (DKIST) as discussed by the authors provides the highest-resolution observations of the Sun ever achieved with a 4-m aperture.
Proceedings ArticleDOI
Total solar irradiance measurements with PREMOS/PICARD
TL;DR: PREMOS on the French satellite PICARD is the first spaceborne absolute radiometer measuring Total Solar Irradiance that has been irradiance-calibrated in vacuum with SI-traceability as mentioned in this paper.
Journal ArticleDOI
Fourth World Radiometric Reference to SI radiometric scale comparison and implications for on-orbit measurements of the total solar irradiance
TL;DR: In this paper, the authors reported the fourth World Radiometric Reference (WRR)-to-SI comparison and compared three transfer pyrheliometer instruments in power mode with the SI radiometric scale.
Journal ArticleDOI
Total solar irradiance data record accuracy and consistency improvements
TL;DR: In this paper, the authors describe a method for correcting offsets due to calibration differences between instruments, providing a solar data record with precision approaching that needed for Earth climate studies, and explain the causes of instrument offsets and improve consistency between the international references upon which various instrument calibrations are based.

TL;DR: In this paper, the spectral and total solar irradiance of the French solar mission PICARD was measured using a combination of filter radiometers and absolute radiometers, and the filter radiometer channels in visible and near IR were characterized at PMOD/WRC and the UV channels were calibrated at PTB Berlin.
