Total Solar Irradiance

Sample product image of NOAA CDR Total Solar Irradiance with a time reference of 1985 thru 2015. It depicts a primary scattered trace ranging between 1360 and 1362.

The dataset provides a high quality Climate Data Record (CDR) of Total Solar Irradiance (TSI).

The total, spectrally integrated energy input to the top of the Earth's atmosphere, at a standard distance of one Astronomical Unit from the Sun defines TSI (Wm-2). The data record utilizes solar irradiance models that determine the changes with respect to quiet Sun conditions when facular brightening and sunspot darkening features are present on the solar disk. Where the magnitude of the changes in irradiance are determined from linear regression of the proxy Mg II index and sunspot area indices against the approximately decade-long solar irradiance measurements of the SOlar Radiation and Climate Experiment (SORCE).
