4. Objectives: 1. Make accurate measurements with high precision of total solar irradiance, connect them to previous TSI measurements, and continue this long-term climate record. Provide TSI with an accuracy of 0.01% (100 parts per million) based on SI units and with a long-term repeatability of 0.001%/yr.
5. Objectives: 2. Make daily measurements of the solar ultraviolet irradiance from 120 to 300 nm, with a spectral resolution of 1 nm. Achieve this spectral irradiance measurement with an accuracy of better than 5%, and with a long-term repeatability of 0.5%/yr. Use the solar/stellar comparison technique to relate the solar irradiance to the ensemble average flux from a number of bright, early-type stars (same stars used by the UARS SOLSTICE program)
6. Objectives: 3. Make the first measurements of the visible and near IR solar irradiance with sufficient precision for future climate studies. Obtain daily measurements of solar spectral irradiance between 0.3 and 2 µm with a spectral resolution of at least 1/30, an accuracy of 0.03%, and a long-term repeatability of better than 0.01%/yr.
7. Objectives: 4. Improve the understanding of how and why solar irradiance varies, estimate past and future solar behavior, and investigate climate responses.
