The Total and Spectral Irradiance Sensor (TSIS) on the NPOESS is a combination of two solar irradiance instruments to monitor
the solar energy incident at the top of the Earth's atmosphere. The first versions of these instruments are currently
operating on NASA's SOlar Radiation and Climate Experiment (SORCE). The Total Irradiance Monitor (TIM) measures total solar
irradiance (TSI) with high accuracy and precision, continuing a data record that has been uninterrupted since 1978. This TSI
record is used both to determine solar forcing on the Earth's climate and to establish correlations with long duration
proxies of solar activity, allowing estimates of past solar influences on the Earth. The Spectral Irradiance Monitor (SIM)
measures the solar spectral irradiance from 0.2 to 2.7 microns. SIM data provide spectral resolution useful in determining
the response of different layers in the Earth's atmosphere to solar variations and in diagnosing the solar causes of
irradiance variations. A common pointing platform allows the two instruments to monitor the Sun almost continually without
interfering with other NPOESS spacecraft operations.
We present an overview of the TSIS requirements and sensors, status of the current SORCE measurements, progress on the
NASA/Glory TIM (which continues the TSI data record from SORCE to TSIS), and current progress on TSIS.
