Total solar irradiance and terrestrial longwave outgoing measurements with CLARA onboard NorSat-1

Solar irradiance is the key energy input to Earth. In order to understand the Earth's climate system it is of great importance to continuously monitor the Total Solar Irradiance (TSI) from space. The Compact Lightweight Absolute RAdiometer (CLARA) experiment onboard the Norwegian micro satellite NorSat-1 is a SI-traceable radiometer and as such contributes to the record of TSI measurements. Moreover, CLARA also measures the terrestrial long-wave outgoing radiation (LOR) on the night-side of Earth. We present the latest status of the CLARA TSI and LOR datasets including the key data processing steps and compare the results with other available observations. Ultimately, we aim towards determining the Earth Energy Imbalance from space. We will discuss the achievements and limitations in direction of this goal.
