ICESat-2/ATLAS at One Year: Observed and Predicted Instrument Performance
Abstract
After one year on orbit, the Advanced Topographic Laser Altimeter System (ATLAS), the sole scientific instrument on NASA's ICESat-2 mission, is meeting its performance requirements. We present a summary of the instrument's observed on-orbit performance, with comparisons to performance during pre-launch testing and predictions of future performance. In particular, we focus on laser pulse energy, with predictions of laser lifetime; evolution of the instrument's time-of-flight bias; the solar background rate and other radiometric parameters; and the dead-time behavior of the photon-counting detectors.
