Efficient Multi-floor Indoor Mapping with A Versatile Rotating LiDAR System

We present sea level reconstructions from global 945 tide gauges since 1900. Our approach relies on a data assimilation technique that integrates various physical sea level observations and predictions. A prominent feature in our reconstruction is that it provides an ensemble of 35 complete time series at sites of tide gauge, which allows for direct statistical assessment. The average of our reconstructed global mean sea level shows strong agreements with other reconstructions.
