  1. Bridging Gap between Climate and Weather:The 20th Century Reanalysis Project (2007) INCITE Award for “20th Century Reanalysis” using an Ensemble Kalman filter to fill in missing climate data since 1892 PI: Gil Compo, University of Colorado, Boulder • Science Results: • Reproduced 1922 Knickerbocker storm • Data can be used to validate climate and weather models • Scaling Results: • 3.1M CPU Hours in allocation • Scales to 2.4K cores • Switched to higher resolution algorithm with Franklin access Sea level pressures with color showing uncertainty (a&b); precipitation (c); temperature (d). Dots indicate measurements locations (a).
