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).
