Data Acquisition Computer Field Sites Used at sites where at least one of the instruments requires

a computer to acquire its data

• Types of instrumentation at these sites:

– radars, GPS-Met receivers, precipitation disdrometers, surface meteorology, precipitation gauges, soil moisture, snow depth

• Modes of communication at these sites:

– telephone/modem –  satellite internet

Example: Big Bend (BBD)

precipitation gauge

trailer to house computer(s)

precipitation disdrometer GPS-Met receiver precipitation

DWR Engagement

•  Field Assistance

•  Review Committee

•  Future Investment

Page 7: HMT-West End User Perspective End User Perspective ... HMT-West HMT-West Legacy HMT-East ... HMT-West_MLA.ppt Author: Chrystina Tasset Created Date:

Future Investment

•  Cooperative Venture Between DWR, NOAA ESRL and Scripps Institute of Oceanography

•  Snow Level Radar, Total Column Water Vapor, Soil Moisture Instrumentation

•  Ensemble Modeling, Forecast Tool Development

A Histogram of AR Strength

Conclusion: The Fall 2006 event in the Pac-NW was associated with a landfalling atmospheric river. This is similar to the Ralph et al. (2006, GRL) result for the Russian River floods from 1997-2006.

The event was tied for 2nd in terms of maximum IWV out of 118 events.

Conclusions

•  HMT-West has enabled opportunity for investment in equipment and decision support tools to aid emergency response in CA

•  Further development needed to fully transition research ideas and outcomes into existing or planned operational environment
