ENRR

January – March 2016

The major El Niño of 2015-2016 presented an unprecedented scientific opportunity for NOAA to accelerate advances in understanding and predictions of an extreme climate event and its impacts through research conducted while the event was ongoing. NOAA's Physical Sciences Laboratory (PSL) played a central role in the NOAA El Niño Rapid Response (ENRR) field campaign to determine key mechanisms affecting El Niño's impacts on the U.S. and their implications for improving NOAA's observational systems, models and predictions. The ENRR campaign spanned the central and eastern tropical Pacific to California. Multiple types of observing resources collected measurements from the air, ocean, and ground between January and March of 2016. Of particular interest was the increased risk for intense wintertime storms and heavy rainfall affecting the US West Coast during this event's very strong El Niño. Read More

Kiritimati Island Observations

On Kiritimati (Christmas) Island, approximately 1,340 miles south of Honolulu, a radiosonde sounding system was set up with twice-a-day vertical soundings made continuously from late January through March 2016.

Scanning X-Band Radar in San Francisco

The radar will be deployed to the south San Francisco Bay as an experimental radar system, which will provide the more accurate rainfall estimates for the region that are needed to better manage and mitigate negative impacts. Starting in late January.

Daily Forecast Briefings

PSL researchers in Boulder, Colorado analyzed conditions and held daily forecast briefings, which were used to plan and coordinate field observations.
