Over the weekend, as a blast formed the East Coast, a cautiously low blast absolute came from a arresting place: Reagan National Airport just alfresco Washington.
While a lot of readings in Washington neared 2 feet, the airport topped out at just 17.8 inches. So what happened? According to one report, acclimate professionals absent a lath lath they use to admeasurement snow. But it may aswell just be warmer at Reagan.
A National Oceanic and Atmospheric Administration backer says admiral will barrage a analysis of snow-measurement procedures to acquisition out what happened.
"Questions were aloft about the reading, and we wish to bigger accept what happened and why," NOAA backer Susan Buchanan said in an email Monday.
The federal bureau oversees the National Acclimate Service, which trains volunteers to account blast amounts in places area professionals don't do it. Major airport acclimate stations are professionally maintained, primarily through the acclimate account or the Federal Aerodynamics Administration.
Chris Strong, a acclimate account astrologer at the appointment adjoining to Washington Dulles International Airport, said the apparatus acclimated for snow accession abstracts is a 2-by-2-foot, white lath lath that sits on the ground. Every six hours, anyone measures the snow that's accumulated on the lath and again wipes it off. Those are again added calm to get a absolute measurement.
Strong says his appointment has an orange, aboveboard banderole that sits next to the board.
"You accept to mark it so you don't lose it in the snow," he said.
The Washington Post appear that the Reagan airport acclimate assemblage were FAA contractors who absent their lath snowboard in the blizzard.
Buchanan, the NOAA spokeswoman, wouldn't allocution about the address said snow observations are abstinent at airports "with the primary ambition of acknowledging safe aviation."
"National is the abutting airport to city DC, and that base provides us with added than 70 years of ceaseless altitude data," she wrote.
Other amounts in the District ranged from 21 inches appear by a acclimate account agent in the city's Adams Morgan neighborhood, to 26 at the Dalecarlia Reservoir, abreast the Maryland bound at the Potomac River. That account came from a acclimate eyewitness accomplished by the acclimate service.
The 22 inches at the White House, 3 afar from the airport, was appear by the Community Collaborative Rain, Hail and Snow Network, a nonprofit, advance accouterments sponsored partly by NOAA.
That accumulation was accomplished by retired acclimate account climatologist Robert Leffler, who has continued argued that Reagan National's altitude isn't adumbrative of the District as a whole.
"It's not that the data's bad. The data's acceptable for aircraft observation," he said. But "I consistently say, 'Not abounding humans live, plan or abound their aliment on an airport runway.'"
