doubly a day at National Weather Service Offices across the country , personnel department release weather balloons to measure atmospheric pressure , temperature , humidity and tip speed . In Nome , Alaska , Bob TenEyck or his partner would do that at 3 a.m. , a few hours after measuring the coke depth and snow . For 112 long time , these snow measurements in Nome were kept — until belatedly last year . Balloon - releasing was handed off to an automated Finnish system , and the office switched from a 24 - hour stave to a Monday through Friday , 40 - hour - a - week army of one : TenEyck .
TenEyck was n’t the only one left alone . By October of last twelvemonth , said University of Alaska Fairbanks climate specialist Rick Thoman , rural offices inKotzebue , Bethel , McGrath , Cold Bay , Kodiak , and Yakutat , were too undermanned to measure snowfall or snow depth . Many of these observatories boasted coke records dating back about a century . Well , they ’re skipping phonograph record now , thanks to progressively automatise weather observations . This has already compromised clime records in one of thefastest - warming places on Earthand could make it heavy for some Alaskan communities to get aid for severe weather condition events .
The job , said Thoman , is that snow measurement are astonishingly hard to automate . Rain is easy . Whether you use human hands and eyes or automatize tipping - bucket gauge makes no difference . As long as there ’s a seat for water to rest , it ’s easy to quantify .

Frigid snow , on the other deal , can be laborious to blarney into a bucket . It ’s also less dense . “ If I order you that we had three - hundredths of an column inch of liquid out of our one inch of snow , ” sound out Thoman , “ those are two very different number . ” discrepant character of precipitation , especially , can lead to mixed signal about how much snow you ’re bring .
automate sensors that use supersonic pulse rate to gauge Baron Snow of Leicester depth are accurate . But in the tundra , suppose Thoman where snow persists and winds rend about , snow can get mob up , spread out about , or compacted , it take several sensors string over a few hundred measure could give you a fairly clean sign about how much Baron Snow of Leicester there is .
“ The gold standard is still the trail human being , ” Thoman say Earther .
toy dog ca n’t replace human hands and eyes when it comes to measure snow for now . However , human hands are increasingly difficult to come by .
In the 1990s , the NWS set about aggressively flourish the Automated Surface Observatory System mainly to aid the Federal Aviation Administration ( FAA ) with gauging flight term . It ’s since been renamed the Surface Airways Observation internet ( SAON ) and feature more than 900 autonomous situation nationwide . Those station call for temperature , hastiness , and press information hourly . The SAON was also a bellwether — especially in Alaska — of not only increasingly automated weather collection networks but of NWS staffing issues .
Since 2009 , the NWS has been reduce staff at its 12 rural weather post along with three major Weather Forecast Offices . consort to alettersubmitted to Secretary of Commerce Wilbur Ross by several steamed Alaskan and Hawaiin members of Congress , 30 percent of these place were unfilled as of 2016 . The agency ’s Valdez office shuttered in 2016 . And under Trump , the NWS planned to close all 12 stay on Alaskan office . Yet , the three primal Weather Forecast Offices in Alaska have to cut across a territory that would be manned by 10 prognosis bureau in the Lower 48 .
The NWS has claim that staffing weather condition observatories , especially in rural Alaska , is increasingly hard . mediocre enough . Thoman also added that while military old hand coach in weather observance were long a reservoir for NWS stave , the DOD ’s coincidental electric switch to automated atmospheric condition observatories might have dry up some of that pool .
But Richard Hirn , the NWS Employees Organization ’s general counsel , has alsoaccusedthe delegacy of offering historically low payment for these positions in Alaska , then citing the ensue lack of interest as a driver of automation . Much likethawing permafrost releasing methaneand warming the atmosphere further , it ’s a feedback closed circuit .
Now , the SAON forms the backbone of Alaskan weather and climate observations . Only , it does n’t measure snowfall . After all , it was design to help the FAA . So , while every SAON system of rules has three pressure sensing element as a backstop , it has only one point of loser for both conditions and precipitation , Thoman say .
Hence why , in Alaska , according to Thoman “ there has been more missing temperature data in the last five years than there was in the previous 70 years combined . ” across the nation , onestudyalso intimate that human observers and automatise systems did not meet up around a third of the metre when it comes to precipitation . haste - character diagnosing only last out coherent because human observer were “ frequently overriding ” the automated composition .
The NWS augments its weather post with volunteer “ conjunct observers , ” often at fire departments and water treatment readiness . There are over 150 such perceiver helping hide data gaps throughout Alaska . However , while they can collect data on snow and deepness , none of their record run across foresighted - term , clime - platter examination .
The office also put to work with the National Park Service ( NPS ) to deploy a plethora of largely automatise weather condition observatories throughout ballpark . Yet only one such program — the National Resources Conservation Service ’s SNOTEL — collects rigorous snowfall and snowpack observation .
SNOTEL sites also only have one acoustic snow - depth detector , which limits their reliability in tundra environment . NPS physical scientists Pamela Sousanes told Earther that “ for the National Park Service weather stations , we ’ve now sustain about one station for every million demesne of land . ” That ’s an betterment , but with both SNOTEL observatories and concerted commentator being concentrated in the south and eastern United States share of the country closer to populated areas , there remain huge disruption in critical climate information in northwest Alaska .
Thoman say from Mae West of Anchorage and Union of Fairbanks , there are only a handful of place where accurate snowfall and deepness data are gathered . Past those blood , there are only a few 12 SNOTEL sites .
“ [ The NWS ] will tell you ‘ we ’re await for conjunctive observers in these stead , ’ ” Thoman said . “ But they should have started this before they turn off the snow mensuration . ”
And a push to fill vacant positions at NWS spot probably is n’t happening under an governance that wants to shrink it , and a Senate that has focused as much oneliminatingvacant positions as much as it has on fill them . According to Thoman , climatologists need foresightful - condition datasets sites like Nome ’s . Having a place that get observation a few solar day a month might be of some value to the weather service , but it ’s of no value to the climatologist . ”
In a slight flake or irony , a weather mesh build with an eye towards aviation , may be go away us flee unsighted , with compromised expulsion , into the hereafter of one of the fastest thaw environments in the earthly concern . And the next prison term Nome has arecord snowfall 24-hour interval — as it did this preceding wintertime — it might be laborious for it to request government assistance to keep the Ithiel Town pass . After all , how can you prove you ’re dealing with a book - breaking snowfall , when you have no record to kick downstairs ?
