Attached please find the 2017 AAC daily report for AirMOSS flight #3 – a transit from Yellowknife NT to Fairbanks AK. Key acquisitions occurred over the Slave River Delta (Fort Resolution), Scotty Creek, Fort Liard, Kluane Lake, and Delta Junction.
Fuel and time pressures forced the descope of 2 lines over Kluane Lake, but these will be acquired with L-band radar and the optical sensors later in the campaign.
May 1—Mooney (ATM-C)
-
On Monday 1 May the AMT-C team executed a marathon 1400 nautical mile excursion from Nome across the North Slope to Fairbanks. Conditions across the North Slope were still frigid, but areas south of the Brooks Range showed significant signs of thaw. Attached please find the summary of that flight.
Thanks to Colm and Justin for the photos and to Kathryn and Sonja for data analysis.
Apr 30—Mooney (ATM-C)
-
The ATM–C team flew a 2–leg sortie from Fairbanks – Bethel – Nome on Sunday 30 April. Interior Alaska showed regions of mixed snow and exposed land, with corresponding enhancements in the near surface CO2 and CH4 signals. Western Alaska still seemed in the grip of late winter, although there are the first hints of spring in the CO2 and CH4 data.
Thanks to Colm and Justin for the photos and a good flight.
Apr 29 —Mooney (ATM-C)
-
Saturday 29 April saw the Atmospheric Carbon flights continue from Inuvik to Fairbanks. The flight was originally planned to go to Deadhorse, but conditions were superior for follow-on flights in Central Alaska, so the decision was made to go to Fairbanks instead. This allowed for a Sunday 30 April flight to Nome and the Seward Peninsula.
Conditions from Inuvik to Old Crow to Fort Yukon dominated by frozen lakes and snow cover; however, the vertical profiles in all locations show clear indications of elevated near surface CO2 and CH4 concentrations. This suggests that the spring thaw is under way.
Thanks to Colm Sweeney, Steve Conley, Justin Pifer and the ATM–C team for photos, data quick-looks, etc.
Apr 28 & 29Mooney (ATM-C)
-
The 2017 ABoVE Airborne Campaign continues with flights by the Atmospheric Carbon measurements team
- Thursday 4/28 from Yellowknife to Daring Lake and back
- Friday 4/29 from Yellowknife to Inuvik
There are clear signs of regional scale spring thaw in the vertical profile data – enhanced levels of CO2 and CH4 above background, although the enhancements near the surface are small suggesting that much of the signal is coming from outside the ABoVE domain.
