On Wednesday, 22 August, OMG departed Goose Bay, and successfully launched 13 AXCTD probes in South East Greenland and landed at Kulusuk, Greenland.

The next two days 23-24 August, OMG deployed 60 AXCTD 60 in South East Greenland. On 25 August, OMG flew north to Scoresby Sound fjords and launched an additional 16 AXCTDs. For the four science flight days, OMG deployed 89 AXCTDS probes!

The L-band radar aboard the Armstrong C-20 aircraft is currently on the two-week ABoVE (Arctic-Boreal Vulnerability Experiment) deployment in Fairbanks, AK.  We have successfully completed 6 of the 9 science flights, and both the radar and the aircraft are performing well.

The Next Generation AVIRIS (AVIRIS-NG) had a successful week of flights in Alaska for the NASA ABoVE campaign.  The 2019 ABoVE campaign is now complete.

The Classic AVIRIS (AVIRIS-C) flew a successful flight over the San Francisco Bay HyspIRI CA Box on Thursday with the NASA ER2.

This past week we successfully conducted an L-band engineering flight followed by two science flights in California.   We have scheduled 8-10 local flights to catch up with the science observations that have been postponed since late spring.  These flights include the Sacramento Delta levee monitoring, the San Andreas Fault monitoring, and the Slumgullion, Colorado landslide study

ASO is currently surveying portions of the Klamath National Forest, Shasta-Trinity National Forest, Plumas National Forest, and Lake Tahoe Basin in partnership with the US Forest Service.

AVIRIS-NG is flying out of Zurich over target sites for both University of Zurich and the European Space Agency. The instrument has been operating nominally and the campaign has been moving along without any issues. We expect the flights for this year to end around mid-July.

OMG‘s Airborne eXpendable Conductivity, Temperature, and Depth (AXCTD):  Last week, the AXCTD team installed three adjustable attenuators into the distribution amplifier module.  With the attenuators installed, cables with the proper length could be ordered.  Early next week, the team expects all the required cables to be delivered and final bench testing can be started.

OMG’S GLISTIN-A Radar mission:  Last week, OMG’s GLISTIN-A team started processing OMG’s 2018 GLISTIN-A data.  Three lines were processed, including Jakboshavn glacier.

The Ka-band Glacier and Ice Surface Topography Interferometer (GLISTIN-A) is currently on deployment in Honolulu, HI to study the Kilauea volcano eruption.  The objective of this deployment is to use GLISTIN to detect changes in Kilauea’s topography associated with the new lava flows, with the goal of measuring the erupted volume as a function of time and ultimately the total volume of the event.  If successful, Principal Investigator Paul Lundgren and his colleagues at USGS plan to use the GLISTIN data to quantitatively evaluate their models for evolution of volcanic processes.  Here’s a NASA press release that highlight’s the research effort:

So far we have imaged the southeastern portion of the Big Island covering Kilauea summit and the east rift zone down to the coast on three different days: May 18, 19, and 21.  The data from May 18 & 19 were hand-delivered by Paul Lundgren to JPL on Sunday night where members of the processing team were waiting to start processing the data to determine if the radar has sufficient sensitivity to measure the topography changes associated with new lava flows. Within 24 hours we were able to generate some preliminary amplitude and height products that showed changes due to lava activities from May 18 to May 19.

The current plan is for GLISTIN to remain in Honolulu to make two more observations within the next week as volcano eruption continues to be active.
