The next generation Airborne Visible and Infrared Imaging Spectrometer (AVIRIS-ng) has been collecting data for the California Methane Survey. There have been flights over targets in the Southern California region and the San Joaquin Valley. A real time detection algorithm has been deployed on the flight computer for identifying the concentration of methane plumes. The flights will continue in CA through October 12, at which point the AVIRIS-ng and the King Air will deploy to New Orleans for flights on the gulf coast with UAVSAR and the ASO.

Aircraft Team: Friday, September 9 marked the first successful CORAL science data collection day for PRISM on board the Tempus Gulfstream IV!
The ER-2 and the P-3 performed three coordinated science flights on September 10, 12, and 14. Amongst many other instruments were JPL’s AirMSPI onboard the ER-2 and APR-3 on the P-3. Initial qualitative data analysis shows a distinct smoke layer embedded between the low marine stratocumulus cloud layer and mid-level convective cumulus clouds. A few high cirrus clouds were observed as well. One AirMSPI data acquisition was performed above the P-3 observing the solar radiance field above, within, and below the aerosol layer over one of the rare cloud-free Atlantic Ocean areas. Many of the main ORACLES observing goals could therefore be achieved early in the deployment.

AirMSPI quick look from September 10 showing the full range of viewing angles from 65 degrees forward to 65 degrees backward along the vertical image axis, which represents the flight direction (nadir is in the middle of the image). The DOLP image in the right shows polarization information in three spectral bands. A vertical cut through the center is shown on the far right to illustrate the spectral dependence of the polarization information, which is used in the retrieval of cloud microphysical properties.
The Ka-band single-pass interferometer aboard the AFRC C-20A jet is on its Western US glacier survey deployment (PI: Andrew Fountain). So far we have completed observations over glaciers in Sierra Nevada (California) and the Cascades in Oregon and Washington State.

All FOUR legs of the SMAPVEX-16 campaign were successfully completed. August 16 was the end of a second two-week campaign undertaken in Iowa. With this flight, the PALS
instrument has flown nearly 27 flights for SMAPVEX-16 – more than any previous SMAPVEX campaign. The campaigns were spread over a period of three months and two Cal/Val sites in Carman, Manitoba and Ames, IA.
Summary of the 2nd Iowan campaign: We flew a total of six site overpass flights over Ames, IA with a calibration maneuver over the Mississippi after every flight. There were no flight-scrubs. There was nearly a week’s gap between the first three flights and last three flights due to overpass schedules and optimal ground conditions.
AirGravity Science element: With reasonable weather last week, OMG’s AirGravity contractor (Sander or SGL) flew 4 science days last week.
SGL flew for a total of 24.5 flight hours. With Sunday’s flight, SGL completed OMG’s North East Science area.
Sidharth Misra and his team have successfully completed both Canadian campaigns for SMAPVEX-16. This was the second two-week campaign undertaken in Canada - the first one occurring in the middle of June. The instrument and aircraft both performed well throughout the campaign.
A total of six site overpass flights were flown over Carman, MB, which included a calibration flight over Lake Manitoba.
AirGravity Science element: With reasonable weather last week, OMG’s AirGravity contractor (Sander or SGL) flew 5 science days last week.
We have completed preliminary processing of all the data takes acquired in Greenland back in March for the Oceans Melting Greenland mission.
