AirMSPI continues to support the FIREX-AQ/ER-2 field campaign. To date, about 40 hours have been flown resulting in many good fire acquisitions including the Williams Flats Fire near Spokane, WA. Coordination between the ER-2 and the NASA DC-8 aircraft has also been achieved as both aircraft worked this fire last week.

The 2019 OMG Airborne eXpendable Conductivity and Temperature Depth Probe (AXCTD) campaign is underway in Greenland. The AIRTec Inc. On 10 August the aircraft departed Goose Bay and arrived in Greenland. Science operations began on 12 August with a successful day of 10 AXCTD drops, and ITN/Channel 5 participated in the flight as part of the media event. Al Roker from The NBC Today show flew on the 13 August science flight. The Weather Channel and Associated Press will fly on 14 August. There have been 30 AXCTD probes dropped as of 13 August.
ASO completed the last snow surveys of the 2019 California snow year. The ASO team surveyed the Kings River basin on 27-29 July and the San Joaquin River basin on 1-2 August. The data will be processed with Level 4 snow products this month.
On 30 July, the ASO team completed an airborne survey of the Sagehen experimental forest in Northern California. This task is led by Dr. Jonathan Greenberg of University of Nevada Reno, under the NASA Carbon Monitoring System program.

ASO performed snow surveys of the Kings River Basin on 27-29 August. We expect to complete processing and delivery of the Level 4 snow depth and snow water equivalent products this week. This late season survey marks the last snow survey of the Kings River Basin in 2019 and will inform water managers how much water is carried over into the next water year.

Airborne Snow Observatory survey of the Kings River basin
ASO completed surveys of the Merced, Lakes, San Joaquin, Kaweah, and Tuolumne river basins 3-7 July. Level 4 snow data products from those surveys have been successfully completed and delivered for Merced, Lakes, and San Joaquin. In addition, ASO completed high resolution surveys of the Mother Lode mining sites in the western Sierra Nevada in support of a NASA HQ task.
The HyTES European campaign successfully ended on 30 June with a local flight near Duxford, UK.
Data was acquired over agricultural sites near Grosetto, Italy and in Southern England, as well as in urban areas over the cities of Siena, Italy and Milton Keynes, UK. A controlled fire was also observed in the Grosetto, Italy area.
The P-band radar aboard the AFRC C-20A (NASA802) successfully completed imaging of the complex terrain soil moisture in the Mammoth area on 26 June. In addition, we conducted a science demonstration flight imaging landslide area in Northern California as well as the densely vegetated Long Valley caldera (a large volcanic complex in eastern California) to study the use of P-band DInSAR (differential interferometric SAR) techniques over areas that typically decorrelates in L-band imagery over a short time period and deep-seated landslides.
The M6.4 and M7.1 Searles Valley earthquakes on 4 and 5 July respectively generated many requests for satellite and airborne DInSAR data to observe ground deformation along known and previously unknown faults during and after these major earthquakes. UAVSAR acquired data over China Lake back in 2008, an area to the southeastern end of the fault rupture. We have been asked to plan some future UAVSAR flights to image the China Lake area as well as the main fault rupture. UAVSAR data complement satellite SAR observations by imaging the affected area from different viewing geometry. The first UAVSAR flight is planned for late July.
ASO completed snow survey flights of the Kings, Tuolumne, and San Joaquin river basins in the period June 11-15. Data processing is underway. These surveys are performed in partnership with the California Department of Water Resources and the US Bureau of Reclamation.
HyTES received its approval to fly on 14 June and has completed three data collection days in Siena, Italy (the quicklooks from the first 2 days are posted to the HyTES website: http://HyTES.jpl.nasa.gov). The HyTES team coordinated its flights with several satellite overpasses (ECOSTRESS among others). They plan to continue flying in Italy for several more days before moving on to the UK or Germany.
ASO began its June campaign of airborne snow surveys in partnership with California Department of Water Resources, completing surveys of Merced River basin, Kaweah River Basin, and portions of the San Joaquin and Kings River Basins. Level 4 snow data products for Merced River Basin were processed and delivered within 48 hours.
ASO flies over the San Joaquin basin on 9 June, 2019.
