The team successfully completed two Mexico flights last week for the solid earth deformation study. During the month of July, 171 PolSAR and 37 RPI L-band science products were released. The team is in the process of putting a plan together and schedule for RPI browse and SLC product delivery. New calibration files were also generated for the last L-band (and P-band) engineering flights; the processor calibration algorithm was updated to increase calibration-phase accuracy.


The P-band radar has successfully completed two observations each over Metolius Pine, Oregon and BERMS, Saskatchewan. There is one more flight over each site left before heading back to Houston, TX. Weather conditions have been cooperating at both sites. Soil moisture at BERMS was wet (20-30 percent moisture) due to rain in the preceding week. The in-ground sensors observed a drying trend, which will be a good test for the sensitivity of the soil moisture retrieval algorithm.

The 3-day Gulf Coast deployment was successfully completed last week for coastal subsidence studies and oil spill recovery monitoring. At the IGARSS conference in Australia, the GLISTIN A PI, Delwyn Moller, presented a UAVSAR instrument status paper on our behalf to share initial results from the P-band radar (AirMOSS mission) and Ka-band radar (GLISTIN-A).
  • Science Team Meeting, October 23-25 in Austin, TX

Two engineering flights were conducted: one to check out the new Precision Platform Autopilot and the other to check out the L-band radar. We then flew our routine Sacramento Delta levee monitoring flight before heading out to the Gulf Coast on Tuesday for coastal subsidence studies and oil spill recovery monitoring. Initial assessment of engineering/calibration data showed that the radar is in good health.


The P-band radar successfully completed its Houston, TX deployment on July 23. We conducted 3 observations each over Walnut Gulch, AZ (desert shrubs) and MOISST, OK (temperate grasslands and SMAP cal/val site). Both radar and aircraft performed nominally. The JSC G-III and P-band radar are headed to Montana on Friday for the second summer campaign over Metolius Pine, Oregon and BERMS, Saskatchewan. The JPL radar team began delivery of L1 radar data from campaigns in February through June. Science team members continue to process higher level products. The PI is at IGARSS this week presenting soil moisture retrieval results from last Fall's campaigns.


The CARVE flight crew returned from Alaska and are taking well deserved vacations.

In the meantime, CARVE was recently featured on KNBC.

July 2-7, CARVE flew five missions over Alaska totaling approximately 25 science flight hours; locations included: Barrow, Dead Horse, Fort Yukon, and Minto Flats. Enhanced methane was observed at all of these locations.
On July 6, CARVE exceeded its Program Level Requirements and Investigations Success Criteria Threshold Science Requirement of 320 science flight hours (PLRA 4.1.2.d) during the flight to Barrow, Alaska! The 320 science flight hours were completed from May 2012 to July 2013.

On July 9, the L-band radar was removed from AV-1 without accomplishing the engineering flight because HS-3 is waiting to use the aircraft. Obviously this was a very disappointing development as the radar was successfully integrated to the aircraft and ready to fly two weeks ago. The Combined Systems Test on June 25 was terminated due to an aircraft engine fault. Dryden and Northrop Grumman teams spent a week troubleshooting the fault condition and determined the probable cause to be the Vehicle Test Computer on the ground and not the aircraft engine or computer. The team was hoping to get a flight off on July 11, but the window of opportunity on the aircraft had expired, and the team was instructed to pack the radar and return home. The next window of opportunity for UAVSAR flights is in October 2013, after the HS-3 mission.

The P-band radar completed its calibration flights at Rosamond on June 30 and is now on deployment in Harrisburg, PA. This deployment is the second set of observations of the year over Duke Forest, Harvard Forest, and Howland Forest. So far, the team has conducted two flights over Duke Forest and one flight over Harvard/Howland Forests; both radar and aircraft performed nominally. There has been a fair amount of rain in the east coast lately and the ground conditions were quite moist. Purdue's ALAR aircraft is also making airborne measurements of gas fluxes at Duke Forest this week. Science team members from JPL were at Duke Forest collecting ground sampling data while Harvard team members were at Harvard Forest on July 10.
The Radar team has begun delivering level-2 products from the spring 2013 campaigns to the science team. Higher level products are being generated as well.

AirMOSS has completed two (2) MOISST, Oklahoma flights and two (2) Chamela, Mexico flights. Last week, ground Built-In Test revealed an issue with the P-band RF electronics which was traced to a faulty Low Power Switch Network; the box had endured water damage, was replaced with a flight spare, and flights were resumed. The team is investigating the source of the water leak. In the meantime, the flight spare unit was sealed properly to prevent any water from entering the box. When AirMOSS returns to Ontario, the team plans to install humidity sensors to monitor the humidity of the nosecone to determine when water might have entered the pod.
