UAVSAR aboard the NASA502 has successfully completed the Gabon deployment and returned to Palmdale, CA on Sunday, March 13.  In all, we conducted 8 science flights in Gabon for terrestrial ecology study in coordination with Goddard’s LVIS lidar instrument and the European Space Agency’s two airborne radars from Germany and France respectively to support future NASA space missions (NISAR and GEDI).  We also managed to acquire some opportunistic data for wetland delineation over Ogooue River for the NISAR mission science team. 

On our transit home through New Orleans, LA, we were requested by NASA HQ to participate in the Gulf Coast flooding emergency response efforts organized by FEMA.  We acquired data around New Orleans as planned (land subsidence study, PI: Cathleen Jones) as well as three flight lines over the likely flooding areas near Monroe and Shreveport, LA and Longview, TX on Sunday afternoon, March 13.  The data were brought back to JPL for immediate processing.  By Monday morning (within 12 hours of landing) we already released polarimetric data of the three flight lines covering the likely flooding areas.  Bruce Chapman then classified the images using polarimetric decomposition technique to identify the inundated vegetation and open water.  These products have been sent to our colleagues at FEMA to assist NGA in their damage assessment efforts for the purpose of recovery assistance.  Here’s an example of the UAVSAR imagery together with the inundation classification map.

KTVU did a story about the February deployment of ASO. We had just finished collecting data in the Olympic Peninsula and then were flying the Tuolumne region out of Mammoth Lakes CA. That video is linked below:

To date NASA AVIRIS-NG imaging spectroscopy measurements have been acquired for 51 of 57 planned sites (>280 flight lines).   Water quality imaging spectrometer measurements of the Ganges (site 44) were acquired on the February 23. AVIRIS-NG with the aircraft is currently collecting data for a mangrove ecosystem site near Kolkatta.

AVIRIS-NG began flying science targets in India on the December 17, 2015.  Sites collected have science objectives spanning: coastal zone; mangrove forests; Asian soils; Asian forests; hydrocarbon alteration; mineralogy; agriculture; urban; and calibration/validation.  Science data acquisition flights are expected to continue through early March.

The ORCAS campaign has concluded, with 12 research flights in total (~98 flight hours).

UAVSAR/NASA502 had successfully completed four flights in Gabon on February 25, 27, 28 and March 1 respectively.  So far we have acquired excellent data over every site we have planned, including the German Space Agency (DLR) Cal/Val sites in Mondah and Rabi, Lope National Park, the Ogooue River Basin and mangroves for both hydrology and terrestrial ecology study, and the Pongara hydrology study site near Libreville.   Here is a NASA press release of our deployment to measure forests to Gabon:

Quick look image of the mangroves in Pongara National Park flown on February 28 (sortie 2) where we acquired 5 flight lines at slightly different altitudes for TomoSAR study.  This uncalibrated image was generated by UAVSAR team in Libreville on a laptop computer and it covers ~20 km cross track and ~120 km along track.  The polarimetric composite is made up of HH (red), HV (green), and VV (blue) polarization channels.  As expected, there are lots of forest inundation in the mangroves, which show up as reddish pink color in the polarimetric composite image.

The ASO team successfully completed the survey in Olympic Peninsula, WA, flew a few lines over transit targets in OR, and a full acquisition in Tuolumne Basin, CA. This wrapped up the first pre-season campaign.

02/19/2016

To date there have been nine research flights totaling 68 flight hours (30 remaining flight hours). Two research flights occurred last week on February 8 and 12 for a Western and Eastern Survey. 

02/16/2016

To date there have been seven research flights totaling 52 flight hours (46 remaining flight hours). Two research flights occurred last week on January 30 and February 5 covering the Patagonian Shelf and a Western Survey. Data is being processed at JPL, with the initial results looking promising.

AVIRIS Classic had another flight over the Aliso Canyon to measure the methane leak on the ER2.

AVIRIS NG continues the successful campaign in India.  Data has been collected in the Ahemdabad region.  The JPL team continues to work with ISRO on data transfer to JPL.
