2010 Annual Report
ARS will direct the research testbed, leading the investigation and analysis of the results for incorporation into the SMAP Science Team Data Archive. Provide equipment and installation of in situ soil moisture sensors and assist in the collection of physical samples for calibration and validation of the sensor testbed.
OSU will be providing local logistical support for the testbed including site maintenance and communications support for the instrumentation. Also administer a gravimetric and vegetation sampling regimen on a regular basis for calibration and validation of the sensor estimates with the support personnel funded by this agreement.
Data from four base stations can be downloaded via cellular technology, but OSU is maintaining and downloading data from several other satellite stations which have larger data production rates and cannot be easily transferred via cellular networks. Many of the sensors require a settling time before the data can be considered accurate, but many of the stations are starting to give realistic time series information.
Future research will involve calibrating the in situ sensors to the gravimetric collections being conducting and analyzing the time series of the different instruments for the collected time period. Additional efforts will include a vegetation removal experiment, where portions of the field will be burned as part of another experiment and will influence how some of the sensors respond to moisture.
The ADODR has monitored the progress of this project through email correspondences, conference calls and periodic meetings with Oklahoma State University scientists.
