From the Drought.gov website:
This workshop provides a unique opportunity for those involved in soil moisture research, monitoring, and applications to come together in an interactive format to exchange ideas and develop collaborations across their areas of interest and with the user community. This will be the 15th consecutive year for the workshop, which was started by the researchers who created the Marena, Oklahoma, In Situ Sensor Testbed (MOISST). It has now grown to be a premier event for sharing soil moisture research and applications.
