Science Summary: The ongoing contribution of the Greenland Ice Sheet (GIS) to sea level rise is of continuing interest to the scientific community, policymakers, and the population at large. Geodetic determination of ice sheet mass loss is at the center of research on GIS contributions to sea level rise. There are many means for determining mass loss, but almost all rely on some form of satellite positioning, generally using the Global Navigation Satellite System (GNSS) or its subset Global Positioning System (GPS). The goals of the workshop are to 1) determine the community need for the current GNSS observation network in Greenland, 2) outline the science requirements for the network design, 3) define the path forward for the existing GNSS network, and 4) identify improvements to the existing network that will benefit the broader science community. Per broader impacts, the workshop will bring together investigators using data produced by the current network along with potential new investigators who can make use of GNSS network data. The workshop conveners plan to recruit participants from a spectrum from junior to senior scientists, and increase the diversity of the workshop participants wherever possible, by including funded invitations.
The objective of this workshop is to convene a 1.5 day workshop at NASA Goddard Space Flight Center in January 2017, with the purpose of defining a path forward for a Global Navigation Satellite System (GNSS) observation network in Greenland. The workshop will be held in conjunction with the 2017 NASA PARCA (Program for Arctic Regional Climate Assessment) Meeting. The goals of the workshop are to elucidate the current state of the GNSS network, illustrate the current uses of the network data (e.g., geodesy, crustal deformation, atmospheric modeling, space weather) and identify potentially new uses of the data, and determine the optimal configuration of the network moving forward (e.g., the ideal number of stations, the placement of stations, the replacement and upgrade of stations, and data management).
Logistics Summary: This project will support a 1 1/2 day workshop at NASA Goddard Space Flight Center in January 2017 (directly following PARCA 2017), with the purpose of defining a path forward for a Global Navigation Satellite System (GNSS) observation network in Greenland. There are many means for determining Greenland ice mass loss, but almost all rely on some form of satellite positioning, generally using GNSS or its subset Global Positioning System (GPS). Thus a network of geodetic-quality GNSS receivers is desirable.
Such a network already exists in the form of GNET, a joint US/Danish network of GPS receivers. Existing funding for GNET is drawing to a close, and the future of the network remains uncertain. Thus it is important to bring the various stakeholders and potential users of these data together to define the system requirements and the path forward.
The goals of the workshop are:
- Elucidate the current state of the network
- Illustrate the current uses of network data (eg. Geodessey, Crustal deformation, Campaign GNSS reference, atmospheric modeling, Space weather/ionosphere. )
- Identify potential new utility of the data
- Determine the optimal configuration moving forward: Ideal number of stations, Placement of stations, Replacement and upgrade of stations, Data management.
The workshop will bring together 30 to 40 people across a broad demographic mix including:
- Investigators using data produced by the current network,
- Potential new investigators who can make use of GNSS network data,
- Experts in the use of GNSS data for positioning,
- Experts in the use of GNSS as a remote-sensing tool (atmospheric water vapor, ionospheric electron content, and multipath utilization for sensing of conditions prox- imal to the station such as snow depth, vegetation, and mapping of transient areas covered by liquid water), and
- The people involved in actually deploying GNSS reference stations around Greenland.
Both NSF and NASA program officers will also be invited to attend. Together, this group will have the breadth and depth to accomplish the goals of the workshop.
No fieldwork is conducted.
