Analysis of gps data collected on the Greenland ice sheetFootnote¹

We thank Koni Steffen for logistical support at the Swiss Camp. This research was supported by NASA grants to the University of Colorado and Goddard Space Flight Center. The University NAVStar Consortium (UNAVCO) provided technical assistance. We thank the Jet Propulsion Laboratory, the National Geodetic Survey, Kort & Matrikelstyrelsen (KMS), and Bundesamt für Kartographie und Geodasie for supporting continuous GPS observations at Kulusuk (KULU), Thule (THU1), Kellyville (KELY), Scoresbysund (SCOB), and Reykjavik (REYK), respectively. Data for THU1, KELY, and REYK are freely available via anonymous ftp from the International GPS Service, or IGS (igscb.jpl.nasa.gov). Data from KULU and SCOB are available from UNAVCO (www.unavco.ucar.edu.) and KMS (forskning. kms.dk), respectively.
