• The Development and Evaluation of the Global Gravity Model GGM05 

      Ries, John; Bettadpur, Srinivas; Eanes, Richard; Kang, Zhigui; Ko, Ung-dai; McCullough, Christopher; Nagel, Peter; Pie, Nadege; Poole, Steve; Richter, Thomas; Save, Himanshu; Tapley, Byron (2016-05)
      The GGM05 model suite consists of three mean Earth gravity field models: 1) GGM05S based only on GRACE data, 2) GGM05G based on the combination of GRACE and GOCE, and 3) GGM05C based on the combination of GGM05G and surface ...
    • Empirical Estimation of Present-Day Antarctic Glacial Isostatic Adjustment and Ice Mass Change 

      Gunter, B. C.; Didova, O.; Riva, R. E. M.; Ligtenberg, S. R. M.; Lenaerts, J. T. M.; King, M. A.; van den Broeke, M. R.; Urban, T. (2014-04)
      This study explores an approach that simultaneously estimates Antarctic mass balance and glacial isostatic adjustment (GIA) through the combination of satellite gravity and altimetry data sets. The results improve upon ...
    • Exploration of a Polarized Surface Bidirectional Reflectance Model Using the Ground-Based Multiangle Spectropolarimetric Imager 

      Diner, Diner J.; Xu, Feng; Martonchik, John V.; Rheingans, Brian E.; Geier, Sven; Jovanovic, Veljko M.; Davis, Ab; Chipman, Russell A.; McClain, Stephen C. (2012-12)
      Accurate characterization of surface reflection is essential for retrieval of aerosols using downward-looking remote sensors. In this paper, observations from the Ground-based Multiangle SpectroPolarimetric Imager (GroundMSPI) ...
    • First Results from the GPS Atmosphere Sounding Experiment TOR Aboard the Terrasar-X Satellite 

      Beyerle, G.; Grunwaldt, L.; Heise, S.; Kohler, W.; Konig, R.; Michalak, G.; Rothacher, M.; Schmidt, T.; Wickert, J.; Tapley, B. D.; Giesinger, B. (2011)
      GPS radio occultation events observed between 24 July and 17 November 2008 by the IGOR occultation receiver aboard the TerraSAR-X satellite are processed and analyzed. The comparison of 15 327 refractivity profiles with ...
