Goddard Earth Sciences and Technology Center of Excellence

In 2000, the NASA Goddard Space Flight Center (GSFC) awarded a Cooperative Agreement to the University of Maryland, Baltimore County (UMBC), to create a Center of Excellence in the Earth Sciences. Based at GSFC, the Goddard Earth Sciences and Technology Center (GEST) is a collaborative program of research conducted under the auspices of a consortium of government, university, and private industry partners. Led by UMBC, this consortium is comprised Caelum Research Corporation, Hampton University, Howard University, and Northrop Grumman Corporation.

Caelum's ongoing projects include:

  • Research on a variety of topics related to airborne and spaceborne weather radar analysis generally and the TRMM Precipitation Radar specifically

  • Research on the environmental effects on sea-ice dynamics to further understand the physical processes in the Earth climate system

  • Creating and verifying a three-dimensional microwave radiative transfer model incorporating realistic hydrometeor composition and morphology

  • Classification and application review relative to remote sensing methods as the means of information support of contamination detection and monitoring in the Arctic

Caelum's research is an integral component of the successful efforts of the NASA/GEST team, resulting in a number of Caelum-authored/co-authored scientific papers (either published or presented at conferences). These include:
  • Estimation of rain attenuation from TRMM Precipitation Radar mirror image return

  • Integral Equations for a dual-wavelength weather radar

  • Bright-band modeling of airspace-borne microwave radars

  • Differential-frequency Doppler weather radar: theory and experiment

  • Principal-component Analysis of Sea Ice Motion from Satellite Data

  • Ocean Surface layer Drift Revealed by Satellite Data

  • Validation of Sea Ice Motion from QuikSCAT

  • Wavelet Analysis of Satellite Images in Ocean Applications
