The application of radio-echo sounding (RES) to thickness measurements of glacial and sheet ice has been demonstrated since the early 1960s. The concept for this approach can be traced to 1933 at Admiral Byrd’s base, Little America, Antarctica where the first indication that snow and ice are transparent to high frequency radio signal was observed.
NASA's Modern Era Retrospective-analysis for Research and Applications: Integrating Earth Observations
There are advantages and disadvantages to reanalyses for climate study. The main advantages are that global Earth observations (disparate distributions in space and time) are assimilated leading to uniformly gridded and globally available data. Reanalyses also combine many different types of observations into a single analysis.
